How to Decontaminate Your Hot Tub

A contaminated hot tub can be a frustrating and concerning issue. Whether you’re dealing with cloudy water, foul odors, or lingering bacteria, taking the right steps can restore your spa to its clean and inviting state. Follow this guide to learn how to decontaminate your hot tub effectively and enjoy a safe soaking experience once again.

1. Recognize the Signs of Contamination

Knowing when your hot tub needs decontamination is key. Here are common signs:

• Cloudy or Discolored Water: This can indicate bacteria or organic buildup.
• Foul Odors: Bad smells often point to biofilm or other contaminants.
• Foam or Residue: Excessive foam or slimy surfaces can signal water chemistry issues.

If you notice any of these signs, it’s time to act quickly to avoid further complications.

2. Drain the Hot Tub Completely

To eliminate contaminants, start by draining the water. Follow your hot tub manufacturer’s instructions to safely remove all water from the spa. This allows for a thorough cleaning of both the shell and internal components.

3. Use a Plumbing Line Cleaner

Biofilm and bacteria can accumulate inside the plumbing of your spa. Use a line flush product designed for hot tubs to clean these areas:

• Apply the Cleaner: Add the recommended amount of line flush to your spa before draining.
• Run the Jets: Turn on the jets to circulate the cleaner through the plumbing system.
• Rinse Thoroughly: After draining, rinse the interior to remove any remaining residue.

4. Clean and Inspect the Filters

Filters play a critical role in maintaining clean water. Remove the filters and clean them thoroughly with a filter cleaner solution. If the filters show signs of wear, replace them to ensure proper filtration going forward.

5. Scrub the Shell

Use a non-abrasive cleaner to scrub the interior surfaces of your hot tub. Pay attention to corners, jets, and other hard-to-reach areas where contaminants might hide. Avoid household cleaners, as they can leave residues that disrupt water chemistry.

6. Refill and Balance the Water

Once your hot tub is clean, refill it with fresh water. Use test strips to ensure the water is properly balanced:

• Sanitize: Add chlorine or bromine to kill any remaining bacteria.
• Adjust pH and Alkalinity: Use a pH increaser or decreaser to maintain levels between 7.2 and 7.8.
• Shock the Water: Perform a shock treatment to eliminate organic contaminants.

Prevent future contamination by adopting a consistent maintenance routine:

• Test Water Weekly: Regular testing helps catch imbalances early.
• Clean Filters Monthly: Keep filters in top condition to ensure efficient filtration.
• Drain and Refill Quarterly: Refresh your water every three months to maintain optimal cleanliness.
