Pressure Washers Direct Recommended

Think about it. If you buy fish, you need fish food. If you buy a pressure washer, you need detergent.

Soap and water always cleans better than water alone. We strongly recommend the Karcher Multi-Purpose High Concentrate Detergent.

First, it contains a measuring cup for proper measurements of detergent every time.

Secondly, it's concentrated so one bottle will make 5 gallons of detergent.

Does What It Says
I used this cleaner with my Sun Joe pressure washer on my hardiplank siding and concrete patio. There was nothing that it didn't remove. I live in SE Texas and moss grows quickly on the sides of houses that don't get direct sun.

I had used the pressure washer without detergent when I first bought it but with the Karcher there was a clear difference in the ease and effectiveness of the cleaner.
