In the past year, my Disco has horribly marked it's territory in our new house's garage. I really need to remove the stains in the concrete.
From past experience, I know kitty litter is only good only if you use it right away when you have a haz waste spill.
Does anyone have any other cleaning solvents or tips for getting concrete clean again?
Thanks in advance!

 

I believe Tractor Supply CO has a muriatic acid based concrete cleaner that works great. Make sure you get a mask and plenty of ventilation though! Home Depot has a ZEP driveway cleaner that will work too.

 

Good topic, I've been wondering this same thing. I'd like to try and find a product to follow up with that will help protect the driveway if possible

 

For garages you can do the epoxy coating but for the driveway I would do a masonry protectant.

 

X1 ............. I would recommend epoxy after the oil has been thoroughly cleaned up.

Also ArmyRover did his garage floor with grey epoxy recently I seem to recollect so PM him and get some idea of product recommendations and costs per sq ft/sq yard.
