I figure, if the disk is unplayable anyway, and I'm not slipping it into my PS4 or my Oppo,
so what, it's my gear, I'll do what I want to with it ..
In my case, it has been successful .. I was a recording engineer and producer for many years .. of course, nothing really beats a dedicated polishing machine ::
Lastly, if you have a Family Video in your area, many have an on site polishing / cleaning machine which might be worth a try ..
If you want to use WD 40 fine on optical media fine ,You do that on magnetic tape too ? .
Game stop Store or an independent electronic game store will have polishers also ,they can also send out optical media professional restoration if it's restorable .
IMO it's absurd to clean optical media with petroleum distillate and light oil compounds like WD40 penetrating oil is something I absolutely don't want on optical media , an optical drive transport or optical reader where if the transport needs lube a dry silicone spray is what to use in last few decades
To lube a disc transport dry silicone spray will dry quickly, it won't attract dust, which can clog or gum up moving parts. ...and there are safer methods than WD 40 to clean optical media
Perhaps your recording engineer career pre dates optical media like my electronics education neither of which change the facts here .
I have an inexpensive polishishing machine which is more plausible for an unplayable CD then I clean it with nothing more than clean filtered or distilled water and maybe a few drops of dishwashing liquid in a cup of water scale dilution to dampen a clean microfiber cloth with or try that before using the polisher .
In a pinch dry unscented cleanex will work fine wiping from the center out for optical media with fingerprint smudges .
Something like mild dishwash doad on a damp microfiber cloth at the extreme any polishing is abrasive by nature and optical players spin fast where the implications of abrasive residue or WD40 residue should obvious
All my optical media is on spinning metal with back ups or in the cloud anyway I prefer not to use optical media in 2017 .
