How to Use Vinegar to Clean Your Hot Tub in 4 Easy Steps

Keeping your hot tub clean doesn’t have to mean using harsh chemicals that can irritate your skin or damage your tub’s components. If you’re searching for a simple, natural way to keep things fresh and running smoothly, vinegar might be just what you need.

Whether you’re dealing with mineral build-up, or lingering odors, or want a more affordable option, this guide will walk you through how to use vinegar effectively. Let’s get started, and soon enough, your hot tub will be clean, safe, and ready for a relaxing soak.

The Benefits of Using Vinegar to Clean

Vinegar is a surprisingly powerful ally. It’s natural, safe for your skin, and won’t damage the components of your tub. Here’s how it addresses the specific issues you might be facing:

  1. Natural Cleaning Solution: If you’re concerned about harsh chemicals, vinegar is a great alternative. It’s non-toxic, biodegradable, and safe for the environment, making it perfect for those who want to avoid synthetic cleaners.
  2. Preventing Damage to Hot Tub Components: Vinegar is gentle enough not to harm your hot tub’s acrylic shell, jets, or filters. It’s acidic but not overly so, meaning it can clean effectively without causing wear and tear on your tub’s materials.
  3. Dealing with Mineral Build-Up: Hard water can leave behind calcium and lime deposits, which can be tough to remove. Vinegar, thanks to its acidity, breaks down these deposits, making it easier to scrub them away and keep your tub looking pristine.
  4. Eliminating Odors: If hot tub develops an unpleasant smell, vinegar can help neutralize those odors. Its natural deodorizing properties can tackle and remove the source of the smell, leaving smelling fresh.
  5. Mold and Mildew Removal: Vinegar is also effective against mold and mildew. These can be common issues in hot tubs due to the moist environment, but vinegar’s antifungal properties can help clean and prevent these growths from taking hold.
  6. Maintaining pH Balance: Vinegar can slightly lower the pH of your hot tub water. While you’ll need to monitor your water’s chemistry after using it, vinegar won’t drastically alter the pH, making it a safer option for regular cleaning.
  7. Cost-Effectiveness: Vinegar is inexpensive and easy to find, making it a budget-friendly option for regular hot tub maintenance. You won’t need to spend a lot on fancy cleaners when a bottle of vinegar can do the job.
  8. Ease of Use: Cleaning with vinegar is straightforward. You can dilute it with water, spray it on the surfaces, let it sit for a while, and then wipe it off. For deeper cleaning, you can fill your tub with a vinegar solution and run the jets, allowing it to clean the internal components as well.

Why Use Vinegar to Clean Your Hot Tub

Vinegar is an all-natural cleaning agent that is safe and effective in removing dirt, grime, and bacteria from surfaces. It is also environmentally close and does not include harsh chemicals or toxic substances that could harm you or the environment. 

What Type of Vinegar to Use: Using the correct type of vinegar is essential. Distilled white vinegar is the most effective for cleaning and is readily available in most grocery stores.

Avoid using apple cider vinegar or other flavored kinds of vinegar as they may leave behind a residue that could be difficult to remove.

Lucy’s Distilled White Vinegar is a natural and versatile product used for cooking, cleaning, and more. It is preservative-free, has a rich and robust flavor, and can help you reduce salt intake.

Preparation: It is essential to prepare the surface by removing any loose dirt or debris before cleaning your hot tub with vinegar. Use a skimmer or a vacuum to remove any floating debris, and then use a brush to scrub the borders and floor of the hot tub. This will help to loosen any stubborn grime or bacteria that may be present.

How to Use Vinegar to Clean Your Hot Tub

Step 1: Drain and Rinse

First, drain it completely and rinse it with clean water. This will help remove any loose dirt, debris, or residue in the water or on the surface. You can rinse thoroughly using a hose or a bucket.

Step 2: Make a Vinegar Solution

The next step is to make a vinegar solution to scrub. The best type of vinegar is distilled white vinegar, which has an acidic level below 4 pH.

You can find it in most grocery stores or online. Mix one part water and vinegar in a large bucket or spray bottle to make the solution. You will need enough solution to cover the entire surface.

Step 3: Use the Scrub

The third step is to use scrub with the vinegar solution. You can use a sponge, a brush, or a cloth to apply the solution and scrub on the surface. Pay special attention to the sides, bottom, and fixtures of your hot tub, where dirt and bacteria may accumulate.

You can also use a toothbrush to clean hard-to-reach areas or crevices. Let the solution sit for 10 minutes before rinsing it with clean water.

Step 4: Refill and Balance Water Chemistry

The final step is to refill it with fresh water and balance its pH and sanitizer levels. Vinegar can lower the pH of your water, so you may need to add some pH increaser or baking soda to bring it back to the ideal range of 7.2 to 7.8.

You should also check the sanitizer level of your water and add chlorine or bromine tablets if needed. To measure your water’s pH and sanitizer levels, you can use a test kit or strips.

And that’s it! You have successfully cleaned your hot tub with vinegar. Enjoy your sparkling and sanitary spa!

How to Use Vinegar as a Descaler

If it starts to look dingy, it may be time to describe it. It is a great natural option for descaling hot tubs with vinegar. It is much cheaper than store-bought options. Plus, you already have it in your kitchen! Here’s how to use it:

  1. Fill it with water and add 1 cup of vinegar for every 100 gallons.
  2.  Turn on the jets and let the mixture circulate for about an hour.
  3.  Drain the water and rinse it well with fresh water.
  4.  Repeat steps 1-3 if necessary.

Are There Alternatives to Vinegar?

Baking Soda: Baking soda is a mild, all-natural abrasive that is safe and effective for cleaning. It can be used alone or in combination with vinegar to remove dirt, grime, and stains.

Hydrogen Peroxide: Hydrogen peroxide is another all-natural, safe, and effective option. It can be used alone or in combination with vinegar to remove dirt, grime, and stains.

Lemon Juice: Lemon juice is a natural acid that can be used to clean a hot tub. It is particularly effective in removing mineral deposits and restoring the shine to the surface.

Commercial Hot Tub Cleaners: Hot tub cleaners are specifically designed for cleaning hot tubs and come in various formulas to address different cleaning needs. They are often more effective in removing stubborn stains and restoring shine to your hot tub’s surface, but they may contain harsh chemicals or toxic substances.

Muriatic Acid: Another Option for Cleaning

Vinegar is not the only acid that can help. Muriatic acid, also known as hydrochloric acid, is another option that can remove stains, dissolve scale, and control algae and mold. 

However, muriatic acid is much stronger and more dangerous than vinegar, so you need to be extra careful when using it.  Muriatic acid can irritate your skin and eyes, damage your equipment, and lower the pH of your water too much. 

You should always wear protective gear, dilute the acid with water, and test the water before and after using it.  You should also neutralize any leftover acid with baking soda and rinse it well. It can be effective but should be used sparingly and cautiously.

Step-by-Step Guide to Cleaning Hot Tub Jets with Vinegar

This approach ensures the hot tub stays clean and functioning well without the need for harsh chemicals. Regular cleaning with vinegar can help prevent clogs and maintain overall efficiency.

  1. Turn Off the Power: Before starting, make sure to turn off the power to the hot tub. This is important for safety and to prevent any damage.
  2. Drain the Water: If the water is dirty or has been sitting for a while, it’s best to drain it completely. If the water is still relatively clean, it can stay in for the cleaning process.
  3. Prepare the Vinegar Solution: Mix white vinegar with water in a 1:1 ratio. For a deeper clean, you can use undiluted vinegar. If the jets have a lot of build-up, undiluted vinegar is more effective.
  4. Refill the Tub (If Drained): If the water was drained, refill just enough to cover the jets.
  5. Add Vinegar to the Water: Pour about 2-4 cups of vinegar into the water, depending on the size of the hot tub. The vinegar will circulate through the jets and help break down any build-up.
  6. Run the Jets: Turn them on and let them run for 15-20 minutes. The vinegar will circulate through, loosening any debris, mineral deposits, or grime inside.
  7. Turn Off the Jets and Let It Sit: After running the jets, turn them off and let the vinegar solution sit for an additional 15-30 minutes. This gives the vinegar more time to work on any stubborn build-up.
  8. Drain the Water: Once the soaking period is complete, drain the water. This will also flush out any remaining debris from the jets.
  9. Rinse the Jets: Refill the hot tub with clean water and run the jets for a few minutes to rinse out any remaining vinegar residue. Drain the water again if necessary.
  10. Final Refill: Once satisfied that the jets are clean and free of vinegar, refill the hot tub with fresh water. Check the pH levels to ensure they’re balanced before turning the power back on and enjoying a relaxing soak.
