Powder blasting of the cylinder

I got hold of a “new” cylinder for my bike. Seems to be in a good shape but is full of old burned oil. Not easy to clean. Can the powder blasting do the job ? Lets try ! The powder is ordinary baking soda and will not do any harm to the cylinder.

Drying up after a wash with water and soap. A layer of WD40 inside the cylinders.


I’m very pleased with the job. Nice and clean, like a new one from the factory.
