Step-by-Step Guide to Getting Rid of Hot Tub Odors

Test and Balance the Water

• Use test strips or a water test kit to check pH, alkalinity, and sanitizer levels.

• Adjust the pH to stay between 7.4 and 7.6.

• Make sure sanitizer (chlorine or bromine) is at proper levels to kill bacteria.

Clean or Replace the Filter

• Turn off the power and remove the filter.

• Rinse the filter thoroughly with a hose.

• Soak it in a filter cleaner if needed, then rinse and let it dry.

• If the filter is worn out, replace it with a new one.

Shock the Water

• Add a shock treatment to eliminate organic contaminants and bacteria.

• Follow the manufacturer’s instructions for dosage.

• Keep the cover off and let the water circulate for a few hours.

Clean Hot Tub Surfaces

• Wipe down the hot tub shell with a surface cleaner and soft cloth.

• Pay attention to corners, jets, and under the cover where residue builds up.

• Rinse thoroughly to remove any cleaner residue.

Drain and Refill if Necessary

• If odors persist, it may be time for a full water change.

• Drain the tub completely and scrub the interior.

• Refill with fresh water and balance chemicals properly.

Advanced Tips for Odor Prevention

• Shower before using the hot tub to reduce contaminants.

• Run the circulation system daily to keep water moving.

• Use an enzyme product regularly to break down oils and organic material.

• Keep the cover clean and dry to prevent mildew.

• Schedule regular maintenance checks to catch problems early.

Avoiding Common Mistakes

• Letting water chemistry get out of balance for too long.

When to Call a Professional
