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 don't use those hollow corner seals with the rubber plugs. They are made of
powdered iron, and break very easily, as many have discovered.

What do you use for the corner seals Lynn? Jim Mosure just broke one.
