acetone is a solution (literally), so the best result is when you use it first time. after a while, the acetone is not very clean and after you take your tire out, it will dry as a layer of glue on your tire.
for tire compound, don't put clay compound into acetone, it will shrink and get totally ruined. Other than that, others seems fine, but doubt as good.
for foams, I found close cell foam may shrink (get smaller) after the acetone. While open cell will get back to the size, it will get a lot softer after. I'd recommend to take out the foam before you put them into acetone.
