But the blade needs to be CLEAN. A pitch-encrusted blade takes more
than twice the power a clean blade takes - particularly in petrified
saw-dust. A good shot with something like "brake kleen" will disolve
the crud very quickly and you won't believe the difference in the cut.

Safer, and usually also handy, is SimpleGreen. Soak the blade in it
for 15-30 minutes, rinse (the pine tar falls off), and reinstall. Save
the soak for a dozen or more blades. It lasts when bottled. I use a
regular old pie tin for holding the solution.

nothing unsafe about brakleen, but it won't cut pitch like carb cleaner
will.

Brakleen works great on carbs, too, both for starting and cleaning the
exterior, if you're unlucky enough to still be stuck with one.

I don't particularly like breathing all those VOCs, and you have to
use a bit of caution with any flame near its use, and you don't want
to spray/drip onto any painted surfaces with it. I only use it
outside on windy days.g

SimpleGreen is much easier.

So, -yeah-, Brakleen has safety concerns...if you're awake enough.

a: brakleen is not flammable
b: brakleen will not hurt paint. we use it all the time to remove tar
c: brakleen will not clean the junk off a carb that needs to come off.

Hmm, the stuff I have now is not Brakleen, it's O'Reilly Brake Parts
Cleaner and it contains methanol, acetone, and toluene.
EXTREMELY FLAMMABLE.

Brakleen containes Tetrachloroethylene, chloroethylene, and petroleum
distillates.
Hmm, NONflammable.

Brakleen non-chlorinated contains methanol, acetone, heptane, and
toluene.
EXTREMELY FLAMMABLE.
