How to Properly Maintain a Whirlpool Tub. Having a whirlpool tub in your home means you can have a spa-like experience any day of the week. However, unlike going to the spa, you have to clean up afterwards and maintain your equipment. While there are certain necessary procedures to maintaining your whirlpool tub, they're nothing that will be too difficult to complete. Proper use and maintenance will ensure your tub can be enjoyed for many years.
Determine your usage. If you use your tub regularly, then more regular monthly cleaning and maintenance is going to be necessary. If you only use your tub occasionally, maintenance every three to four months will be adequate.
Set air control knobs. If your tub has this feature, make sure they are closed.
Fill tub. Fill the tube high enough so that it reaches nearly two inches above the highest jets. This water doesn't have to be hot, but it will be more effective if it's at least warm.
Add a cleaning solution. Add two tablespoons of dishwasher detergent to the tub of water. This can be regular detergent that you would use in your dishwasher. Powder or liquid will work.
Run the whirlpool. Turn the tub's jets on and let it run for 15 to 20 minutes. This lets all the soapy water run through the tub's plumbing system to clean out any residue in the pipes.
Drain and rinse. Allow the tub to drain normally, rinse the tub out and then clean the tub itself with a non-abrasive cleanser.
Use bleach in the next cleaning. Add 1/2 cup of regular, household bleach to the water when you clean the tub next time.
Avoid high sudsing soaps. When bathing in your whirlpool tub, do not use bath salts, mineral salts or bubble bath. The use of very high sudsing soaps is also not recommended. These salts and soaps can cause residue to build up in the plumbing system of the tub. When fresh, clean water runs through the lines that have this residue, it runs back into your bathtub, contaminating your clean water.
