Now it was worse with bold streaks after drying - a little panic at that point. Second pass I did a thorough rinse of the wet cloth and got a small quart bowl of steaming hot water and put just a touch (about 5 drops) of Dawn dishwashing soap. Some sites recommended Dawn or Simple green. I dabbed the cloth into the water just to get it wetter on the surface I would use against the screen and I used a little more pressure and lightly scrubbed the screen top to bottom doing 1/3 of the screen left to right to stop and wipe the excess water off starting at the top and wiping to the bottom without lifting. This time it turned out perfect - no streaks and can't tell any difference in reflectivity across the screen. everything looks great. Can't believe it.
In between the first and second pass while waiting for it to dry hoping to see if the streaking would go away, I was actually looking up the price of a replacement screen.
BTW... that low-cost bulb now has 1608 hours on it. Still bright as the day I put it in.
Nice, Mine is going about 600 hours and no issues. I wish i had bought another bulb as a spare. The price is now about $48 on amazon i think.
