Learned a valuable lesson yesterday. Safety First... pressure washing requires safety glasses. I got some of the detergent in my eyes and thought I was going to go blind. It is very much like flash burn from a welder. My right eye got the worst of it and I struggled with it all night long. It's still vary irritated and watery this morning but not nearly as bad as it was. If the sun comes out today I'll most likely need sun glasses.
