Metal Polishing & Ultrasonic Cleaning.

Having done projects over the years restoring old motorcycles, cars, vans and trucks etc, something I get get pleasure from, turning an old tired piece into a nice shiny part that shows off its grandeur even after many years. 

Ultrasonic cleaning removes residue from parts that cannot be reached and causes no harm to the part. 

Carburettors are a primed example as modern fuel leaves residue you cannot get to especially if the engine isn't run regularly.
