White PC Engine should be white

[esteban]

Bleach has always worked perfect for me. I use straight bleach with no added water. Let it sit for at least 12 hours. I generally let it sit over night in a small bucket in my bathroom. Then I wipe any marks left over off with a MR Clean Magic Eraser.

Keith will get back to you as soon as he can--it turns out he bleached his computer keyboard and the keys literally disintegrated a few minutes ago as he tapped a response to your question.

By the way... Keith says, "Hi!" and "TTYS "

I bleached another white PCE in 2012 and it looks brand new now. I didn't even soak it for very long or expose it to sunlight. I did scrub it with a tooth brush though.

MEDIUM SOFT BRISTLES, naturally.

I've never had it damage any plastic or make it brittle as far as I can tell. Then again I've never tried breaking a case on purpose to see if it's just as strong after bleeching or not.

Interesting. I let my yellow PCE sit in bleach for over 24 hours and it barely did anything. It's a little whiter but not by much. The heavily yellowed parts were hardly phased at all. I then let it set in 3% hydrogen peroxide overnight outside and nothing. Albeit it was cloudy all day but nothing seems to have much of an effect on this thing. I was expecting an nice white PCE but no dice.

Maybe some are genuinely stained while others just experience that side effect of the plastic composition?

Instead of bleach, why not just try straight chlorine mixed with water?

Nah, this isn't a stain. It's yellow on the entire back and right side as well as around the controller port. It looks like you'd expect from ABS yellowing. I guess I could try to get a higher concentration of hydrogen peroxide but I hate having to mess with all these potent chemicals. Makes me nervous.

PRO-TIP FOR SOILED CONSOLES: Instead of using weak-ass chlorine or bleach, you should use hydrocholoric acid to take the yellow (and residue) off of your soiled consoles.

elemental chlorine + water = hydryochloric acid


Stop listening to esteban. 

[Bernie]

I understand that, but you can control the concentration of chlorine by buying pure chlorine.

[TheOldMan]

Where would you buy pure chlorine?

[Necromancer]

You'd just end up with diluted hydrochloric acid, which still sounds like a bad idea to me.

[Bernie]

You can get 99 percent chlorine in most hardware stores.  Same stuff they put in wells when first dug too.  The granules I buy for my pool are 99 percent pure as well.  I've had chunks of it that didn't dissolve literally bleach the blue lining solid bright white in spots, happens when the kids mess with the dispenser.

[Necromancer]

Those granules (dichlor or a hypochlorate) are not pure chlorine.  That's why they're granules - pure chlorine is a gas at room temperature.
