Newer to pressure washing. Got a client from someone who quit doing pressure washing and he gave me instructions on how to clean certain parts of this ladys house (rock wall and back patio) with acid and now it has some stains on it. As far as I remember, where the stains are at is where the rock wall was starting to get green buildup. Can anyone help with giving me ideas on how to fix this?
I’ve only tried solvent mek. it worked for me

Do you have a link for the MEK you recommended? I’ve been looking and I’m not sure exactly what I should buy
Pretty much any big box store should carry it, I’ve used Sunnyside and Klean Strips Alternative and haven’t noticed a difference.
MEK is just the abbreviation for the chemical name. The brand or where you buy it shouldn’t make a difference.
it’s methyl ethyl ketone. brush it on then rinse. use cloth or hair paintbrush I’m not certain synthetic will degrade with it.
