Gerber Edge Cleaning?

[jfiscus]

I usually clean with the gerber cleaning wipes which are saturated with 99% ISO Alcohol.
However I was going to be doing some DEEP cleaning this weekend and wanted to grab some extra alcohol to use the same swab a couple times to clear up some dead pixels.

So, would it be better to stick with the 99% Isopropyl Alcohol or use Denatured Alcohol?
I have heard that the 99% Iso leaves a bit of a film when you use it and that denatured is actually recommended for cleaning processors/computer parts?

Ive always used 99% ISO

I've always understood that using anything but cleaning wipes made for thermal heads or 99% ISO may damage the head.
