Best way to remove Bondo and grease from concrete and pavers

by Roberta
We had a renter at one of our properties who seemed to be running a chop shop in the garage. They left a mess in the garage and paver driveway. The unit is only 3 years old and was brand new when purchased. The grease is heavily soiled in both the garage and paver driveway. There are clumps of Bondo adhered to the floor in various places. It is just a MESS! We have renters coming in 2 weeks. HOW do I get rid of the Bondo and the grease from these areas without using harsh chemicals?

I am also looking for suggestions on best method to use once the mess is cleaned up to expoxy the floor to make it look new and fresh again.

    Since I'm sure you didn't refund his deposit, why not hire someone to remove the grease and bondo from the cement and paver driveway.

    The bondo you could try a heat gun or propane torch and scrape off, or get some stronger stripper like Kleen Strip Aircraft Paint Remover and wear heavy rubber gloves. For the grease, get a concrete degreaser.

    • Manufacturers have the best guidelines for specific stains. Ask your contractor if their are any resources they can direct you to on how to remove stains on pavers.
    • Before you try any specific method, try to find the most inconspicuous area of your driveway to test the cleaning agent’s end result.
    • Always read the instructions on cleaning materials. Follow the instructions exactly for mixing, application, personal protective gear, and first aid in the event of an accident.
    • Thoroughly rinse areas after applying materials to paver stains. Try to wash materials away from plants if possible. If this is not possible, try to dilute the solution with as much water as possible.
    • If you’re trying to remove oil stains on pavers, use a granular absorbing material (resembles kitty litter). Much of the spill can be absorbed this way versus rubbing it into the paver. Rubbing could make the problem worse.
    • Use soft, nylon bristled brushes that won’t scratch pavers. If a pressure washer is used at some point, understand that this can dislodge the polymeric sand in paver joints that enables them to interlock. Some new sand could need to be added when the surface thoroughly dries.

    One option for the Bondo... is a mobile media blasting company... there are some who can do "dustless" blasting or who use baking soda... as for the grease... you can try with Simple Green but to really get rid of the automotive oil... it will take a chemical...

    I have heard that you can apply used motor oil to porous tile like Saltillo as a stain... you might have to do that to even out the color... if you cannot clean up the spots.... just blend them in.

    Bondo you will need to scrape off. You can use a blow dyer or heat gun to soften it.

    For the floor and pavers.

    WD-40. Did a leaky oil pan leave a big ugly spot in the middle of your concrete driveway? To get rid of an unsightly oil spot, just spray it with a generous amount of WD-40 and then hose it down with water.

    Soda (Coca Cola). Here’s how to remove oil stains from concrete drive-ways and garage floors: Gather up a small bag of cat litter, a few cans of cola, a stiff bristle broom, bucket, laundry detergent, bleach, eye protection, and rubber gloves. Cover the stain with a thin layer of cat litter and brush it in. Sweep up the litter and pour cola to cover the area. Work the cola in with a bristle broom, and leave the cola for about twenty minutes. Mix 1/4 cup laundry detergent with 1/4 cup bleach in 1 gallon (3.7 liters) warm water and use it to mop up the mess.

    Oven Cleaner. Get those unsightly grease, oil, and transmission fluid stains off your concrete driveway or garage floor. Spray them with Easy Off No Fume Oven Cleaner in the BLUE can. Let it settle for 5-10 minutes, then scrub with a stiff brush and rinse it off with your garden hose at its highest pressure. Severe stains may require a second application.

    Kool-Aid. Nasty rust stains on your concrete? Mix unsweetened lemonade Kool-Aid with hot water. Scrub and the rust stain should come right out.

    Baking Soda. Salt and commercial ice-melt formulations can stain — or actually eat away — the concrete around your house. For an effective, but completely innocuous, way to melt the ice on your steps and walkways during those cold winter months, try sprinkling them with generous amounts of baking soda. Add some sand for improved traction.

    Ammonia. Tired of those annoying discolorations on your concrete work? To get rid of them, scrub with 1 cup ammonia diluted in 1 gallon (3.7 liters) water. Hose it down well when you’re done.
