Protect your spa or hot tub with SpaGuard's Stain and Scale Control. This essential product helps spa owners prevent and eliminate stains caused by iron, copper, and manganese, as well as scaling resulting from high calcium levels. Its effective formula bonds to troublesome metal ions in your spa water, while also eliminating scale buildup that can lead to cloudy water. With just a simple weekly application of this powerful liquid formula, you can ensure that your spa remains free from these common threats.

Say goodbye to unsightly stains and stubborn scale buildup in your spa or hot tub. SpaGuard's Stain and Scale Control provides the solution you need for a crystal-clear and inviting spa experience. Trust in this reliable product to protect your spa from the damaging effects of metals and calcium buildup, keeping your water pristine and your spa ready for relaxation.


  1. Pour the entire dosage directly into the spa water with the pump operating. Keep the pump operating for at least 2 hours.
  2. Some existing stains may be removed by brushing the stain with a spa brush after the application of Stain & Scale Control (we recommend a scum bug.)
  3. Weekly application of 1 oz. per 300 gallons is recommended to prevent scale and stains.
  4. Clean the filter according to the label directions for your type of filter using SpaGuard Filter Cleaner & Degreaser. This will allow Stain & Scale Control to work properly.


1 fl oz per 300 gallons of water per week
