Cleaning
NOTE: You can do the following cleaning method of aluminum oxide paste to polish the flat
surfaces of the parts. For either cleaning method, the final step you must sonicate the
parts in an ultrasonic bath of methanol for at least five minutes. Dry off the parts using
lint-free tissue and/or clean compressed Nitrogen gas to prevent solvents from drying
on these parts and leaving a residue
1.
Mix together aluminum oxide and de-ionized water and a few drops of
methanol to make a watery paste.
2.
Dip a wooden-stick cotton swab or a foam-pad swab in the solution and clean
the darkened areas on the source. Work quickly to prevent the mixture from
drying on the surface.
3.
Place the cleaned components in de-ionized water prior to rinsing to prevent drying.
Rinsing
1. Add 50 mL of methanol to a 100 mL beaker, insert the source parts, and
sonicate them in an ultrasonic bath for at least ten minutes.
2. Carefully drain the methanol.
3. Add 50 mL of acetone to the 100 mL beaker, insert the source parts, and
sonicate in an ultrasonic bath for ten minutes.
