Cleaning Vinyl Covers?

[Kan Yozakura]

I'm new.  Hello to everyone; forgive my newbieness.  Anyway, my question...

I just got a Turbo Duo bundle,  and everything is mint/fine...except that a couple of the vinyl Hucard covers are yellowed to a nasty piss color.  Is there any way to safely bleach/clean them?

I have some like that too, but I never even thought about cleaning them before. I'm sure they would be easy to clean just by soaking them in clean water or bleach, but don't take my advice .

I was thinking about that...I've read some other threads on this board about soaking a PCE shell in bleach with great results, but I don't know how it would react with the vinyl.  If I had an extra, torn up one, I would test that, but I'm short. ;_;

I think he's talking about the hucard sleeves.....I only have one that is kinda dirty, but havent thought about cleaning it.
