Does anyone have a positive experience in removing OLD oil stain from concrete?

Too good to be true. I see how Oil Eaters just eats oil, but it is too much for me realize how it just works in front of your eyes. The best part is that it is bio degradable and eco friendly.

Oil eater works but you need to spray it several times. Works better in the summer (warm concrete) than in the winter.

Yes. The oil stains from 1+ year ago (engine oil and rear axil lube) were removed from my concrete driveway after 3-4 weeks from one application. The concrete is now completely white and, one year later, you cannot see where the oil drips were. This product contains oil-eating bugs (I am not a biologist) and they must follow the food very effectively. The process takes time so if you are not in a hurry this is an effortless way to remove oil stains.

Recently had this problem... my gardener had to resort to gasoline & it completely removed the oily stain. I followed up with the Oil Eater a day later to remove all gas fumes. Probably not the most environmentally correct solution - however, this did work!

Absolutely. Prior to retirement, it was a staple at my parents' shop. For concrete floors, we poured full strength then used a push broom to loosen and lift the oil. For very tough stains (years old), the process was the same but Oil Eater was allowed to work overnight.

Well, on the bottle it says "Cleans & Conditions, Softens, Resists Soiling, Buffs, Retards Waterspotting, Protects Against Sun, Safe for Leather & Vinyl". So...with that being said I would think that maybe it would help clean the oil stain but I'm not 100% sure. I might be worth a try.

If the old grout is crumbly and loose, I would remove it. I did use this product over areas where the grout had receded and was uneven; it has held up well in those areas. Don't try to smooth it with your fingers, use something like an old credit card, hard plastic.

It may discolor-but if it is an inconspicuous place, it may be worth it. You can also try pure essential orange oil...and scrub hard.

This product removed cooking oil stains from my granite and those stains were over a year old. Use it exactly as directed and I think you will be pleased.

I believe so, my oil stain stayed over night the next day it was deeply penitrated, all the things that we got from Home Depot didn't work. I would give it a try or research it... it only cost $12.00 not too bad!!

Not much that can be done that I have found. You can try to clean it with a mild soap and a stiff bristle brush. Concrete will remain lighter colored for a while, as it is 'clean' since OSPHO is an acid based product, it works similar to cleaning the concrete with Muratic Acid. Most places mine has dripped have eventually evened back out to the color of the surrounding areas.

Yes ive tried to get out old stains that are about 5-6 months old. They appear to be gone but they keep coming back. I've tried everything. Even shampoo carpet. Came back.

I used this product on all wood surfaces on an 18' bridge several years ago and covered over with a premium water based stain. Still looks great today. I can see no reason why you couldn't apply an oil based stain over this product after it has thoroughly dried out. The preservative dries quickly with most of it absorbed into the wood and leaves a surface that doesn't appear to have any film or residue on it and should be compatible with an oil based stain in my opinion.Richard

YES, I rebuilt an oak park bench and treated the oak with Copper Coat, allowed it to completely dry (a week)and applied the oil sealer/ stain. Be aware, the color of the stain will be affected by the green color of the CC. Pre-test!

I have used this product for the first time this spring and have not noticed any stains on my concrete yet.

I have the light natural finish and I really love my chairs, so I don't know about the stained ones but they appear to be oiled.

So far only used this product to remove argan oil stain from granite. Good luck.

Don't know, the piece I cleaned didn't have grease or oil stains. I used it to remove the gray patina that happens to teak when left out in the elements!

Really not sure about your specific stains. But it did clean my red colored standard brick that runs about 2ft off the ground around portion of my house nicely. In past I used pressure washer and actually removed some mortar and stone! Never again! I used TSP with laundry detergent and bleach this time. Used a push broom type brush to scrub it (not really hard as I have MS and am rather weak) and it cleaned it beautifully. I also used same mixture on patio/walkway 12" x 12" , 1" thick pavers and concrete pavers, redwood deck and siding. Just slopped it on, brushed bad spots - did a great job. All I can say is give it a try, it's not expensive and may be just what you need. If it doesn't work for your brick, you can always use it for other purposes, so it's not a waste. Works great to wash walls and painted furniture/outdoor furniture. My favorite use is to add teaspoon or so to dishwasher w/detergent as booster and about 1/4 cup to laundry soap as same - you will think you have new appliances, it does such a better job. If you are concerned about phosphates/environment, then not for you. It is my understanding this stuff used to be in cleaners before new epa concerns and that's why older cleaner formulas like Spic-n-span worked so well. Not sure if true or not, I read it on the internet lol?

Before you recoat, the paint that you have on the floor MUST be in good shape. No peeling or chipping. There is a test where you take a razor knife and make an X in your old paint, then cover the X with duct tape then pull up tape and if it is less than 10% (I am not sure it could have been a little more than 10%) that comes up with tape, you are good to start prepping the floor. Sand the entire floor with 60 grit paper. You can use a electric sander. Rough up the original coating and clean dust WELL. Vacuum, Dust Mop and rinse and dry. There can be no residue on floor. Now you can apply Rust-Oleum solvent based floor coating NOT WATER BASE. I know this sounds like a lot of work but it beats the highly dusty mess from using a diamond sander to remove old coating to bare concrete. This Rust-Oleum solvent based floor paint is an excellent product and for me the coverage was more than advertised.

I have successfully used Fels-Naphta to remove stains from dry-clean only items ( wool coats etc.) Then a vigorous brushing and an airing, either on clothes line or in the dryer, thus saving taking it to dry-cleaning. Other spot removers are much more environmentally damaging. Castile soap would be an all-natural options, but did not work well in spot removal.
