Summit Brands Lime Out Heavy-Duty Rust, Lime & Calcium Stain Remover, 24 Fl. Oz. Bottle, Pack of 4

I’ve used LimeOut for years. I haven’t been able to find it locally and was relieved to find this package of four on Amazon at a nice value! The bottles were packaged with extra care for shipping so there was no leakage! LimeOut is the most effective, quality product for mineral stains, cruddy buildup, etc around faucets in sinks and tubs. I consider it to have commercial-quality performance, so PPE should be worn when using! Goggles or eyeglasses work to prevent direct splashing in the eyes. Waterproof cleaning gloves are a must! I usually apply some LimeOut to the mineral and soap scum areas and let it sit for about five minutes before starting the scrubbing process. I use NON-scratch 3M sponges in most cases to aid in penetrating the soiled areas. I purchased a set of thin cleaning brushes that made all the difference getting to the back of and seams of and around faucets.

For cleaning toilet bowls, this is the best product I've ever used. Coat the bowl, wait ten minutes, brush away the stains. Absolutely zero scrubbing needed.

One bottle was leaking. I wondered why the USPS had put the box in a plastic bag and I found out when I opened the bag. The box was wet from the leaking bottle.

i ended up buying this stuff to try and help get rid of the massive amount of build up in my grandparents toilet a toilet in a bathroom they havent used for years nothing worked then i tried this and sure enough i poured it all over the inside of the toilet and let it sit for a hour and used a toilet brush and the build up pretty much didnt exist anymore the best stuff ive tried in years for build up like that a real life saver and a good deal for the price i keep some around the house to make sure my toilets dont build up like my grandparents did worth the buy

melts off the soap scum and hard water when used with a eraser sponge. wear gloves to protect your skin tho but perfect for glass shower doors
