I'm trying to find ways to not having to constantly redo my BR due to moisture causing black spots on grouting, will this help?

No, I had to re-grout my shower 3 times I one year due to black mildew and deteriorating grout. And that was with very highly rated sealer. I will never have a tile shower again.

It's hard to know. You can only try. This is a good product, but you must have a moisture problem that needs to be addressed before anything can work successfully.

I think it might do very well at that task. I suppose it depends on the type of grout it self, although I have to guess that grouts might be pretty similar in composition. I'd try mixing up a solution of oxi and hot water (oxi works best with warm/hot water) and scrubbing the grout with that solution using a small brush. Do just a small area initially to see how well it works, and if the mixture damages the grout at all. I've used grout cleaners in the past that were so strong that the caused the the grout to fall apart. I would rather has dirty grout than NO grout, you know? Oxi might just be a perfect grout cleaner, although I've never used it for that task.

Removes surface dirt, but doesn't "scrub" grout completely clean like a toothbrush and elbow grease. But once you do that, would probably keep it clean.

No! This is to restore more less raw marble. You'd ruin your floor. Buy a grout release product. That's their purpose.Or.....just use a damp towel and elbow grease

Tough job, I own a cleaning service. I don't do much post remodeling work, it is difficult. Try a huge damp sponge. Keep rinsing. Again, I am not an expert on this form of cleaning.

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.

Yes it would, I happen to have a new self sealing grout that is very stain resistant, however I do clean up drips immediately. If I leave the drips, even the stain resistant grout will show a very slight discoloration. I imagine an unsealed grout would stain quickly.

Yes. I usually just use water but baking soda and water may be even better. Start with a lower concentration and don't leave it on long. And a day or two later redo the same spot. Good luck!

Please do not mix with grout! It is intended to be used after the grout has cured for at least 48-72 hours. In my opinion, most of the products that claim to protect grout from being stained are just gimmicks. As a tile contractor with over 25 years of experience, my preferred method for grouting would be to use Custom Building Products Polyblend cement-based grout that is mixed with water. If you want maximum protection, try my Epoxy Bond. Why? Because it never needs to be sealed, is 99% waterproof, and will not crack in corners like regular grout.

Agree with posted comments. We have black Richlite counters which are porous and stain easily. Osmo oil has worked better than the installer's attempt at sealing. Make sure to apply it with a lint free cloth. If applying two coats be sure to wipe down between coats with tack cloth and allow it to dry completely. No, it does not leave a residue like mineral oil.

I would still be using it if I hadn't had the bad experience with my wide, light-colored grout used for my tile. It stained it. The fragrance was wonderfulto me after using it to clean. As I say, when I used it on the floor I freaked out. The grout turned black.

I have the same problem. Like you I tried sanding. It helped a little but not very much. You might just want to resign yourself to living with the stains, not the end of the world. I suppose you could get it replaced but that might be a big project. Wish I could be of more help. To prevent the stains from getting worse, use John Boos Mystery oil regularly, it's good stuff. You can let it sit overnight which will help it get absorbed by the wood.

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.

It may depend on the type of grout you have. I have one type of grout that resists everything, even the steam. The steam seems to do a good job on the other light colored grouts that I have.

Yes. I used it and had great results without having to get down on my knees to do it. Once you get the grout clean I would reseal it (two coats) and then use a solution of hot water and biokleen in your regular cleaning to keep it clean and fresh.

Depends if it is dirt or if the grout is stained. Won't lift staining. I use a coarser pad [not the usual terry-cloth].

I haven't used it enough to know this problem. I suggest to try a little ammonia. Again I am not sure this is something that was suggested to me due to tile flooring losing it's shine. It just might help with the clog.
