FWIW, as a purple cleaner, oven cleaner, and gasoline user, I'd try them
in
that order, unless you don't mind the gasoline fumes, in which case that
would be second.

I mix my own oven cleaner for cleaning my charcoal grill but it's a
bugger
to get straight lye these days. The only over-the-counter retail source
I've
seen identified by others is Roebic Crystal Drain Cleaner, which I buy
from
Lowe's at $11.00 for two poundsouch!! It's now $1.98 for two pounds
online, under different names, but then I pay $10 shipping. d8-(

I do buy 20 pounds or so at a time online once in a while. You want 100%
sodium hydroxide crystals or pellets; mix 20% with water by weight; dump
in
some diatomaceous earth to make it stick a little to the grill. You can
use
potassium hydroxide but it's more expensive.

Mix 40% for cleaning drains, and stand back...At 40%, it's like thin
syrup.


What do you think of this "stuff" for cleaning the grunge out of a
two-stroke expansion chamber? Castor oil is great for bearing life, but
kinda messy in the exhaust... thanks for any suggestions.

BTW, don't use this stuff (or Easy-Off) on aluminum or galvanized steel. It
eats aluminum and zinc for lunch. It's no problem on other platings, but
chrome is porous, and it will get through it and attack the copper plating
underneath, bubbling off the chrome, if you leave it on too long.

That's the voice of sad experience. d8-(
