Cleaning a Da-Lite

post #1 of 52
Thread Starter 
I have a Da-Lite tab tensioned Cosmopolitan Electrol with a Pearlescent surface. The rear surface has developed a stickiness to it. I have cleaned the back with Simple Green about every six months. Later it will start to hesitate going down and I know it is time to clean again. Early this week, it got about half way down and stuck to the drum and went back up and jammed. I thought it was time for the trash. We took it down and took it apart. We unrolled it and the only damage was a crease across the middle. We put it back together and re hung it. After hanging for a few hours the crease disappeared. I need to find out what to clean this thing with. I sure don't want something like this to happen ten years from now. We are senior citizens.

I had Da-lite Tensioned Cosmopolitan Electrol too with HCCV screen material. I had similar problem to you. After only 1+ year, the screen developed a stickness both on the front and back of the screen. The bad thing was that, the coating of sticky stuff on the projection surface severely affected projection quality. I contacted my local Da-lite dealer/distributor and they were no help other than saying that I could trying cleaning with mild detergent. I tried cleaning both the front and back surfaces with mild detergent, but could never completely remove residue on the screen surface which of course was visible during projection.

The screen also developed severe waves despite being a tensioned screen and that was just over a year old. Again I contaacted my local dealer/distributor and they were of no help at all. They asked me to take a photo and they would send the photo to Da-lite and asked for help. But in the end, there was no help

It seemed that the only solution they offered was to change the screen material, but the cost was about 80% of ordering a new screen. So of course I declined. Now I have changed to a Stewart Firewawk screen and couldn't be happier with both the screen quality and service of the Stewart dealer. I am not saying you should change to a Stewart, but I am just truly disappointed with quality and services of Da-lite screens. I hope you will have better luck than me!

Thanks for the replies. Roland: It sure sounds like we have had a similar situation. My first screen shrunk in the middle. When they ship to a place like Arizona, they should put more tension on the cables. When they sent me a new one, the first thing I did was take a link out of the tension cables. I bought my first one in 1999 and the screen that they replaced it with was built in April of 2001. I bought mine from Cinemasource. They are the ones who went to bat for me.

It would be nice if Blankenship would chime in here. That is if he still works at Da-Lite.

I also have a DaLite Tab Tensioned HCCV with the same condition. I contacted DaLite and asked them what to do - they said that if my screen was manufactured after 2001 then I should clean it with Simple Green. I told them that I purchased it in January 2001 - they said it "should be" ok. I said what would happen if I had one previous to 2001 - they said that without the additional coating they began applying in 2001 it could damage the reflective area of the screen.

I also have now what appear some sort of surface damage from the sticking that are visible during viewing. I have yet to clean the screen and try to leave it down most of the time, but it goes right back to sticking when it is rolled up again.

Needless to say I am somewhat pissed. This thing was a bitch to install - I would hate to have to do it again. I have not been very pleased by the response from DaLite. If I could get maybe a 50% exchange credit I would (maybe) be less perturbed, but just having to scrap it and start over is not acceptable. I will not buy another DaLite product in the future.

If you remove the cover at the end of the screen, the one to get at the wiring, on the back side of the cover should be a label with exact build date.

That was exactly my problem. I cleaned the front and back surfaces and once I rolled up the screen, the sticky stuff just got deposited on both the front and back surfaces again. I also tried to leave it down most of the time after I cleaned it, but the screen still needed to be rolled up occasionally and the whole process just happened again and again. plus the fact that it was either not really totally possible to remove all the deposit or residue form the projection surface, which was visible during projection and my screen also developed severe waves. If paying 80% for the price of a new screen just to change the screen material would guarantee that the whole thing wouldn't happen again, I might have considered. but of course there was no guarantee and neither Da-lite or my local dealer/distributor could offer an explanation as to why it ahppend and how to prevent it, I had no option but to change to another brand. I am now very happy after changing to a Stewart Firehawk. needless to say, I would never buy another Da-lite screen again or recommend anyone to buy one.

Ken:

If you decide to try and clean the screen, don't use Simple Green straight. Da-Lite said to do that about a year ago and have since changed. I used it straight on the back of mine and it just made every thing worse. Now we have been trying to get that stuff off with plain water.

I'll eventually try to do the cleaning, but I wish Da-Lite would give very explicit instructions on what/how to do it. Plus, I don't even like the idea that I have to perform cleaning at all! If I have an adult NS household and basically put the screen down to watch something, then put it right back up again, then the issue that a residue forms at all is disturbing. For me, this is as bad as a Firestone Tire on Ford Explorer - if they have a defect in their product they should be bending over backwards to make it right!

Anybody mention class-action lawsuit?

Ken:

Go to the Da-Lite web site and there is a tab that says e-mail. Tell them that you want to clean the screen and they will send instructions. If it still says to use Simple Green straight, don't do it.

I think Angie of Da-Lite told me the date was April of 2002. Don't clean the front until you find out for sure.

I totally agree. the point is why should there be a deposit on the screen in the first place? Does Da-lite even have any idea what the problem is? If so, would just come clean and admit the problem and give us a solution. We shoud not have to clean the screen every time we roll it up and down again. there should be a permanent cure for the problem. Does Da-lite care at all????

I sent exchanged a flurry of emails with them a few months back - this is what I got (including this attachment Cleaning Tensioned Screens):

Ken,

Jack is out for the week, so I am handling his email. To answer your question, that surface should be cleanable. Anything made in 2002 or after is cleanable, so you should have no problem. To give you a little insight, even if it was a non-cleanable surface, then cleaning it would not destroy the screen. What it would do is wipe off the additional reflective coating that Cinema Vision has. So you would end up with a Da-Mat (1.0 gain) surface instead of the 1.3 gain that you are used to. The reason that we do not recommend cleaning a screen that that would happen to, is because it is very difficult to get ALL of the reflective coating off. It would give you an unevenly reflective screen.

But either way, you are ok. Something manufactured in 2002 will not be a problem.

Let me know if you need anything else.

Jack,

I purchased my screen on 1/18/02, so I assume I have one of the ones that
cannot be cleaned. So, then what can I do to fix my problem with the screen
"sticking" when it is being unrolled? This is not something I want to live
with permanently. Worse yet, the sticking continues to get worse until
something else breaks.

I'm sorry, Ken, but Cinema Vision manufactured before 2002 may not be
cleaned by any means. Cinema Vision screens manufactured in 2002 and
thereafter may be cleaned by the method described. Please let me know if
you have more questions.

Hi Jack,

Your instructions state "DO NOT ATTEMPT TO CLEAN CINEMA VISION....." -
my screen is a cinema vision. So, what should I use to clean it?

Thanks.

Ken

Thank you for your inquiry, Ken. I have attached the cleaning procedure
below. To prevent a recurrence, allow your screen to hang extended for a
day or two every few weeks. I hope this informatiuon is helpful. Thanks
again!

Sticking Da-Lite Cinema Vision 131" screen.

My screen is about 4 years old, but about 6 months ago I started having
some problems with sticking when the screen is unrolled. Is there
something I can do to keep it from sticking?

My bad from before - I thought it was 2001, it was 2002.

I would like to know where this sticky stuff comes from. It must have been put there during the manufacturing process. It seems that Da-Lite makes a very good case and mechanism. They just don't know how to make a screen. I would think that a screen should never need to be cleaned.
post #15 of 52
An update...

I called Da-Lite on Thursday and talked to one of their specialists. After discussing my discontent with the sticking and the permanent marks (which are visible upon viewing) which have been caused by the sticking they have agreed to replace the screen.

They will be sending me a replacement screen on roller. I will have to pull down the screen and exchange the roller, then send the old one back to them.

Bob, they said that the sticking is caused by the vinyl materials used. Apparantly, the vinyls leetch-out something or another which causes the stickiness. They appear to have reformulated the chemical make-up to eliminate the problem - I hope they're right.

I'm not looking forward to pulling down my screen - it was a bear of an install. But, all things considered I will be very happy to get back to normal.

Holy Cow!! Can you imagine how many screens are involved? I thought it was something like that. My roller is even sticky. Changing out the roller will be a bear of a job. They should have just sent a whole new screen.

Ken: Who did you talk to at Da-Lite?

Bob - you have a PM.

post #19 of 52
I am encountering the same sticky issue on the front and back of the screen. I cleaned it with mild soap and water and it seemed to clean it ok but not completely. I originally thought I was having problems with the projector because it was effecting the image quality until seeing the residue on the screen and the back being a feel of oily, sticky Vinyl.
I have a tab tension Cosmopoliton electrol with 1.3 Cinemavision image surface.
Has anyone had any luck with any other cleaner. I read of someone trying Pledge on a different brand screen.
Any thoughts would be great.
post #20 of 52
Guys, I have the same problem. I tried to clean with dish detergent and water but it didn't help. We have two screens mounted next to each other and one is having this problem. I'm afraid the other will start having the same problem. Should I call Da-Lite to get these replaced?
post #21 of 52
We have this sticky issue with two Da-Lite screens purchased in December 2007. It's unbelievable that they were still selling screens with this defect in 2002 and possibly later. I finally got frustrated enough to either get our screens clean or destroy them in the process. I recently used Sanford Expo White Board Cleaner which seems to have done the trick... It contains "2-butoxy ethanol/acetate, isopropyl alcohol" and so maybe it will eventually turn the screen into a puddle of goo, but so far so good.

Hi Folks

I am thoroughly impressed by the various tips etc I found while searching for a method to clean my Da-Lite High Contrast Da Mat screen.

I tried warm water and it made even more streaks.

I then tried denatured alcohol - and although this method certainly seems to remove streaks, again I found new streaks appearing.

I used low-lint rags (the closest thing to dustless that I could find) to wipe the denatured alchohol onto the screen and then seconds later I used a clean rag to wipe it off.

If I put copious amounts of alchol on the rag and clean a section with one long stroke it seems to work well. I then very quickly wipe the alcohol off, again in one long stroke. But moments later small streaks will appear on either side of the cleaned section (and if I am not careful also in the middle where if I did not wipe it clean fast enough).

Can anyone please advise... can anyone see something I am doing wrong?

Thanks,
David

As noted on another thread, very hot water alone does a fabulous job. I just cleaned mine that way, using vertical strokes on 18" sections at a time, and drying with a soft terry towel, I cleaned the front screen surface twice and the back once. The sticky stuff is gone and the screen is now without any streaks and noticeably brighter -- like new.
post #24 of 52
I fell into the same trap as the rest of you. I have a Dalite, Damat. It felt sticky so I tried cleaning it with dilute soap and water. The screen became very streaky. I tried cleaning and scrubbing to no avail. The hot water trick also didn't work. Out of desperation I tried Windex. It worked beautifully. No more streaks. The surface is very matte after cleaning but I think that it makes the image look better. I suspect that the gain may be somewhat reduced but I couldn't tell.
post #25 of 52
I'm thinking of purchasing a 92" tensioned cosmopolitan electrol, does the sticky substance still ooze out of new screens, or was this only an issue with older screens and has since been fixed?
post #26 of 52
I am disgusted by the support answers that Da-Lite gave above (Ken, thanks for posting). Agreed, if there is a known issue, don't hide behind language like Don't clean your screen under any circumstances or you will reduce your gain... I can't even use my screens if they're doubled back on themselves, wrapped around the spool the wrong way, and the weight has passed over the faceplate's ridge. One screen was so bad that it pulled the Da-Lite nameplate right off. Take that!

I have a feeling that the vinyl will leach out for the life of the product, so they're unwilling to give an answer until you say "replace my screens." Let's hope the chemical isn't toxic since we're all getting so intimate with it. Has anyone tried adding talcum powder? I know it will make a horrible mess on the black side panels, but if it doesn't get too gummy, it may work to lube the screen. I used Simple Green today, and it just smeared. Other times, I have just wiped my palms across the screen and the tackiness was temporarily reduced.

PS: On a positive note, if you play football, wipe your hands on the screen and it works like Stick-em! Yay! Super Bowl here I come! Watch me on your Da-Lite screen! (unless it's all jacked up, of course)

I will check my newest screen and see when it was built. I think it was 2003 or later, and it's the stickiest yet.
post #28 of 52
I've had my Da-Lite Cosmo Electrol Tab Tensioned HCCV screen since about 2003. It stays rolled up all the time unless I'm watching a movie. I've never had any problems until the past 6 months or so. I started noticing more texture to the screen and then started noticing some horizontal marks in certain places. When I went up to touch the screen, I noted the sticky feeling that has been mentioned here.

I tried using a wet cloth (albeit not very hot water) and had no success. I then read this thread and tried the Windex. Windex took the greasy/sticky film off, but it left tons of streaks (just like it always does when I try to use it on windows). So I tried what I use on my car windows--Stoner's Invisible Glass and a microfiber cloth. That worked perfectly! Took a little work to make sure I got the whole surface cleaned well and evenly, but it looks 100% better. I don't think it changed the reflectivity, but of course I can't say for sure. It actually seems brighter, but maybe that's just because I got the sticky film off, that couldn't have been helping.

Hope this helps someone.

Stoner's worked for me. Thanks for the suggestion. I think it's because Stoner's gets sticky stuff like sap off. But you'll lose the gain.

Has anyone had any luck with Da-Lite? I called and they played pretty coy about the screen issue, but a call to the local dealer showed that it's a very common issue. Why bother paying the premium for Da-Lite when I could buy three cheapie Elite screens for the same price?
