Cleaning Stainless Steel Parts
Y
To clean stainless-steel parts
1. Remove contamination from all the surfaces you are cleaning.
a. Use a slurry of number 600 aluminum oxide in glycerol and a cleaning brush or
cotton-tipped applicator. Contamination appears as dark or discolored areas, but
often is not visible. The heaviest contamination is usually found around the
apertures, such as the electron entrance hole on an ion volume.
b. Clean each part thoroughly, even if no contamination is visible.
c.
To clean the inside corners, use the wooden end of an applicator cut at an angle.
d. Use a Dremel
®
tool with the polishing swab at its lowest speed to increase cleaning
efficiency, as well as decrease the time required to clean the items. To prevent personal
injury, be sure to keep the Dremel tool away from possible hazards, such as standing
water or flammable solvents.
