What type of detergents can I use with my SPX4004-MAX pressure washer?

Sun Joe® HOUSE +DECK WASH, Sun Joe® SNOW FOAM AUTO WASH, and Sun Joe® HEAVY DUTY CLEANER are specifically designed for pressure washers and are safe to use with your SPX4004-MAX pressure washer. Do not use household detergents, acids, alkaline solutions, bleaches, solvents, flammable material, or industrial grade solutions, as these could damage your pressure washer.
