People often ask what the best cleaning solvents are for removing different liquid or partially cured Smooth-On rubber, plastic, foam colorants and other materials from a variety of surfaces.
After testing a variety at Smooth-On, three solvents stood out as "best" for removing Smooth-On liquid or partially cured materials from surfaces;
Warning: these liquid solvents are flammable. Caution and appropriate storage/handling care is required. Read all manufacturer warnings before using.
We selected these particularly because 1) they evaporate quickly and 2) you can generally find them anywhere at DIY and other stores.
Other solvents are effective at cleaning; however an issue can be slow evaporation or even a residue left behind that can cause cure inhibition of some Smooth-On materials applied after a surface has been cleaned.
Solvents that may leave a residue and cause inhibition include turpentine and d-limonene (citrus cleaner).
Solvents may damage or dissolve some substrates (such as modeling clays, acetates, etc.) As always, a small-scale test "off-model" is recommended before applying solvent to a valuable model or surface.
Applying – apply a small amount of solvent to a high quality "shop towel" and wipe surface clean. Never allow the solvent to pool. Allow solvent to fully evaporate for 2 minutes before applying new Smooth-On material. Do not use low quality paper towels or cloth as fibers can be left behind on the surface.
These cleaners are available at many Smooth-On distributors.
Unless you are using a silicone or alginate expressly made for applying to the skin, you do not want these materials in contact with the skin.
Remove from the skin as soon as skin contact occurs while the material is still in it’s liquid state. Using a soft cloth, lightly wipe clean with Acetone or Mineral Spirits and then wash affected area with soap and water.
