How often should I use Iron OUT® Rust Stain Remover Powder to keep my bathtub free of rust stains?

+

For routine maintenance, use Iron OUT® whenever you notice new rust stains forming in your bathtub. Its preventive action will help keep your surfaces rust-free and in excellent condition.

What does Iron OUT® Powder do in a water softener?

+

Iron OUT® Rust Stain Remover Powder cleans the mineral bed and removes heavy-duty iron buildup that reduces the softening and recharging efficiency of the water softener resin. The product is backwashed from the system after the cleaning is complete and regular drinking water is resumed. Iron OUT® keeps a water softener cleaned and maintained, working effectively and lasting longer.

When using Iron OUT® Rust Stain Remover Powder in my water softener, will the product get into my drinking water?

+

When used as directed and in a properly working water softener, Iron OUT® will not enter your drinking water. Iron OUT® does not harm your drinking water, the same way the salt in your system does not harm your water supply. Every softener has a mineral bed that water passes through. The mineral bed catches the hardness and iron particles found in the water. When the mineral bed gets compacted with particles, the softener goes into regeneration mode. During regeneration, the water supply goes into bypass mode. The salt brine and Iron OUT® are drawn into the mineral bed of the softener and they remove the hardness and iron particles from the mineral bed. This is flushed down the drain, then 40-60 gallons of fresh water is flushed through the water softener and sent down the drain. Finally, the water softener goes back into service for everyday usage. If you should ever smell or taste chemicals in your water, the lines should be flushed and we recommend contacting a water treatment specialist to service your softener.

If your water softener is not regenerating properly and you can smell or taste Iron OUT® in your water, Iron OUT® can be flushed from the lines by going to the faucet closest to the water softener and allowing the cold water to run. After the odor is gone, turn on other faucets in the home for a short time to make sure the product has been eliminated from all the lines.

Will Iron OUT® Powder remove manganese stains?

+

Iron OUT® may remove manganese stains if used in a higher concentration. Make a paste; apply for 10 minutes and rinse. May be reapplied if necessary.

Is Iron OUT® Powder safe for septic systems?

+

Yes, when used as directed, Iron OUT® Rust Stain Remover Powder is safe for septic systems. This means you can confidently use it to remove rust from bathtubs and other household surfaces without worrying about your septic system.

Are there any surfaces or areas where Iron OUT® Rust Stain Remover Powder should not be used?

+

Iron OUT® Rust Stain Remover Powder is not recommended for use on wood, painted materials, or exposed and corroding metal. Always pre-test in an inconspicuous area and follow the label’s instructions carefully to ensure compatibility.

Iron OUT® Rust Stain Remover Powder is NOT intended for use in swimming pool water, in a greensand filter, on a iron or steam iron, on hair, in a well, on flatware, on cars or to flush closed systems such as car radiators, to clean coffee makers, in a water heater.

Can Iron OUT® Powder be diluted with water and used in a spray bottle?

+

Iron OUT® Rust Stain Remover Powder should only be diluted with water in an open container, such as a plastic bucket, utility sink, washing machine, toilet bowl or bathtub. When Iron OUT® comes in contact with water, a chemical reaction produces an off gas, which if enclosed could cause bursting issues. If a liquid spray is desired for application, we recommend using Iron OUT® Rust Stain Remover Spray.

Why isn't Iron OUT® Rust Stain Remover Powder NSF approved?

+

Iron OUT® is not added to drinking water; instead, this product is a resin bed cleaner. Each softener has a discharge phase. In this phase, per cubic foot, 40-60 gallons of fresh water is flushed through the system and Iron OUT® is completely washed out during this phase. Therefore, it is not NSF approved.
