so spent a couple hours cleaning a piston out of my freebie 5.3 last night
heavily carbon build up to the point the rings were sticking
got the idea to try some super clean in a small pot and heat it on BBQ
tried it tonite
took about ten min a piston and it just washed off
pistons look almost new
going to pull the rings off and see how it does cleaning out the ring lands
yes it's pretty ******* but it worked

Pretty much any chemical works better warm, the problem is that many of them (vapors) can become downright dangerous, toxic or explosive

Be careful. Read the warnings. I would not use a BBQ (open flame), but rather something like........

Go to the thrift stores and find a small electric hot plate / warming pad / or even something like an eletric stew pot / croc pot

good point on the dangers of doing this
yes I wouldn't use anything flammable in it
I made shure what I used was not going to go boom lol
and use with good ventilation I did it outside

was thinking a thrift store crock pot would work great
for small parts
and I have used oven cleaner before but this worked way better

I would be careful with the caustic things like oven cleaner and aluminum
I quoted both these guys because when messing with chemicals both these things are worth remembering.

Go to your local GM dealer and ask for a few cans of rust penetrant/inhibitor and heat valve lubricant. I've been using it for my whole career, and I've never seen anything that works better on oily grime, carbon and varnish. Does a fantastic job right at room temp, and will not etch metal parts. Use it in a well ventilated area because it STINKS.
