How to Clean Jetted Tubs With Dishwasher Tablets

Hot tubs can get very dirty for a variety of reasons, such as hard water deposits or dirt. However, the dirt caused by the water entering the jets is much more problematic.

To make sure you have the best experience in your hot tub, we’ve created this guide on how to clean your hot tub with regular dishwasher detergents and other common household products.

We also have a lot of tips and tricks on how to use dishwasher tablets to clean your hot tub. You don’t have to worry anymore about dirty bacteria or black mold ruining your bathing experience.

Why Should a Hot Tub be Cleaned?

Bathtubs can collect a lot of dirt, mold, and other bacteria if they are not cleaned regularly. Body oils, soap, bath bubbles, and other products contribute to making your bathtub dirtier every time you use it.

Not only do these bacteria dirty up your bathtub and bath water, but all these bacteria can also get into your body and make you sick, or cause other health problems.

Taking a bath in a tub that hasn’t been cleaned properly for a long time is not healthy. A clean bathtub and bath water are essential for you to get the therapeutic properties of a bubble bath.

How Often Should You Clean a Jetted Tub?

You should clean the jets on your hot tub at least once a month, depending on how often you use the tub. It would be best if you could clean the tub properly after about every five uses. And as with the rest of the bathroom, we recommend washing the inside and outside of the bath once a week to prevent bacteria and dirt from accumulating.

Step-by-Step Guide How to Clean a Jetted Bathtub With Dishwasher Tablets

Cleaning a hot tub is not difficult, but it can be a bit time-consuming. You can clean most hot tubs with ordinary household products that you have at home. Below is a step-by-step guide on how to clean your hot tub with ordinary dishwasher tablets.

What You Will Need

Here’s a list of all the ingredients you will need for this guide. Most of these products you probably already have in your home, if not, you can easily get them at your local convenient store.

  • Any type of measuring cup
  • A brush, either toothbrush or a bottle brush
  • Any type of sponge
  • Any dishwashing tablet
  • Some clean microfiber cloths
  • A bowl
  • A clean bucket
  • White vinegar (distilled) OR Chlorine Bleach
  • Some ordinary baking soda

1. Wipe The Tub Down With a Damp Cloth

First, use a damp microfiber cloth or sponge to remove any of the visible dirt in your bathtub. Make sure you clean it properly as the dirt may be stubborn.

2. Fill the Tub up With Hot Water

Next, pour hot water into the bathtub until all the jets are completely underwater. Add a dishwasher tablet to the hot water until it is completely dissolved. You can also add half a cup of white vinegar OR chlorine bleach to the water.

Close the air-induction valves to the jets, unless the manufacturer says to leave them open. This will help make sure your jets get a deep clean, as the water only travels through the tub’s inner tubes.

3. Run the Jets for 15 Minutes

Run the jets for about 15 minutes on high pressure, this will flush out all the dirt from the inner tubes.

Turn off the jets and drain the tub completely. Go over the tub and scrub it well with a brush to remove any leftover dirt.

4. Clean With Baking Soda

Get a bowl of hot water and dissolve about one cup of baking soda. Dip the brush in this solution and scrub the insides and outsides of the jets, making sure to get all the remaining dirt.

Sprinkle some dry baking soda in the tub and use a damp cloth to wipe down the entire inside of the tub.

5. Rinse and Wipe Clean With Microfiber Cloth

Rinse the tub with hot water and wipe everything down with a clean microfiber cloth. Now your tub should be as clean as new.

Clean Your Jetted Tub Regularly

The above process may not be difficult, but it is very time-consuming. You probably don’t want to go through this process every time you have to clean your tub. By cleaning your tub on a regular basis, you won’t have to do an as in-depth clean every time.

Avoid using bath oils in your bath as these leave behind residue in the jets which can lead to black mold. Also try to avoid using any abrasive cleaning agents in the tub as this will wear down the finish and cause stains that very easily collect dirt.

If the finish in your tub is worn down, you can use any car wax that is made specifically for plastic.
