Acetone

Solvent for easy cleaning. Recommended.

Overview

Acetone is a useful solvent for the plastics industry. Furthermore it has many general purpose uses, and is quite safe to humans in small amounts - it is not dangerous unless exposed to fire or ingested. It can be purchased at the grocery store as Nail Polish remover. Small amounts of Acetone evaporate when exposed to air.

Safety

Acetone is the basic ketone

Acetone is flammable. Store Acetone in a closed container. Dirty Acetone can be saved and re-used until you deem it is too dirty. It is not corrosive in small amounts, and does little more than dry human skin (though keep away from open wounds). For full details of the health and safety of Acetone refer to a MSDS/SDS.

Use in a well ventilated area. More or less, the only way you will get in trouble is either being near a source of flame, or working in a small room without ventilation (and using a lot of acetone).

If you do manage to get acetone on fire, it will burn like an alcohol. But it will not explode. Acetone vapours however are flammable, and can cause an airborne flame. If you somehow manage to boil the acetone, this can be a danger (a spark can cause acetone gas to ignite in a fireball). Understand the potential of what you are working with.

How to Use Acetone

Cleaning Tools

Acetone can be used to clean off many kinds of uncured and cured plastics and polymers from tools. Tools can be soaked in an acetone bath over time. It can be used along with e.g. a metal drywall scraper to remove slightly cured resin from surfaces.

Preparing Surfaces

In cleaning a concrete floor, Acetone can be used as an alternative to water as it will evaporate quicker. This is done when preparing a concrete floor for finishing (epoxy, urethane, etc). It also helps to clean any detergents or oils left on e.g. epoxy floors after they are have been cured.

Cleaning Hands

Acetone can be used to clean resins off of hands or surfaces. Apply to a rag, and wipe your hands in the rag, until the resin is dissolved in the solvent.

Tips / Techniques

Retail Store Acetone

Acetone can be purchased from grocery stores in household amounts. It can also be purchased from Advance Coatings in small to large quantities. Note that these acetones are not 100% equal. The quality from consumer/retail stores tends to have a more recycled smell/scent, than what we sell. As someone who has used Advance Coatings acetone for many years, I instantly recognize that consumer acetone has a 'dirtier' or 'rougher' scent to it. It's not as pure. Not including nail polish remover, which is only some percentage of acetone, along with fragrance. But even consumer supposedly 100% pure acetone can vary in quality.

For general purposes it may not matter, but it is something to be aware of.

Reusing Acetone

We reuse acetone as much as possible. Even when Acetone gets dirty, it is still a viable solvent. It's wise to store different levels of 'dirty' acetone. I.e. keep a container of pure acetone for finish cleaning. And keep a container or two of dirtier acetone for rough cleaning.

Evaporation

Keep acetone containers closed when not in use. It will evaporate into the air (and is flammable). This can also be of benefit, i.e. if you pour some acetone onto a surface for cleaning, it will evaporate relatively quickly.
