Bio Clean: Eco Friendly Hard Water Stain Remover (40oz Large). Pack of 2

Found a solution to get deodorant stains out of T-shirts, I put some of this on my shirts with a little baking soda and peroxide through them all into the washing machine and shirts I haven’t worn and had in a box to throw away or now hanging in my closet, and I am wearing them again! I did do some light scrubbing and allow them to soak. When I put them in the washing machine, I did the longest cycle I could with a pre-wash and permanent pro setting. Because I was not sure if the stains came out I hung everything to air dry I even had a couple black bras that were so stained. I was too embarrassed to wear them and they came out perfectly clean and no longer hard and crusty! This was my own test. I figured I was going to throw everything away anyway, so it was worth a shot.

This stuff works! I have tried so many different kinds of cleaners to try to get hard water stain off of my shower doors and nothing even slightly worked. Baking soda, vinegar, commercial cleaners- Nothing comes close to the results that I got from this cleaner.

An amazing product. I was skeptical it arrived and I cleaned the shower glass effortlessly. Applied the cleaner with a damp wash cloth, could instantly tell it was removing the soap scum and hard water stains from the glass. Rinsed and it was completely clean and clear. Simply amazing.

Good product and cleans up rust, and other water buildup. Be careful not to overwork the areas as it is very aggressive abrasive. Use in surfaces as directed.

Used on our car that had sat by hard water sprinklers for a month. I didn’t realize it was a problem until I couldn’t see out my windshield and a car wash wouldn’t clean it!Found this stuff and used it tonight and it came off SO EASY.It smells like mouth wash, is like a green goop, and feels gritty. We wore gloves and masks and glasses due to the skin and eye burn warnings. We rinsed the car with water, scrubbed green goop all over the windows and windshield and mirrors, and then rinsed and buffed with a microfiber towel. BOOM. Crystal clear glass!The edges of the windows have a tiny layer of hard water, but that’s probably because we didn’t scrub the edges as much, so we will do another round tomorrow to get it real clean.I’m so happy with this product and how quickly and easily it worked! Shipped within a day! I’m so relieved because everyone on Reddit was saying no matter how many chemicals they used they couldn’t remove the hard water off their cars. I’ll have to go suggest this stuff!!10/10

This worked very well! I’m impressed. It took off 3 yr old soap and hard water and lime off of my shower doors and floor. I barely even had to scrub. Highly recommend

I use it to clean shower and sink. It works perfectly against hard water stains.

My experience with Bio Clean began in the summer of 2002. As a real estate agent in California I had the good fortune to list two residential subdivisions for sale, totaling 173 homes. These homes were all about 12 years old and had been purchased, while still under construction, by a very wealthy off-shore investor, who proceeded to rent all of them, as each was completed. Sadly, little or no maintenance was done on the homes and all required extensive rehabilitation before selling. Deep cleaning was the first requirement - and Bio Clean saved the seller literally thousands of dollars! Window glass on every house, wherever exposed to sprinkler over-spray, seemed hopelessly stained and fogged over, apparently requiring replacement. One of the rehab contractors came to the rescue and demonstrated how a little Bio Clean on a damp cloth would clean off the extreme staining, leaving the glass clear and sparkling! The technique was simple and never varied and I estimate that at least 350 windows were saved from what seemed to be terminal staining and discoloration. The work was done by a couple of inexperienced young people, using only this product, soft rags and water.This amazing experience became widely known in my real estate office and the product delighted scores of home sellers when given BIo Clean, or referred to it for cleaning fogged, dirty windows, bathroom fixtures, shower doors, kitchen faucets, sinks etc.Upon my moving to the midwest 10 years ago - where basements are common - and the windows often deeply stained, the product quickly made me a popular neighbor. I shared (and demonstrated) this product, restoring basement windows which they had long thought needed replacement, “some day”. Over many years, I’ve tried about every product offered in retail stores for the purpose of removing tough calcium and other stains - without real success. I've found that Bio Clean works perfectly in every household and automotive task appropriate for its use.
