6 Top Hot Tub Cleaning Tips – Wave Goodbye to Dirt and Grime

While hot tubs provide a luxurious experience, keeping them clean is the only way to ensure they continue to provide such enjoyment.

When it comes to hot tub care, there is always room for improvement, especially if you’re new to the hot tub ownership world.

If you’re looking for ways to combat sediment buildup on your shell, or simply want to enhance your routine to keep your water fresh and welcoming, keep reading.

In this article, we’re going to share some of the best hot tub cleaning tips to make your routine maintenance even easier, and keep your water crystal clear.

How Often Should I Clean My Hot Tub?

First and foremost, one of the most common questions we answer is, “How often should I be cleaning my hot tub?” and honestly, it depends.

If you use your hot tub frequently or it sees a high number of guests, you may need to clean it more often than someone who reserves theirs for weekend relaxation.

It can also depend on what type of cleaning you’re doing. While you’ll only need to drain and clean your shell every three months, your filters require a more robust cleaning routine.

Below, you’ll find six hot tub cleaning tips and our recommended frequency for each to help guide your cleaning routine.

6 Hot Tub Cleaning Tips For a Clean Spa

Cleaning your hot tub is a multi-step process and will require some trial and error at times to meet your unique needs.

However, the below steps and their corresponding frequency are a great starting point that can work well for nearly all hot tub owners regardless of use!

1. Test and Treat Your Water

Frequency – Three times a week

A clean hot tub all begins with clean, well-balanced water.

If your water isn’t properly treated, it can lead to scale buildup or corrosion eating away at various parts of your system, including your shell!

This makes testing and treating your water crucial to your routine!

When testing your water with your pH strips, you’ll want to be looking for the following levels:

  • pH: 7.2 – 7.8
  • Alkalinity: 80 – 120 ppm
  • Sanitizer
    • Chlorine: 1 – 3 ppm
    • Bromine: 3 – 5 ppm

Not only will keeping these levels balanced ensure your water won’t be damaging to your system, but it also creates a safe, enjoyable soaking experience for you and your loved ones.

2. Clean Your Filters

Frequency – Weekly, Monthly, and Quarterly

Another vital aspect of keeping your hot tub clean is caring for your filters.

Your filters are constantly pulling impurities from your water as it circulates through your system, which can build up over time.

Without regularly cleaning them, this buildup can result in reduced performance, climbing energy bills, and dirty water.

Because they play such an important part in keeping your spa clean, their cleaning routine is more complex than others.

Each week, you’ll want to rinse your hot tub filters under your garden hose to wash away any dirt and debris that’s settled on the surface of the pleats.

Once a month, you’ll want to perform a chemical rinse, spraying them with filter cleaner and allowing them to soak for 15 minutes before rinsing it off.

Finally, every three months, you’ll want to give them a deep clean by soaking them in diluted filter cleaner overnight. This helps lift deeply set stains and build-up to breathe new life into them once again.

3. Use a Spa Vacuum

Frequency – As needed

Even with expert filter care, there are likely going to be times that small debris lingers at the bottom of your spa, such as bits of sand or dirt guests may have brought into the water.

A spa vacuum can easily remove these contaminants from your water, reducing the work your filters will need to do.

Furthermore, if your spa sees heavy use, you may find that a slick layer of sediment forms over your shell between water changes.

A spa vacuum can help keep the underwater surfaces of your shell free from this slippery build-up, making it a useful addition to your monthly routine during times of more frequent use.

4. Clean Your Tub With a Shell Cleaner

Frequency – Every three months

Every three months, you’ll want to do a full water change.

This serves three main purposes:

  • Keeps your total dissolved solids to a minimum
  • Ensures your water remains safe and easy to maintain
  • Allows you to deep clean and inspect your shell

Each time you add a dose of your water treatment products, such as pH increaser or sanitizer, it increases the level of total dissolved solids in your water.

Over time, this accumulation can make your water particularly difficult to balance and can even lead to skin and eye irritations.

By draining your spa, cleaning it, and refilling it with fresh water, you’ll be starting with a clean slate every three months, keeping your water clean, easy to maintain, and safe to enjoy!

Now, you may think cleaning your shell is as easy as rinsing it off with the hose and wiping it with a cloth. This can actually leave behind contaminants that reenter your fresh water.

To ensure you’re truly adding fresh water to a clean tub, you’ll want to clean your shell with a shell cleaner designed for the material your shell is made of.

If you’re not sure which shell cleaner would be best for your spa, talk to the experts at your dealership, and they’ll be able to help you find the right one.

5. Flush The Lines

Frequency – Every three months

During your quarterly drain and deep clean, it’s also a good idea to flush your lines.

This helps remove any biofilm or scale that may have accumulated in your circulation system over the last three months, and helps maintain your spa’s efficiency.

Luckily, this is a simple process!

Simply add some line flush cleaner to your water before draining your spa, and let your pump run it through your system for 20 minutes before you drain your spa.

6. Keep The Exposed Shell Clean

Frequency – Weekly

Lastly, it’s important to wipe down the top portion of your shell that’s exposed.

Each time you lift your cover, this area is exposed to the elements, and because it’s damp, dirt and debris can easily cling to it as you soak.

Wiping this with a soft cloth once a week will help remove any buildup before it gets into your water.

The Best Ways to Prevent Dirt and Grime in Your Hot Tub

If you’re wondering how you can minimize the amount of grime you have to deal with, you’re in luck!

There are various ways you can do this, and they are all incredibly simple to do.

Keep it Covered

The best way to keep your hot tub clean is to simply use your cover!

Anytime you’re not in the water, you should have your cover firmly in place, preferably secured into place with cover locks.

Not only does this keep dirt and grime out of your water, but it also locks in heat to maximize your spa’s energy efficiency.

Use Hot Tub Sponges or Tennis Balls

Each time you settle into the warm water of your spa, oils and dead skin cells are being pulled off your skin and into the water.

This organic matter is difficult for your sanitizer to break down, and can result in cloudy or foamy water if you’re not actively combating it.

One way to do this is by using an oxidizing shock treatment, but if you want to minimize how much shock you need, using hot tub sponges or tennis balls is a great solution!

Simply toss them into the water after you’re done soaking, and they’ll help absorb some of the oils floating on the surface.

Shower Before Your Soak

Speaking of oils, there’s another way to help reduce their accumulation in your water; showering!

Now, we don’t mean taking a full shower each time you want to enjoy a relaxing soak in your hot tub. A quick rinse is all you need.

This helps remove any perfumes, lotions, or sweat that’s on your body, ensuring only minimal amounts will be brought into your hot tub.

Take this a step further by keeping your hair out of the water as you soak so that any hair products don’t melt into the water.

Simply keep hair ties or hats nearby for guests, and you’ll discover a cleaner hot tub with minimal additional effort!

Stick To a Routine

And finally, the best way to keep your hot tub clean is to simply stick to a routine.

This helps ensure every one of your hot tubs needs are met on a regular basis, and provides the care it needs to continue running smoothly for many years to come!
