I’m the maintenance guy for our facility and I’ve been enlisted to wash our building! It’s a combination of metal siding, brick and concrete. I’m new to using pressure washers the “right way”. I’ve been trying to do my homework and have read up on the web about using an x-jet nozzle. The company owns a Stihl RB 600. I know it’s not the best but it’s what the boss got back in the spring, so it’s all I have to work with. We recently purchased a X-jet M5 after I showed them some videos on the web.
I guess my question is… Is there any special considerations I need to take into account with the metal siding. Yes, it is metal not aluminum. I’ve read on some metal building manufacturer websites about just using like 1/3 cup of laundry detergent per 5 gal of water and use that for the “wash”.
I greatly appreciate any tips or info. I just don’t want to be the one to mess the building up and end up having a really expensive paint job!
I’ve tried to upload a pic of the building, hopefully it shows up.
