Can I use bleach in my pressure washer?
You must NOT use any household bleach with your machine. By using them you will damage the seals and o-rings in the gun, wand, hoses and pumps. Detergents which are strongly solvent based – such as those used to remove moss or algae, are usually not suitable for pressure washers and can cause hose/machine degradation. [unless otherwise stated on the bottle]
We certainly would not recommend using strong chemicals like bleach, ammonia or petroleum based solvents
