Given the microscopically rough (matte) surface it is important to avoid cleansers that include wax or filling agents. The wax will act to fill the imperfections in the surface to give it a polished look. Whilst such waxes are great to use on polished surfaces where they fill imperfections and provide a protective coat - they will leave shiny areas on your matte black surface and in time replace its matte finish with a splotchy polished one.
If you are not sure about your cleaner, and it includes chemicals you cannot identify then simply avoid it.
Avoid wax based cleansers!
Note: Success with cleaners and procedures is dependent upon such factors as the hardness and temperature of the wafter, using exact measurements of ingredients, changes in cleaning formulas and the condition of the product being cleaned. Since there are variations within these factors, KUBEBATH cannot guarantee the effectiveness of the formulas.
