I have found that detergent is rarely necessary
After the purchase of my 2400 psi, Honda-powered (6.5hp) washer, I did a
little experiment on my deck in preparation for staining.
I bought a gallon of expensive Deck Wash concentrate. The jug pictured a user
with a little, electric-powered washer - appropriately so.
I treated half of the deck with the deck wash solution and the other without
it.
Conclusion: At 2400 psi, detergent is irrelevant.
The situation is no different at 1750 PSI with an electric.
