### ⭐⭐⭐⭐⭐ Gets out stains in just about everything. Just watch your measurements
*by D***S on January 20, 2026*

Good product but if you use to much in your laundry it will eat your fabrics. Lol

### ⭐⭐⭐⭐⭐ Good product
*by E***E on September 2, 2025*

Great for cleaning up grout

### ⭐⭐⭐⭐⭐ Tankless water heater descaler
*by M***O on January 16, 2026*

Descaled my tankless water heater with this. Looking around at MSDS sheets for products specifically marketed for water heater descaling indicates a lot of them are nothing but Sulfamic Acid Crystals, with a recommendation of 1.2lbs in two gallons of water. Just add two gallons of water to a 5gallon bucket, add 1.2lbs of these crystals, now you have a descaling solution.
