I bought a new Karcher Power Washer a month or so ago and bought the Karcher soap concentrate to use with it. This weekend I had the occassion to use Simple Green with a garage broom to scrub my pool cover, and use the power washer with Karcher soap to power wash landscape timbers and decking.
The two soaps are very similar in viscosity, color, and smell. The one big difference is cost. Simple Green is $5.99 per jug and Karcher is $15.99 for a jug. $10 more!
Since the soap is added via a siphon feed after the pump I am wondering if the "official" Karcher soap is realy necessary? Has anyone had experience using other brands? Good or Bad.
