R&R Wash-N-Etch pattern cleaner removes silicone oil or other release agents from wax patterns before the primary ceramic coat is applied. R&R
Wash-N-Etch is a biodegradable, completely safe product for cleaning wax patterns. R&R
Wash-N-Etch contains naturally occurring
d-limonene, derived from citrus fruits, as the active ingredient. 

R&R Wash-N-Etch also acts as an etching material for the wax pattern while it cleans off the release agent. This process allows for better slurry adhesion during application of primary coats. Better adhesion of the primary coats reduces opportunities for casting defects related to shell buckling or lifting.

R&R Wash-N-Etch is shipped in its most concentrated form. It can be diluted for use in the foundry.
