Stone & Tile Intensive Cleaner for Travertine & Natural Stone, 1-Quart | Marble, Limestone, Travertine, Granite, Slate, Ceramic, Porcelain Tile

This is the absolute best cleaner for natural stone! I use it once a year to do a deep clean. It is a little pricey, but the finished product makes it completely worth it for annual maintenance. Keep in mind that this is an 'intensive cleaner' that will strip the color out of the stone. If you want that luscious, wet-stone look, you must follow up with the Black Diamond Color Enhancer Sealer. Taking this second step gets the stone looking beautiful. I highly recommend this product if you are willing to do the two-step process. However, if you are looking for a simple cleaner and don't want to do the follow-up sealing step, DON'T buy this! Your stone will end up looking dry, dingy, and completely washed out. **The odor is very much like painting, so expect to smell a chemical scent. **

My pebble shower floor is only about a year old, and nothing I tried would get it truly clean. I’d used several different cleaners and spent a lot of time scrubbing with little success. With this cleaner, I let it sit for just 10 minutes and only needed light scrubbing. The difference was obvious! It was by far the easiest time I’ve ever had cleaning this shower floor. Highly recommend!

First let me say that I bought this to clean some really nasty grout in my home. We purchased our new home a year ago and I suspect the grout had never been cleaned in the ten years since it was built. It was pretty nasty. Unfortunately this is not the product I should have purchased for that job. I called the manufacturer and discussed my situation with an extremely helpful man and he told me about a better product, their Ultimate Grout Cleaner, which they have for grout cleaning. He also gave me some very good advice about taking care of my ceramic tile. So even though I purchased the wrong product and obviously didn't get the results I was hoping for, I did get clean floors and so I'm giving this product four stars. The product works well for it's intended use, cleaning dirty floors, but if you want to do a better job on your grout, purchase their Ultimate Grout Cleaner.

I ordered this for my travertine shower, but decided to use it on the shower floor at our cabin, which is plastic, I think. I was so very surprised to see how it cleaned. Very impressed with the product. Next is the Travertine. Easy to use... no fumes. I did use a brush and scrubbed a little.

It didn't remove all stains.

Using everybody else's reviews as a guide, I took a chance and purchased some Black Diamond Stone & Intensive Cleaner for my travertine floors. I have honed travertine with chiseled edge and wide grout lines. The floors are beautiful, but don't let anybody fool you they are a lot of work to clean. Part of the issue with natural stone is the limited cleaning products available. The chiseled edge and wide grout lines, makes it more difficult. Mostly I just steam clean the floors and use products like Bona or Formula 409 Stone and Steel Cleaner, but every now and then I do a deep clean. I started by pretreating some of the dirtiest grout lines with a long-handled scrubber and some Black Diamond solution, followed by loading my Koblenz orbital scrubber with Black Diamond solution. I've very pleased with the outcome. I have paid 2-3 times more for other cleaners and the results from Black Diamond are equally as good, if not better than those cleaners. The travertine is brightened as are the grout lines. Are the grout lines completely clean like new, no but they are pretty darn clean. Part of my issue with wide grout lines and chiseled edge is that the liquid solutions pool in the grout lines and if that liquid is dirty, well there you have it. If I could just find an orbital scrubber with extraction device, that is not priced in the thousands of dollars, I would deep clean more often. As it is, I scrubbed the floors, then used a wet/dry vac to suck up as much cleaning solution as I could. I then went back over the floors with plain water in the orbital scrubber to rinse, as it says on the directions of Black Diamond, followed by extracting the water with the wet/dry vac. I probably could have rinsed a second time as I used the cleaning solution very generously, but there are only so many hours in a day! The grout lines by the front door could probably benefit from another cleaning, as that is a high-traffic area, but they are cleaner than I have seen them in quite some time. There are a few dark spots where liquid has pooled, but that is the nature of this beast or chiseled edge tile and wide grout lines, and not a result of Black Diamond.

Used full string on a paper towel. I had to remove the foil. Top, should I send this item back? Black Diamond is usually a good name. This one doesn't seem to be that good at all. I just got new tiles

Left side of photo is clean and right side is dirty. My travertine floors are cleaned every week but the dirt is too much with our dogs and daily traffic to be cleaned with just the average vacuum and mop. I have an oreck orbiter which is a MUST for everyone who is OCD, owns expensive flooring, and/or owns animals who live a better lifestyle than you. I too bought the green bristled brush for the oreck and sprayed this cleaner with a lawn and garden sprayer onto the floor and then proceeded to clean with the orbiter. Because I forgot or rather blocked it from my memory, my husband claimed he had a 10:30AM tee time. After a few homicidal thoughts and counting back from 10, I did a really quick swipe of the piece of floor I just sprayed. I then had five minutes of wait time for the cleaner to sit which I used to stare at said husband with a “who the hell invented golf because I am going to make it a sole goal to haunt this person” look. After a quick wipe up and a quick dry, I assumed I would take up the chore again when my golfing husband gets back from the 19th hole. I really did not expect anything because I felt I did a very quick, poor job on the one spot. After about 4 hours of dry time, I could not believe it. The travetine and grout look great. This will be my go to when I need the deep clean but not in the mood to use the gorilla diamond polishing pads. The diamond pads are great to use to get the shine back on travertine floors. Husband is still playing golf now so I will report back if anything changes or if he doesn’t come home and need a new husband.

Satisfied with the product . Removes dirt and oil well and gives a nice feel to the feet while walking on it

Utiliser pour nettoyer un carrelage en Terrazzo extrêmement sale après la pose, le carreleur ayant été peu soigneux. Le produit est très efficace et pas agressif. Bien respecter le mode d'emploi qui est en anglais

Great product! It does not have the typical strong chemical smell you’d expect from an intense cleaner. After applying, built up dust and grime got left up in five minutes, and it’s pretty easy to wipe off

Didn't work!

Just follow the instructions on the plastic gallon , and spray the water with this liquid on the wall tiles in the shower area and use a hard stainless steel brush , you will notice immediately the tiles will be as new from the factory. Use gloves and cover the eyes with safety goggles. It's very good liquid and very effective.
