WHITE CHEMICAL WR-90 is a liquid, non-conductive, organic compound formulated as a solvent degreaser. It is specifically intended for degreasing, cleaning, and preventive maintenance on all types of electrical motors, generators, switch gear, control panels and rheostats. In addition to its use as an electrical device cleaner, WR-90 is an excellent degreaser for use on all types of machine tools, lathes, etc. It is also an effective degreaser, tar and wax remover for use on industrial and drilling equipment. WR-90’s controlling drying time allows it to remain on equipment surfaces sufficiently long to remove oil, grease, wax, carbon, grime, tar, acrylics, adhesives, etc., yet it dries fast enough to eliminate the need for wiping. WR-90 may be used on electrical motors and devices while they are in operation. It creates no fire hazard since it will not flash or support combustion at its initial boiling point.

WHITE CHEMICAL WR-90 can be applied by immersion, wiping, brushing, hand spraying or power spraying as received. For use on non-electrical equipment, WR-90 can be used as received or may be diluted with up to 15 parts of short range mineral spirits, diesel or varsol, depending on the amount and type of accumulated dirt, grease, etc. WR-90 will cause softening of some plastics; therefore, it is suggested that the product be tested on a sample before using.
