Black Diamond Stoneworks Stone & Tile Intensive Cleaner: Concentrated Deep Cleaner, 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. **

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.

I purchased this because my patio (limestone) had become really dirty. I mixed some up in a spray bottle and sprayed down the areas that were the dirtiest. I waited a couple of hours and then sprayed it off with a garden hose. In all honesty, I felt that it could have done better but that night, we had torrential downpours and THAT did the trick. So my advice would be - spray this stuff down before you know you are getting a heavy rain and let the magic happen. You could use a power washer with the fanned out attachment if you have one. I'm happy with my results.

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.

I purchased this for water stains from plants kept on the tile around my jacuzzi tub. It only helped lighter stains. Even scrubbing with a brush as the bottle suggested, it did not remove deeper stains. I may need to try several times. On a positive note, I used it on the tile flooring of my shower and it brightened it up.

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!

This product did nothing for our travertine tile floors. I wasn’t expecting miracles but atleast some dirty water or residue after scrubbing with a brush…i tried 3 times in different locations. Followed instructions each time though the third time I just poured the concentrated solution directly on the tile to see if that made a difference and let it sit for an hour. Absolutely zero change and wiped clean again! The floors look very dirty despite vacuuming everyday and mopping multiple times a week. Was hoping this would lift some of the dirt but unfortunately it didnt. Smells nice so I’ll use it for regular moppings to not waste the product.

We have a porcelain floor imitation wood and the dirt got stuck over the last 5 years We did a first round and we are almost at original color We need one more round and we are brand new

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.
