Bio Clean Hard Water Stain Remover 6-40oz Pack) | Bulk Value Eco-Friendly Cleaner, Removes Hard Water Stains, Soap Scum & Mineral Deposits, SPECIAL

This worked great for water/mineral deposits in my shower. We have well water. The custom metal, stone, and glass shower is 4 x 4 feet. The shower and well are seven years old. Water testing did not reveal any minerals out of the desired range, but we were unable to get the mineral deposits (scale) off of the interior of our shower with CLR, Comet, Bar Keeper's Friend, Soft Scrub, Ceramabrite, Limeaway, or vinegar. All three brushes worked well except for in the smaller corners and crevices where I had to use a very stiff, nylon hand brush the size of a toothbrush. I mostly used the larger of the three brushes, and by the time I was done, the bristles were about 50% shorter, but none had fallen out. The cleaner has a nice, but strong, minty smell. I used the cleaner and brushes on glass, grout, caulking, metal, stone, and plastic. It took the paint off of the screw heads holding the custom metal, shower door frame, but the frame itself was not damaged. It also took the paint off of the metal drain. I was surprised that it didn't scratch the plastic or metal parts of the shower head, cord, or control knob. It did not damage or scratch the grout, but it did pull up some of the weaker areas of caulking. Initially, I thought it removed/damaged the finish on the metal shower frame, but I just hadn't thoroughly washed off the residue from the cleaner. I'm very happy that I found a way to get rid of those deposits.

This is magic stuff. I have tried several well-known products over the years to remove well water from the outside of my window where the sprinkler hits. Our well water is very hard and this is the only thing that works. Thrilled to have found this product.

Product worked perfect for the glass door on my oven. All grease spots are gone and the inside glass looks like new. Also took off the spilled stains on the oven floor. The glass stop stove looks almost new. Works better than the products for glass top stove. I used the same scrubber that is suggested for glass top stoves. My 30 year old laundry top looks much better after using this product. There are very few stains left and it looks great. The faucet is shiny looking like new. My kitchen sink looks better too and marks from my pans aren't showing up every time I put the pan in the sink. The above items get a 5 star. The glass shower doors get a 3 star. The glass shower doors look better, but there are still a lot of hard water stains on the door. I have used 5 applications on the doors and just can't get it totally clean. Same with the bathtub faucet. I will keep trying as this product has a better result than the grocery store products I have used over the years. I use a lot of vinegar for cleaning and this does do a better job on the shower glass doors. The tracks look wonderful after using this product. I will try this product on my sliding doors and tracks once winter is over. I expect a good result.

This is about the third review I've written in the last 8 years, but I love to read reviews, so I'm writing it for those people! WOW! This stuff is incredible! I just moved into a house that is 150 years old, and has been inhabited by old people for the last 60 years. This house was clean enough, but not deep clean. I am a clean freak. Before taking this top picture I had used comet, comet soft scrub, some green natural stuff, and scrubbing bubbles, and whatever else I had lying around. I just kept trying things. In fact, the top picture was taken while scrubbing bubbles were in it (so the white foam is those bubbles. Imagine that sink being even dirtier because of what those bubbles are covering up, and the scrubbing bubbles also did nothing). I worked on this sink with these drill brushes and solution for about an hour. Nothing else in the house took me that long except this well-used OLD kitchen sink. House was last remodeled over 50 years ago. The sink now has a soft silky feel to it, and it looks SO much newer than it actually is! If you are thinking of replacing sinks or tubs because of hard water stains, I would use this first. It is worth trying. Even with the length of time it might take, it doesn't exhaust you because you're not scrubbing with your arms, you're cheating with the drill.

Wow! Wow! Wow! I've been putting off cleaning our shower glass because I know what a pain it can be. Well fast forward and here I am one year later (maybe 2) trying to clean the glass. I thought for sure this stuff would need to be scrubbed and scrubbed and scrubbed...but nope! Bio-Clean's Hard Water spot remover is AH-MAZING!! I used an old sock rubbed it in using hardly any pressure and I could feel the rough spots disappear as I rubbed. The harder caked-on spots took a little bit more rubbing and when I say "little bit" I mean just a little bit, I didn't even break a sweat. I rinsed with warm water, dried the glass with paper towels, and done!! I tried using my drill with the sponge attachment but that was even harder to do than just doing it by hand (the drill is kinda heavy). Any-hoo, see my pictures and video attached, this stuff is a game-changer for sure!! I used it on our brushed nickel handle and it was perfect for that too! I will always buy this from now on to clean hard water spots/stains!!!

I have a shower door with years of hard water built up (white stain). I used a towel with the remover, and it does the job of cleaning up the white residue. HOWEVER, the hard water stain marks remain. I have applied the process a couple of times, and the stain remains. Overall, this product removes the heavy buildup, but it WILL NOT make your glass clear as new.

We use BIO-CLEAN Septic product and have been really impressed with what it does; so I bought this for the bathrooms. Works great on the tile and grout on a shower I installed 10 years ago. We have pretty good water here in the Western side of the PNW but there are times it does get a build-up on things. Brings back the shine and smoothness to the porcelain tile and basins. I would like to see an applicator that actually keeps the goop on the tile instead of getting centrifugally forced up the brush though, tough to spread where needed on the round flat attachments.

Does not work on any kind of stain. I even let it sit for awhile and still no luck. Save your money.
