This product is purely incredible. After using some wire-like brushes to get off any surface rust, I applied this spray. It is amazing how much of a difference this product makes and also reduces my anxiety about the rust spreading further along.
We have a VERY high iron concentration in our well water at home and it ends up slowly turning our shower, sink and toilet a deep orange color over time. Have tried a ton of products to try to fix this issue but nothing works nearly as well as this product. Smells absolutely terrible but works AMAZING. A few spritzes of this and you can watch the orange dissolve away before your eyes. I use this formula for the sink and inside of the shower and use the powder formula inside the toilet as that seems to work better there. As stated earlier, the smell is awful and lingers until you rinse everything down so definitely have windows open when using this product.
This stuff actually works! We opened our office in a space that was once a bakery. The tile floor had several rust stains from old kitchen equipment. I tried everything to get the stains out. I scrubbed with every cleanser anyone suggested. Nothing worked. When I bought and tried THIS product, I was astounded. All the stains are GONE.
This product has been my savior! We live in an area with very a lot of iron in the water. My toilets would end up with golden bowls within 4 days of washing them and even after cleaning seemed to leave a ring. Now I just spray this in and everything looks brand new again.
