Chlorinated vs Non chlorinated brake cleaner?

[bunnspecial]

Chlorinated for me every time-it works better, evaporates faster, and is non-flammable.

At work, I pulled the last 1L bottle of carbon tet off the shelf in the stockroom and locked it in my office. It's in the same(locked) cabinet as some of the valuables(NIST calibration weights and other NIST standards, platinum eletrodes, and stuff of that nature) along with the real nasties that we don't want in general circulation(potassium cyanide, etc). There are times when it's hard to find a substitute for the carbon tet, although it's rarely used.

Chlorinated works better - and while I am a little bit of a tree hugger, the CARB stuff is useless beyond oil and some light grime. It was perchloroethylene, dry cleaning solvent.

Just don't spray the stuff into a catch pan and drain into your used oil - otherwise that used oil becomes HAZMAT and the unlucky store/shop that needs to have it hauled off will pay(in CA) or pay extra to get rid of it.

Isn't one of them harmful to plastics ? I forget which one.

The CARB stuff with acetone and toluene is.

Hopefully you see P.71 from this link

You can zoom in and see what type of soil you want to get rid of and
the first through fifth best solvent.
Notice acetone doesn't show up. Trichloroethylene, toluene, and pentane do.

Supertech non chlorinated isn't very kind to turkey blasters. It gives it a nice frosty finish and must be allowed to dry for about 10 minutes or else it's covered in fingerprints.

Non chlorinated could be sold as wheel clearcoat remover. Beware.

Why would you use it on a wheel's finish....?

Anyway, we only use non-chlorinated in the shop and go thru a bunch of it. I try to use the parts washer as often as possible, but it'll leave the parts a little oily. A quick blast with brake cleaner and their clean and dry.
