Simple Green and Castrol Super Cleaner, and many carb cleaners are

caustics

that dissolve aluminum. There are many warnings about using Simple Green

around

aircraft. Don't do it. It is not good for bearings or any similar

materials.

We use the Castrol Super Cleaner to remove aluminum oxide stains from

the

white trailer sides. But, you must rinse it off right away, with lots of

water. It

turns aluminum white very quickly.

I have used the kerosene used for the home heaters for years. It is

minus the

Smell of Kerosene, and is a harmless solvent. It has a low vapor

pressure so

it does not flash off quickly. It can be flammable but not very. I have

a

Little Giant fountain pump in the bottom of a 50 pound grease can that

has been

running in kerosene for 20 years.

For small parts, I use lacquer thinner in a coffee can.

Remember to break a side seal in half and sharpen one end of it and wrap

the

other end with masking tape for a handle. Clean the carbon out of the

side

seal grooves.
There may be an amazing amount of carbon in there.

I once spoke to a motor boat racer that would put thin water hose down his

carbs (maybe his idea off water injection )he claimed that when he stripped
down the motor their was no carbon build up at all. I have noticed that with
my own personal experience with blown cylinder head gaskets, the cylinder
where the water leaked through allways has less carbon. Maybe we must just
induce some water into the intake while the motor is running before we strip
it down.
