I had to go finish washing this building today because the person they had doing it was destroying it with a pressure washer. The contractor doing the building remodels was there watching me. He told me there was no way I was getting it clean with just my little electric 60 psi pump. I told him if I didn't get it clean he didn't have to pay me. His jaw was dropping about 10 minutes into it. A pressure washer and a low pressure sprayer both have there place. Knowing when to use what is where us as professionals can make the difference.
It was such a small job I didn't measure I just poured some in and added a few squirts of Dawn and sprayed it, It worked so I left it alone. I only made up about 7 gallons total. Probably around 5 or 6%.
