somewhat overkill, but since I do my own painting I always have plenty of PPG DX-330 grease remover around, that stuff cleans just about anything under the sun. it's especially effective for motorcycle chain wax, which can be a B..... to get off otherwise.

Oil Stain

Auto Zone sells a drip pan that just about covers a 3X4 area.

I use oil-dry from any auto parts store, or kitty litter works good too, only for the initial, really wet spills. I use gasoline and some rags after that. Like Willy's says, if you've got a natural gas, propane, or fuel oil water heater, be sure to have the garage door open to prevent those not wanted explosions.

If you want it really clean, use muratic acid, but it will etch the concrete and your feet, hands, and lungs. You'd need knee boots, rubber gloves (thick) and a respirator for this stuff.

I just leave mine alone til it bothers me a bit. I figure it is just going to get dirty again and I don't need a yuppie type pretty garage floor anyway.

Thumbs up

I've used trisodium phosphate to remove just about everything from concrete, including rust stains from washing an old car. It's available in hardware stores and isn't nearly as dangerous as muriatic acid, kerosine or gasoline.

Where are the stories about using Coca-Cola (Pepsi won't work) and laundry detergent?? Perhaps check the forums on Good Housekeeping. LOL
So far the cheap solvents and cheap kitty litter work for me.

Oyl Staynes

Firstly as your Lord and Saviour, my deer Children.. Ceement is a nasty Alkali...

Acid ruins Ceement.

What works good on cleaning Ceement is the application of another alkali - to etch out the oil and not ruin the ceement.

I use about 250 grams or 1/2 lb (for the backward Emerikens) of sodium bi-carbonate - and I usually toss in a good heaped spoonfull of sodium hydroxide (caustic soda) and I mix it into a watery kind of pancake mix then I pour /paint it on to the stains and then I let it sit......

I then re-apply water to the painted on patches of drying out mix..... and I rescrub, and I repeat this process several times daily over a few days to a week....

This emulsifies and leeches out the oil that has penetrated into the concrete.

Just keep your critters from walking across it...... and then when your happy with the result... hose (low pressure) and scrub away the mix.....

A second reapplication may be necessary for cosmentic reasons... but aside from that...

It's pretty thorough and it works good and there are no fumes or deadly (flamable) vapors....




*depending upon the size and amounts of oyl staynes, (good for about about ~1m2 or 4 - 8 square feet )

I will third that, bad stains twist and turn and then I sweep up and return the used stuff to a seperate barrel and reuse till saturated and start the new stufff goes a long way, I sure get upset when my boy doesn't have the time to do the same when he finishes working on his truck. I have used some blue cleaner from work that is the same as Castroil blue cleaner and it works good with some scrubbing but more costly. Ed ke6bnl

Ditto - kitty litter and the twist.

Try WD-40 for stubborn spots. It works!

oil on garge floor

Muratic acid will clean just about anything but be sure you wear gloves andwhen ya wash it off you have to dilute the water with vinegar to stop then acid process form keep on going and it will make the concrete whiter than the rest so make a clean sweep over the whol floor so it's uniform ya know not safe for inside the city so don't get caught using this product or it will be a haevy fine but it will cleann anything you got and the bubbles is it working on the oil and also eating thre top layer of concrete if not carefull!!!
