You would think that if they knew anything about selling, they would show other nozzles, good point.
Rinsing anything off a hard surface is not too hard, probably could do that with a garden hose since the stuff did not soak in, leave it in there for a week or month then do a test and see how you do. Kind of hard to use the pressure washer in the kitchen, there would be a lot of water to clean up. Time for the Sham Wow!!! hahahahaha
I contacted that company a few times, the owner and a couple of the salesmen are real A**holes and jerks in general. Like the pressure/used car sales techniques work anymore, not on a lot of us. hahahahaha
Supposedly they have a good steam machine like what the gumbuster guys use but better. I would not buy from them no matter how good their machines are, they are A**holes to deal with for just asking questions and getting info, I would hate to see what you would have to go through to get something fixed under warranty. Wow.
