That's what I'm going to do
One guy said he wanted to submerge his whole plastic part in the stuff. He used about
a gallon and a half of 3%h.peroxide and what ever else he mixed in. I'm going to just
spray,spread if needed and either wrap plastic wrap or use a seal able plastic bag,
depending on what I use it on first. My gray Kenmore canister would be a good thing
to try first. They say you can even do white sneakers! Don't have any but maybe a
white or beige bumper on an upright. It doesn't have to be white either, just some-
thing that has darkened, could be blue or red. What color was your part you worked
on?
