The amount of WHITE CHEMICAL WR-80 required
will depend on the amount and type of fouling to be removed. However,
one part WR-80 diluted with 10 parts water will handle most ordinary
applications. For very heavy buildups of oil, grease and hard
to remove contaminants, spray the entire surface with undiluted
WR-80 and allow to penetrate for approximately 30 minutes before
rinsing with water.
WR-80 can be applied by wiping, brushing, mopping,
spraying or with power washing equipment. WR-80 rinses away with
water without leaving stains or streaks.
