Sherwin Cleaner DR-62:

DR-62 Cleaner-Remover is used in the penetrant process to remove excess, nonwater-washable penetrants from part surfaces, e.g., Sherwin DP-40 Dye Penetrant (visible red) and Sherwin RC-65 and RC-77 Fluorescent Penetrants. It is a manual “wipe on” and “wipe off” material and, consequently, recommended for small areas. DR-62 may also be used for generally cleaning oily, dirty surfaces. DR-60 is especially suitable for cleaning prior to the application of inspection penetrants. DR-62 is widely found in machine shops, foundries, and overhaul shops; it is a good, all purpose cleaner.

Sherwin Cleaner DP-51:

DP-51 is a red colored dye penetrant liquid used to locate cracks, laps, pores, lack of bonding, and similar surface flaws in any insoluble, nonporous substance including both ferrous and nonferrous metals, ceramics, glass and many plastics. Referred to as the “visible dye penetrant” method or “color contrast “method inspection

Sherwin Cleaner D-106:

D-106 is a Developer consists of refined white particles suspended in acetone to give enhanced sensitivity for locating tight, incipient flaws; by solvent and capillary action, it pulls flaw-entrapped penetrant to part surfaces for display against a white background.
