Discovered something by accident when cleaning old plastic. Not just cleaning off years of grime but the yellowing of plastic with age. It doesn’t make plastic “like new” but it’s a heck of a lot better than it was. Clorox… works wonders.
I cleaned some old plastic storage bins last night, used regular cleaners, 409 and similar. It cleaned off grime but that was it. They were multi-quart size for stacking on shelving.
I have a few small parts storage cabinets also, various sizes. The oldest has 60 drawers (30yrs old). The little drawers had yellowed with age. I have a couple that are relatively new also. First pic… (they were also in dire need of reorganization, needs have changed with the decades).
Anyway I tossed a couple multi-quart bins in my shower intending to soak the little drawers this morning. I grabbed a jug of clorox, splashed some into the large bins then filled them with water.
After an hour soak I was amazed how clear the little drawers were. The yellowing was gone… 2nd pic. 4 little drawers that had been soaked, next 4 not, next 4 soaked…
The large bins I used for soaking are also clearer, still using those so don’t have a pic. All my old bins and drawers are going to get a good soak before I'm done. (also makes it easy to get the old white labels off)
