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.

Try Simple Green. (Now in lemon scent, which I prefer.) It cleans
burnt pine tars off tablesaw blades in 15 minutes. I'll bet it would
work in an expansion chamber. A gallon might fill it. Tape one end
and fill 'er up. You can prolly reuse it several times.

$6.99 at a Homey's Despot store near you. ($8.99 original)
