cleaner, isolate the orifice from the side walls and all other parts. Do this by placing the orifice individually in a plastic cup in the cleaning hopper. This will help prevent mechanical damage to the sealing surfaces of the orifice. Polish the orifice with a clean pencil eraser. Blow off dust and debris after polishing.

5.Due to its unique stainless mesh design, the inlet filter of the Sherwood SR3601 first stage can be cleaned in the ultrasonic cleaner. Visually inspect the filter before and after cleaning. Blow the filter dry with clean compressed air.

6.Check the strength of any cleaning solution by placing a spare chrome-plated part in the bath for a few minutes longer than the time you expect to leave the parts in. If visible damage to the chrome finish results, then the solution is too strong.
