Help Prevent White Stains from Irrigation Water

Hard water can leave behind white stains, spots, and scale buildup on the surfaces around your home. If your irrigation system uses well water with calcium, those deposits can show up on siding, windows, concrete, brick, fencing, patios, and landscape features.

Rid-O-Rust® Calcium & Scale Preventer helps control calcium before it can settle on surfaces or build up inside your irrigation system. Used as directed, it helps protect your home’s curb appeal while supporting better sprinkler system performance.

Protect Your Property Before Scale Builds Up

Once hard water deposits appear, they can be frustrating and time-consuming to remove. Rid-O-Rust® Calcium & Scale Preventer is designed to be used proactively, helping reduce white staining and scale buildup before they become bigger problems.

It can also be used alongside original Rid-O-Rust® stain preventers when your water has both calcium buildup and rust staining concerns.

Frequently Asked Questions

Pro Products

Rid-O-Rust® Calcium & Scale Preventer is a concentrated irrigation treatment used to prevent calcium scale buildup and white staining caused by hard water. It is used when sprinkler systems leave chalky residue on surfaces or clog irrigation components. It helps protect outdoor surfaces and irrigation components from calcium and scale buildup before staining and maintenance problems start.
Rid-O-Rust® Calcium & Scale Preventer works by neutralizing calcium in well water before it leaves visible scale stains on sidewalks, driveways, landscaping features, and other outdoor surfaces. This makes it a preventative treatment rather than a product meant to remove scale after buildup has already formed.
Yes. The product is specifically described for use in irrigation feeder systems. It is intended to help reduce calcium and scale staining while also helping protect sprinkler components from buildup that can contribute to wear and maintenance issues.
Yes. Rid-O-Rust®® Calcium & Scale Preventer is designed to help extend the life of sprinkler components and reduce costly maintenance calls. That makes it relevant for contractors and property owners who want both scale prevention and longer-term irrigation system protection.
Yes. Rid-O-Rust®® Calcium & Scale Preventer is safe for people, pets, and plants when used as directed, which is especially important in residential and commercial irrigation systems where treated water may contact lawns and landscaped areas.
Yes. The product directions say the well water must be tested for iron content, hardness, and pH in order to determine the proper chemical to use. Testing is important because scale problems can be influenced by more than one water condition, and Rid-O-Rust® formulas may not be effective under certain circumstances.
Dosage should be determined for the specific application by using the online dosage calculator. The calculator is designed to help users choose the correct dosage for calcium prevention or rust prevention based on actual water test results.
The dosage calculator guidance says you should have your water test results ready before you begin. Information such as iron content, hardness, and pH is important for selecting the right formula and dosage for the application.
No. Rid-O-Rust® formulas are not effective under every water condition. That is why water testing and proper product selection are important before treatment begins.
