Acetone is great for thinning fiberglass resin, cleaning fiberglass tools and dissolving superglue before hardening. A heavy-duty degreaser, it is useful in the preparation of metal prior to painting; it also thins polyester resins, vinyl and adhesives. It easily removes residues from glass and porcelain. Acetone is also used in biological research contexts and in industry being a very important solvent and a reagent in organic synthesis. Acetne is also an intermediate in the production of bisphenol A and metaacrylate. It is most commonly used as nail polish remover.
A word of warning: Acetone is flammable, so please be careful.
