Keep electric pressure washers on a GFCI outlet, never point the wand at people or pets, wear eye protection with polishers and chemicals, and read the label before mixing any cleaning products. Read our Safety Disclaimer.
Garage Fit Check

- Cans: the listings state 11 oz, 10 oz and 10.25 oz cans, while the CRL listing states no can size.
- Power: these are aerosol sprays, so no outlet or cord is involved.
- Before the first job: check that the listing names rubber seals and weather stripping, and that the finish dries clear where it lands.
