 We used trichloroethane for cleaning for years, small drums to fill Milwaukee Sprayers:

 Which brings a good question:

 Trichloroethane is excellent for cleaning and as a bonus it won't burn. Not readily at least.  Our vendor said it was discontinued due to regulation years ago.

Yup, damage to the ozone.

 Since government intervention, we now use brake cleaner. Typically:

 or

They still sell the chlorinated version, see my link above.

 which is more expensive and a virtual flamethrower in a sprayer; shoots fire a meter and a half at 100  psi (which can be seen as entertainment). In regular daily use, brake cleaner is a fire hazard and attention need be paid to that.
