First i hit the ground with a 1 to 1 ratio of water and pool chlorine 12.5% with a good squirt of dish washing liquid. Let that sit for 5-10mins. Got a 20 inch surface cleaner on wheels that does the bulk of it and then hose/wash it down with a turbo head on the wand. Got myself at 14HP 18L/M 4200psi machine for $1500 and another $500 for the surface cleaner. Have spent another $100 on quick release attachments and high pressure ball on off toggle. Saves turning the machine on/off to change things over etc...

Pretty close to my old mix.. On 3 litres of mix used to also add about 1/2 a cup of trisodium Phosphate which was fairly good to also get rid of grease and oil stains on concrete that used to work pretty well.
