The majority of my business is cleaning up food grease on cement. I am wondering if anyone else does this and if you use anything else other than dawn dish soap and 200 degree hot water. This works pretty well, but I am curious as to if anyone else does something different.
I use a sodium metisilicate based cleaner to remove animal fat grease, and a potassium hydroxide based cleaner for automotive grease. Either of those, hot water, and my surface cleaner.
for tire marks can't beat Dominion Resto. Prod. DR-60 www.domrest.com also great on drive throughs and eating area where grease of all kinds can be found. I never leave home without it.
weathershield,new cement is called GREEN. It is not fully hardened. Be very carefull not to do it damage. Go one size bigger with your spray tips. Try and sell a sealer job to the customer www.v-seal.com
Tell the customer that you can greatly improve the cement but not get it perfect untill it has cured a min of 90 days.
Sounds like a driveway or pool surround?
I would use a limonlene and truck wash mix.[same as my house wash]. If you do use your mix it might not do much on the tire marks and you need to add a soap[DAWN DISH SOAP] TO KEEP THE DIRT FREE FLOATING so it wont re-stick.
