How do I clean my Hot Tub?

So, you’ve either just invested in yourself and purchased a brand-new Jacuzzi® Hot Tub...or you are busy doing your due diligence prior to making an incredible commitment to your self-care.

Either way, we are here to help you get to grips with hot tub maintenance and how to clean your Jacuzzi® Hot Tub!

Cleaning your hot tub can be split into two main categories if you ask us...the first focuses on keeping your water sanitised and clean and the second focuses on how to clean the hot tub itself. Both are of equal importance and both are really easy to manage alongside our already busy lives. Little myth-buster here for does NOT take a village to keep a hot tub clean and running smoothly (as long as you have had proper training and support from your Jacuzzi® Hot Tub dealer). This is why we always recommend buying from somewhere local and from a reputable dealer that will be there to provide ongoing aftercare for you. 

Let’s dissect things a little further now. To keep your hot tub water clean you will need the aid of Hot Tub Chemicals and filters amongst other things*. We at Hydrolife, as Jacuzzi’s® top retailer believe Bromine to be the best choice of water sanitiser for a few reasons.:

  • It performs incredibly well at high temperatures which is important when you are running water at 35-40c
  • It does exactly the same job as Chlorine but is gentler on skin
  • Only hot tubs manufactured from a certain quality of materials can use Bromine. For as much as it is gentler on skin it is actually harsher on your hot tub. So you know you have bought a quality product if Bromine is the recommended product to use!

*You will also use either pH+ or ph- to help balance the pH of your Jacuzzi® Hot Tub water.


Using Bromine to clean your hot tub water can be done in two ways. You will use Bromine granules first and foremost. These are added straight to the water and provide a fast-acting boost to help keep the water sanitised**. You can also look to use Bromine Tablets in conjunction with the Bromine granules. Bromine tablets provide a constant, slow-release dose into your spa water and act as a great buffer to prevent your chemical levels dropping to zero between testing. Bromine tablets are added on a weekly basis, into a floating dispenser that bobs around in your water all the time – easy as that! We recommend that all of our customers use this dual method to help clean their Hot Tub as it really does make life much simpler!

**We always recommend pre-dissolving your chemicals in a jug of spa water prior to dosing them. 

 Secondary to your water sanitiser of choice, you will use filters to help clean your hot tub. Filters come in all different shapes and sizes and good filtration really is the key to a clean hot tub! Jacuzzi® Hot Tubs all come with at least 3 stages of filtration included...increasing to 5 stages as you go up through the range! We would always recommend going for a model with the greatest number of stages that your budget will allow for, because, more stages = clean, clearer water for longer!


Your pleated hot tub filters are submerged into the water in your Jacuzzi® Hot Tub and then your spa water is pumped through these multiple times per day! As the water passes through these pleated hot tub filters, debris and bacteria are removed from the water – helping to keep your hot tub clean!

We recommend giving your hot tub filters a clean with Filter Cleaner once a week. With instant Filter Cleaner Spray this is just a 5-minute job – phew! Quick note; we recommend that filters are left to dry thoroughly before they are put back into the hot tub. Allowing them to dry will help them perform better for longer. A spare set of filters will be your best friend here!

Now let’s look at how to clean your hot tub itself. This bit, dare we say, is almost just common sense. Aided by a selection of products specially formulated to be used in/on hot tubs.

First and foremost in this category is keeping your hot tub shell surface clean and sparkling! This can be done with a small amount of Surface Cleaner and a microfibre cloth or scum sponge! Either a daily – or a weekly polish over the surface of your shell will keep it clean and shiny! Simple!

If you live in an area with hard water then you will also need to invest in some Anti-Scale to help keep your pipes clean and clear. This is added as a weekly treatment and your local dealer can advise you on the quantity of this that you will need to clean your hot tub.

Quick fact; if you group all of the above testing, dosing and cleaning’d only be looking at approximately 15 minutes per week to clean your Jacuzzi® Hot Tub. Pretty good going wouldn’t you say!

On a longer-term basis, including your quarterly water changes...there is one more product that you will use to clean your hot tub. This is Hot Tub Pipe Cleaner and it does exactly what it says on the tin. Again, your local dealer can advise how best to use this when you are ready to perform a water change. During a water change you also have the opportunity to get in and give all of your hot tub seats and jets a thorough clean with Surface Cleaner – something your future self will thank you for!
