Works well but doesn't remove baked on - Hornady 110 Volt 9L Sonic Cleaner Hot Tub

This ultrasonic removes oil, lube, and light carbon wonderfully but does not work well for removing backed on carbon in silencer baffles. The cleaner works much better when using the main bin rather than the small parts bin. The instruction manual does not give clear information on how to properly use the cleaner, but with a little trial and error it can all easily be figured out
