Clean with acetone varnish

Acetone is a solvent that is offered in small quantities to consumers and thus home improvement. However, acetone must be handled carefully because it reacts violently to many other substances. So too acetone on paint.

Acetone, a versatile solvent

Acetone has been known since the 17th century. Since the 1930s it has been used to make acrylic glass and acrylic plastics (polymethyl methacrylate, PMMA for short or acrylic). In addition, a is a raw material for the production of diacetone alcohol. With acetone the most different substances can be solved:

  • Resins (resins)
  • Oils and fats
  • certain plastics such as polystyrene or polyurethane (PU)
  • Cellulose acetate (acetic acid ester)
  • Rosin (resin from pine and spruce)

Resin-based paints

Many paints are based on resins, just like the synthetic resin paints. As a rule, these are all 2-component paints, ie paints that are mixed with hardener or thinner. For the cleaning of paint parts acetone is therefore absolutely unsuitable. In addition, it also dissolves various plastics such as polystyrene (colloquially better known under the brand name Styrofoam) and polyurethane.

Plastics and acetone

Polyurethane (PU), for example, is the starting point for construction foam. Therefore, you can remove PU very well with acetone. In addition to cartridges and disposable spray cans, special spray guns are also used for construction foam. These clean with acetone. But also spray guns for paints such as 2-component car paints can be cleaned after use with acetone.

Degrease before painting with acetone

In addition, you can also use the acetone to completely degrease parts to be painted or to remove oil residue. However, it should be bare metal parts. If there are still paint residues or primers on the workpiece, less aggressive silicone cleaner is recommended.

Clean the paint gun with acetone

A paint spray gun can be placed completely in a bath of acetone after painting. In addition, the acetone can certainly be used to remove paints. So almost as a paint remover. For example, old lacquers on wood or otherwise difficult to access areas for sanding can be perfectly dissolved with acetone. So you can also remove stains well with acetone.

Use of acetone in the household

In the house you can also use acetone to remove mold. However, you must also pay attention here to painted components, plastic seals and adhesives, as these can also be solved. Otherwise, acetone-treated parts are long mold-free.

Tips & Tricks

When dealing with acetone, keep in mind that it is not completely harmless. Acetone on the skin embrittles them and dries them out. In addition, the solvent can pass through the skin into bloodstream and bone marrow. If you inhale acetone, it can lead to nappies and unconsciousness. So if you want to dissolve lacquers with acetone or, for example, pre-degrease blanks for soldering, you should always ensure that the ventilation is very good.
