If it is just spots of oil, tire dressing etc, you might try spraying them with A2Z and working it in with a brush. This worked really well on my drive way on year old stains.

Let us know if you try this and if it works for you. :)

Where do you purchase A2Z?

I`m sorry Rubatrack ... Eagle One A2Z All Wheel & Tire Cleaner.

Its available in many automotive shops, even Walmart. Look for an orange spray bottle.

Good luck!

Try these guys for any concrete or title needs. I had a black slate hallway years back and they helps me get it cleaned and sealed up. I have never forgot about them

Also, you might try Castrol Super Clean All Purpose Cleaner, in a purple container. I`ve used this too and its very good with cleaning oil and grease. Same method, brush in, leave a while then rinse.

Good luck!

I use mineral spirits (paint thinner) ....
Poor on and wipe up with a paper towel.
Sometimes I follow up with Simple Green and hose it off ... be careful though cause it can damage grass and shrubs.

Be double careful if you have an asphalt driveway - the oil cleaner will damage the asphalt.

I use kitty litter to soak up the oil/solvent mix and then wipe dry with paper towels.

Yeah,
Mineral spirits (paint thinner) on concrete only ... Thanks!

on any concrete use muriatic(sp) acid it works wonders! they use it when acid washing concrete pools! I usaully cut it 1/2 acid and 1/2 soapy water solution.... use a old broom ...and brush it in ... let it sit for 5 mins ... come back with a power washer ... and it comes out cleaner than the day it dried!

Where do you buy this acid from? A home improvement store?

Thanks

Mike <-- always happy to try something new!

Will the muriatic acid work on asphalt?

Just tried some A2Z I had on my driveway...when the water dries I`ll report how it looks. Thanks for the suggestion!

Muriatic (Hydrochloric) acid is the main component of the `etching solution` that you use when you are applying epoxy coatings to concrete. You can buy it at Home Depot.

I am not sure that it is effective for removing oil and grease tho. I just did my own garage floor with "One Part" epoxy coating (from Home Depot) and got better results with the oil removal solution where oil was concerned. It does a great job on rust stains,etc. tho.

The down side is that it will definitely `etch` the surface of your concrete and you may not want this. I would stick to a good oil/tar remover if it is just oil stains you want to get rid of.

I hate to float my boat here again but if you check the link I attached on my first post you will find what you need from experts in the area. These guys are not guessing its there business!!

You may be interested to know that "Muriatic" was the name given to hydrochloric acid during the 1930`s when it was used by Murray Goldstein of the infamous `Goldstein` mob. The gang members would soak their fingers in acid to remove their finger prints. This practice never gained wide acceptance due to the inevitible loss of digits when too much acid was used.
