I’m bidding a fence staining job tomorrow that also wants the driveway and pool deck cleaned. Looking at it on G Maps it looks like exposed aggregate. I have cleaned it before with the SC and my 4K/4GPM machine I always get the mold, dirt etc off but to me it never really looks “clean” the way creamed concrete looks after cleaning. I am just interested what if anything I can do get a better looking clean on exposed aggregate. I searched but didn’t find anything specific and if I watch one more you tube of a guy using a SC I’m going to go blind. BTW, how about them Cowboys!
