I'm looking for recommendations for foaming soap to be used with a pressure washer on the undercarriage. I have a 3300 psi washer and it has a soap input and foaming nozzle. I've washed with just plain water and not too satisfied with the results. I know to be careful around grease fittings and greased bushings. Any other advice?
