Has anyone ever noticed shoe prints after a couple passes with the surface cleaner? I don’t think this is something I did but wanted to get some feedback from the experts here.
Equipment - 5.5/2500 PW, 16” WW SC, 1,000 PSI tips
Pretreatment - around 1% mix downstreamed
Post treat - same as above
Newer concrete poured 2 years ago.
No visible signs of etching or milky runoff noticed.
This section of the patio is pretty much in full shade.
