First of all, I'd like to say hello to everyone and thank anyone for any help they can provide me.
My name is Amanda. I recently started up a pressure washing business after going to get certified to clean kitchen exhausts. I have a 3300 PSI 250 degree 5.2 GPM unit on a 16' enclosed trailer with a 225 gal water tank, hoses,... blah blah blah... not really important I guess... I AM also insured with 3 million gross insurance (I know that's a biggie).
Anyways... to say the least I really am VERY new to this whole pressure washing thing and aside from doing the kitchen exhaust cleaning (which I feel confident in after the course/certification) I am not very knowledgable (yet) on the other aspects of pressure washing, although I truly want to learn the correct ways to do things and of course in an efficient manner. I have done a lot of searching on the net for tips etc, but I have really had a hard time finding any answers for how to correctly clean limestone.
I also own a window cleaning company which I've had for almost 5 years now and a recurring residential customer of mine just recently asked me about pressure washing her 1 story house that has some limestone walls/walkway/patio (the majority of the house is brick, but she's not concerned with getting that cleaned right now).
From what I've gathered through searching I should use low pressure for sure, and I read a little about use SafeRestore as a possible chemical, but other than that I really don't know much else. :( Like I said earlier, I definitely wanna learn the correct way to do things so I don't damage her property. Could anyone find it in their heart to help me out with some information on this please? I know I'm a newbie, and I probably have a lot of "dumb" questions, because I just don't know yet, but everyone has to start somewhere. So please be nice :) and I'd like any info that y'all are willing to give. Thanks for your time.
