Can you use this on stained concrete

not sure, but this is similar to "bowling alley wax" and it would definitely make the concrete surface super slick if it got wet. If the stained concrete is really porous, it may be really difficult to polish properly.

Sorry. I don't know. Haven't tried it on yellowed grout. My guess is it is not the product for that. This product seems to lift the dirt/stain and yellowed grout may be yellowed throughout due to age. Probably need some sort of bleach or acid. Perhaps a wood bleach which is safe and might work.

It works on concrete floor that was stained/painted. Have not tried it on totally porous concrete.

I'm sorry, I don't know about use with stained or finished surfaces. Works great on bare wood.

If so I have not seen it. If your grout is really dirty then you will need grout cleaner for that. It works on very mild dirt and stains (i.e. food) in the grout, but not on really established stains. Hope this helps.

I've only used it on concrete; so, I guess, I can't really answer your question...

I have not done this, but from my experience using it for wood, if the underlying surface is flat and smooth, then it should work.If the concrete has a rough or dimpled surface, then it will not work well at all. I would use a wire brush in that case.

Perhaps if diluted. I personally use this for very tough stains (clothing) and it works, even if the stain has set in.

I haven't tried it on stucco so I don't know. It claims to work on concrete, etc. If you have green algea it should be easier to clean than the black stains. I was able to remove these stains on wood clapboards with a 50-50 bleach water mix, but you'll need to scrub...

I only used it on concrete. Sorry, I cannot help. If your car has surface rust, then it might be OK to try anyway as it seems that you might be needing a paint job soon.If you have surface rust, then you have rust under as well.

This will not work because it will gouge the floor. You may want to use a razor blade style telescoping floor scraper to get the heavy stuff and a solvent to dissolve and remove the rest of the glue. Since you want to stain the concrete you may have to use a solvent to get all the residue and then use a floor machine that will grind the concrete surface so stain will work. You may be able to skip the solvent if you rent the proper floor machine. Good luck!

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?

It does in some circumstances. On some it leave a white spot on the concrete. It removed iron, so if the stain has not been there too long it can help. Otherwise you get a white spot with a stain in the middle. I use it to remove rust from many things. Well worth the cost for what it can do for you. Stains in sinks and stuff.

Carol, If I understand your question correctly, SOYGel is designed to remove topical coatings from wood and concrete. If your concrete porch is stained, SOYGel will not remover the stain from the concrete. There are very few coatings we have run up against that the remove will not take off. Best thing you can do if you are not sure is to call our toll free number (800-538-5069) and request a sample of the product to test first if you are not in a time crunch. Also, I'm not quite sure what you mean by "thick spide". - Hope that helps Carol (Jason)

Have only used it on the grout. It worked really well on stained and mildewy grout.

Safe for painted and unpainted surfaces, metal, stucco, stone, grout and asphalt and will not etch concrete. You can simply spray it on, let it soak, rinse it off.

I used it yesterday and got some on my concrete. I left it and we had a storm last night and there are no traces of it. So in my opinion it does not stain concrete.
