Since this weekend my was booked solid (graduation party, and mothers day stuff) I took Monday off, and WAS going to Retr0brite my apple //c, then looked at the weather and saw it was going to be "overcast and 40% chance of rain"

Great, so ... since I was running around like a madman today anyway I went ahead and did it, if you look at the last picture in the post above I am still trying to discribe its yellow, ... maybe mayonnaise mixed with plain yellow mustard?? Also I wanted to see how well the "drugstore" 3% mix would work on a machine so badly yellowed.

few weeks ago I hit up "dollar tree" (a store that every thing is only 1$, hit and miss goldmine) and got 6 1 litre bottles of 3% hydrogen peroxide and a half pound tub of "LA's totally AWESOME Oxy booster", I love that store

last night after my friends graduation dinner I soaked the case in warm water with regular dish soap, then scrubbed it with a nylon dish brush, that alone made the case nearly a shade lighter + it removes the question of "is that 25 year old coffee spit, or 25 year old flu snot?" from the keyboard

today I got up a little earlier and cleaned a couple clear plastic bins out, and made my mix which ended up being 3 bottles of3% hp, with 1, 4 gallon office waste can (clean) of water + 1 scoop of oxy per each bin, it took 2 of my bins to lay everything out

and the results! after 8 hours still a hint of yellow on the worst places, but dramatically better, and due to constant stiring, flipping and poking, everything is very even in between the different case pieces, the parts are uniform with no splotches etc and no damage to the print on the case

Over all I am very happy with the 3% mix, and while it did not get every single bit of yellow off of this really bad case the first time, it was well worth the little (but lets face it, hand scrubbing keys is tedious) effort, and the questions from my dad when I went to check my grill :))
