How to Clean a Jacuzzi


Indulging in a relaxing soak in your jetted tub can be a sanctuary from the stresses of life, but maintaining a clean and sanitary tub is crucial for a truly rejuvenating experience. In this guide, we’ll explore a step-by-step approach using common household items like vinegar and baking soda to ensure your jetted tub remains a haven of relaxation.

Step 1: Initial Flush and Cleaning Solution

Start by clearing any visible debris and filling the tub with hot water, ensuring it covers the jets. You have options for a cleaning solution:

  • Option 1: Pour 2 cups of white vinegar to dissolve buildup without damaging the tub.
  • Option 2: Mix 1/2 cup of bleach with dishwashing detergent (use gloves and goggles with bleach).
  • Option 3: Explore commercial products designed for jetted tub cleaning, following package instructions.

Step 2: Activating Jets and Internal Plumbing

Before turning on the jets, close the air-induction valves (unless the manufacturer suggests otherwise). Run the jets on high for 10-15 minutes, allowing debris from internal plumbing to be expelled into the water.

Step 3: Second Flush

Drain the tub, refill it with warm water, and run the jets on high for another 10-15 minutes to eliminate additional residue. Drain the water.

Step 4: Gentle Tub Scrub with Baking Soda

Sprinkle baking soda generously in the tub, letting it sit for a few minutes. Gently scrub the tub’s interior, faucet, and drain with a soft, damp cloth to remove mold, mildew, and soap scum.

Step 5: Detailed Jet Cleaning

Using a dedicated toothbrush, delicately scrub the jet nozzles and contoured trim. If needed, use dental floss to dislodge buildup. Clean the air-intake cover, rinse thoroughly, and drain.

Step 6: Caulk Scrub

Create a cleaning paste by mixing equal parts baking soda and water. Use the toothbrush to scrub the caulk. For persistent stains, consider a bleach solution (1 part bleach to 10 parts water). Spray, let it sit for 10-15 minutes, and scrub again.

Dealing with Stubborn Stains and Abrasions

For stubborn stains, mix two parts baking soda with one part hydrogen peroxide, apply, and scrub after 30-60 minutes. Hard water stains can be treated with white vinegar-soaked paper towels for two hours, followed by a baking soda paste scrub.

Conclusion: Maintaining Your Oasis

Regular maintenance is crucial for optimal tub performance. Depending on usage frequency, aim for cleaning every month or quarterly. Keep an eye on jet covers for damage, signaling a potential need for replacement. By following these steps, you’ll ensure your jetted tub remains a blissful retreat, free from bacteria, mold, and unwanted debris. Enjoy your next bath without a worry, knowing your sanctuary is clean and inviting.
