My black grout has turned grayish-white over the years. Will this remove old cleaning products and restore the dark color?

Would try with that v shaped o cedar grout brush Might have to let sit reapply . Wait for grout to dry to assess

I would try a Mixture of Proxide and Water. Proxide will help keep the tile White,as it Cleans. For the 21oz bottle Go 4oz of Proxide and the rest Water. With the micro fiber you will see more dirt come off the Floor. Hope this works for you.

yes, it cleans grout great! however, it kills the bacteria and powers out gunk - it won't turn it white again. grout is porous and can stain from mold, etc. to get any stains out of it, it's best to use a bit of bleach on it after you get the gunk off. once it's clean and dry - use a grout sealer on it - and the next time it gets dirty, it won't stain the grout.

Yes. It works on most stains. I say most, because I think the only thing any cleaner has a tough time with is grease. But this works better than any other grout cleaner I've used.

I had read to simply use oxygen bleach so I mixed this product with water and nothing else. I had tried floor cleaners and bleaches but Bio Kleen restored the grout color to the original shade, based on tiles between the cabinets and fridge. Hope this helps you.

Good question...so good that I don't have the answer. I will tell you this - there wasn't ONE word of exaggeration in my review..my grout was sparkling, like new white grout..there's the key word "white". My other bathroom has light tan grout. Zep got the stains up but did NOT BLEACH IT. since I'm only talking light tan, I would not use that as the green light to use it on your colored grout. I just looked at my bottle and there's a customer service line for questions like yours...I'm sure it's on their website too...Yeah, I know, you where hoping for "real world" results..well that can be you once you use Zepp then brag about your beautiful floors!

If you use the whole system and clean all the existing grout as well as scrape it with wire brushes, it will be clean enough to use the product Makes it look like new but maintenance is required and it will have to be redone (maybe) semi-annually.

Yes, I have used it many times on my colored grout. I have both a beige and darker mauve colored grout, 1000 Sq. Ft. and have never had a problem.

I would say "yes" if it's a clean app.of grout. So worth a try. I've tried many grout cleaners and this is the best so far! This will be my "go to" grout from now on in.

this product works great. I have pale cream grout and it did fine. You may however try a small patch under something to make sure.

Yes! I used it in my bathroom with great results. My tile and grout look brand new. I've used bleach and didn't get the results that I got with this product.

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.

Yes it will clean old stains well but you must pretreat the stain first let it soak for about 30 minutes and clean as usual if that doesn't work retreat until you nolonger see the stain it may take several treatments to clean it up depending on how long the stain has been their. Good luck on your success in cleaning this.P.S. I would be lost if not for my scruber it was the best buy I made great also on ceramic tile flooring cleans grout to a new finish .

I used this product a year ago. I cleaned the old grout with a small brush first but I did not remove any old grout . It worked great! A year later it still look like new.

A little. It loosens some stains. But its no fault of the machine. Grout is pourous; it absorbs. So the only way to really clean grout is manually with a commercial cleaner, or with bleach and vinegar and stuff.

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.

Kimo, I think the machine does a good job with the grout cleaning, but I do have one extenuating circumstance. I purposely used dark gray grout when we had this tile installed. This is a high traffic area plus where we feed two dogs. When I finish cleaning the floor all of the grout lines are consistently damp which shows they have been scrubbed. I'm satisfied. Hope this helps. Judy
