Thanks!

EASY LIFT OFF (ELO) paint and decal remover looks to be something like 95% v/v Dipropylene Glycol Monobutyl Ether and 5% v/v Isobutanol. By the name, it sounds like something that should be used on rockets. By chemical composition it seems to be much safer than a lot of the other paint stripper formulations (I am a retired chemist).

It's made by Testors. Basically, a low grade paint stripper. I just brushed it on the pieces, let it soak for a few minutes, then scrubbed with an old toothbrush, and wiped off the lifted paint Repeat as necessary.

Methylene Chloride based strippers are far faster.
They also will destroy most plastics.

May any Chemists or Physicists chime in with my perfect solution, please? Pretend that I've a painted, vintage Estes R2-D2 Leg & Dome that I need to render clear and fresh for repainting.

In my Heart of Hearts I'd like to add said parts to a bucket of Strong Acid, or Methylene Clhoride, and watch said parts dissolve to nothingness. Most times though, I just wonder about Acetone as a solution. There must be a better alternative to paying $12 for a cup of ELO.

A Home-Store Analogue for ELO? Cheaper than $12 a cup?

Back when I was much younger I used undiluted Pine-Sol to strip paint from styrene plastic parts. I soaked the painted parts in a container overnight or longer and used a tooth brush to scrub off and remove the paint. I washed the plastic part in water and let it dry overnight before I repainted it. I attributed the ability to remove paint to the pine oil in the Pine-Sol. The Pine-Sol formulation has changed over the years and the "Original" commercial product no longer contains 8 - 10% pine oil as per this old MSDS: https://web.archive.org/web/2016030...andcleaner1.pdf

Check out this thread on the model railroader that was posted well before the formulation change: http://cs.trains.com/mrr/f/88/t/49017.aspx

You can still purchase the original 8.75% pine oil product visit: https://1221market.com/collections/pinesol

6 X 48oz (more than 2 gallons) for $31.99 should give you a life time supply!

I haven't tried the new Pine-Sol formulation that contains Alkyl alcohol ethoxylates and Glycolic acid to see if it would strip paint.

When I saw ELO in the post my mind immediately went to Electric Light Orchestra!

In my tiny, bity research into MEK, I read someone's blatherings about a splash of Mek dissolving an eyeball to the size of a Raisin. So that's what I'm gonna do now! (Splash MEK in my eyes.)

Aaaaaaah! Why didn't I wear Eye Protection?! This is the worst! OMG! OMG! MY eyes are raisins!

MEK or methyl ethyl ketone is a lot like acetone (also known as dimethyl ketone) both are very aggressive to styrene plastic and in high purity can be dehydrating to moist surfaces like eyes. Both are great solvents for paints and plastics like nail polish and ping pong balls. MEK is just a bit harder to evaporate than acetone.
