Option 1, Straight Super Clean.
Super Clean, I buy at from Wal-Mart for around $8.00 a gallon its in the automotive section.
It eats paint, superglue, and softens green stuff. I has been safe to use on Plastic, Metal, and Resin models. It does not de-bond plastic cement.
Use it warm (around 100-100 degrees) for faster results. Or you can let it set in a covered container and soak. You will still need a toothbrush to scrub off the small bits and recessed areas.
Important:
- It eats paint, like on cars and walls, it probably would damage some types of counter tops.
- It eats thin medical gloves.
- It breaks down the oils in you skin and will dry you out, so wear heavy duty chemical gloves.
- It can be reused I have a couple of rigid reusable coffee filters that I strain out the bits out paint with every once in a while.
Option 2, Ultrasonic cleaner with Super Clean
If you can get one of these on the cheap you should. Speaking of eBay, I picked this sucker up on the cheap ($65vs $400 + retail) on the good ole eBay. This is a Spaulding & Rogers ultrasonic cleaner made for the tattoo industry. It heats up and removes paint from models, I have been using Super Clean in this unit and it works great. I have found other medical grade equipment like this at a reasonable price online/eBay.
This thing does most of the work for you and really cleans the paint out of the small detail areas very well.
For those that have asked or will ask, the specs on this unit are.
