That's what I was going for anyway. XD

IPA does not dissolve plastic. The bets explanation I can come up for is that there was a crack halfway through the plastic.

I would very much like to say a proper sharp close-up. (Macro picture taken on a good camera.)

Yes. That's what I'm thinking.

I would never purchase less than that, else it will not evaporate as quickly as the higher percentages. 60% IPA means 40% water, water oxidizes metals.

The second post here seems to have the answer:

"What you seem to be doing is leaching the plasticiser out of the plastic piece and what you see as film are residual solids. I would recommend a less aggressive cleaner.

Ever notice the foggy film you see on the inside of your car windows? That is plasticizer evaporating from the dash and other plastic pieces. When I lived in the desert this was so bad that the dash would harden and ultimately crack. The only way to slow this down was liberal applications of Armoral type products and towels to keep the sun away."

It definitely looks like film. And I looked up the percentage of the alcohol I used...

91%!!

I usually use 60% - 75% alcohol so mine was very strong. There might be something in clear boys that make them crack more easily. The plastic definitely feels harder. I'm not sure if that's because it's glossy or not, but it does...

It is true that rubbing alcohol can cause crazing in plastics, but so can ordinary tap water, if you leave it soaking long enough. EDIT: looked closer at picture. This is a fracture. No solvent would do that.

The diagonal crack was mostly already there, so it was fractured before hand, but it branched off in other directions. Only the inside of the layer of plastic is like that though... It's kind of like a bubble...

I'm just going to say
pressure + Alcohol = Crack

I mostly suspect your back light created extra pressure at that point and when you closed it up, the crack may have appeared slowly.

It may have been the case, but it appeared minutes after cleaning it. That may have just been enough to crack it. I'm going to experiment with this odd occurrence to see whether it was pressure, or sensitive plastic. Thank you for your input!

It has a rather low acidity level, evaporates in seconds and dissolves very few materials. Of these materials we have most residues and something called polyvinyl butyral. polyvinyl butyral is a material used as a bonding agent for glass. If in fact that it was used in the plastics of clear game boys, it would probably not be high enough quantity to elisist anything more than a cloudy after effect on the surface of your bay, then again there is no proof that it was used at all.
Ipa may damage nothing else. That is a crack son, not a result of dissolving or burning.
