Cleaning Methods
Three cleaning methods (in different situations)
General Cleaning
Ruling Mark
Use just tap water for general cleaning.
(The water should merge the article but not
exceed the ruling mark.)
For professional use (jewelers, opticians, dental labs,
dentists, artists, etc.) use special cleaning liquid.
For smears, add a few drops of detergent into water
to enhance cleaning.
For large articles, partly cleaning as shown.
