That combo works Mike. I bought the exact same thing from Sally's Beauty Supply. I used a plastic container from Walmart to drop everything in, as I did my entire Amiga case, keyboard, and mouse, and came out great. I dumped a whole bunch of Oxy Clean in mine. Didn't cause any foaming but had to be stirred a bit to dissolve.
I did have a couple of caveats. The Salon 40 only came in 32 ounce bottles. Next time, I may just go with the 20, as two gallons is roughly 17 dollars, and you need every bit of that to submerge everything. The 40 gets a little expensive when buying in 32 ounce increments, and I'm not sure how much additional benefit your getting for the extra money, if any.
Second, I had a problem keeping some of the pieces completely submerged, so have to figure that out without leaving a mark by placing something heavy on it. Maybe tying some fishing weights to the underside with fishing line.
Third, the 40 developer will burn your hands, and eyes, so make sure that you wear some protection. I played tough guy and it turned my skin white and burned any cuticle or cuts that it came into contact with.
Use the UV from sunlight. I tried a black light for night time processing, and it was a waste of time. I guess if you have a true UV-B bulb, it would be different, but you'll be spending at least $50, so I just used the free sunshine.
I was getting nice results in a 4-5 hour time frame, so I was able to cook two different plastic batches per day.
Definitely works and you can see a discernible difference when completed.
