Bead blasting

For now, see the page on EngineCleaning

Some people have blasted with walnut shells or plastic granules with success. Another media to blast a case or heads is sodium bicarbonate. It's available at places that sell animal feed. It's not fast and it can only be used once as it powders upon use, but it produces nice results. Afterwards, a good soak in water and it will dissolve and fizz away without leaving contaminates behind.
