Does Clorox damage a pressure washer pump?

Yes, using Clorox or any bleach-based cleaner in a pressure washer can damage the pump and other components. Bleach is corrosive and can degrade seals, hoses, and fittings, leading to leaks or pump failure. It's best to use detergents specifically designed for pressure washers that are safe for the equipment. Always check the manufacturer's guidelines before using any cleaning solution.
