How to Clean Your Hot Tub-A Step by Step Guide to Doing it Right

Olympic Hot Tub Head Service Tech Reg Akright at Hot Spring Spas factory April 2013REG’S STEP-BY-STEP GUIDE TO CLEANING YOUR HOT TUB.

It’s easy to put your hot tub in top condition…thanks to these tips from Reg Akright, Head Service Technician, who’s celebrating 23 years at Olympic Hot Tub. That’s Reg at right in front of the Hot Spring factory in Vista, California.


If you haven’t used your hot tub in awhile, but the water’s been sitting in it, use System Flush to clean out any mold, organic matter or bio-film from the plumbing lines.

To properly system flush your tub, remove the filters turn on the jets and pour System Flush directly into the filter compartment.  Run all jet pumps for at least 45 minutes, open up the waterfall-if you have one on your tub-and turn all valves & levers. Then, turn the jets off and let your tub sit overnight with the power on and circulating pump running. Drain the next day following the instructions on the bottle. Most “icky” stuff hides where you can’t see it. Use System Flush to “detoxify” and remove build-up from normal use.  Restores plumbing and jets to like-new condition.

Let sit overnight and then drain.

Now’s a perfect time to try SilkBalance! It’s all-natural & gives you soft smooth skin after every soak. No testing or mixing or adding anything but SilkBalance and shock. Before you do, add System Flush to your tub and let sit overnight. Most “icky stuff” hides where you can’t see it. Use to “detoxify” and remove build up from normal use.


Unplug 110V spas; turn all breakers off on 220V spas.

Use only shell cleaning agents approved by the manufacturer:  Windex®, SoftScrub®,Alkalinity Increaser (baking soda). For best results, use GelGloss Cleaner® and a Merlin Magic Sponge. GelGloss is thick and effective for removing oils, dirt, and scum from all spa surfaces, plus it won’t scratch. Protects and polishes the spa surface, repels dirt.


Do you see mounds of fine, yellowish powder inside the equipment bay or near the spa, and reddish brown ants about ½” long? If you answered, yes, take action immediately.  Call an exterminator to rid your spa of carpenter ants. Other critters might have nested over the winter. If you see signs of them, call our Service Center 206-431-2876 for the rodent ridding fact sheet before acting!


Clean filters per the directions in your Hot Spring  Owners’ Manual using SeaKlear Spray Filter

Hot tub maintenance service by Olympic Hot Tub and let us do all the work.

Cleaner or SeaKlear Filter Soak.  Spray spa filter, let soak and rinse off. Removes grease, oils and debris that collect on spa filters. Rejuvenates them to top filtering power. The WaterWand™ hand held filter cartridge cleaner is a big help when cleaning, too. Attach to hose; flick the switch. Saves water use by 50%.

Over time the ability of filters to remove oils and fine particles from the water diminishes. Change filters every two-three years for superior water quality and lower chemical use.  Change filters every 2-3 years for superior water quality and lower chemical use.  If filters are clogged, dirty, cracked or pulled away from the base or darker than a manila folder, replace immediately.

If your spa is over 3 years old and you’ve never had new filters, order some today.


When refilling, allow hose to run a few minutes (low pressure is fine), onto lawn or flowerbeds, before putting it into your spa. Avoid nuisance service calls·always feed hose into your filter compartment when filling. This help prevents air locks that stop your tub from heating!

  1. Thanks for the reminder, Karen.
    We recommend 303 Aerospace Protectant for all hot tub covers.
    303 is the leader in UV screening technology by acting like an “SPF 40” sunscreen for your hot tub cover.
    Regular use provides 100% protection against UV damage that causes slow fade and vinyl breakdown.
    It’s long lasting and biodegradable. It repels dust, soiling and staining.
    The best thing is that treated surfaces stay clean longer. Regular use extends cover life.
    TIP: For best results spend 10 minutes once a month cleaning and conditioning your cover.
    Available at our estore: https://www.olympichottubestore.com/303aepr.html
    Note: We do NOT recommend using Armor All on a hot tub cover–it will prematurely seal the vinyl and cause your cover to age more quickly!
    Best wishes,

  2. · Perform a complete hot tub inspection if you’ve just bought a new home with a hot tub or haven’t used yours in awhile.

  3. Hi Panama:
    Good point. It’s especially important to have an inspection done on an existing hot tub before you buy a new home with a hot tub. We offer that service-a complete tune-up or a valet service to show new owners how to operate and use their new tub. Check out all of our services for tub owners here: https://www.olympichottubestore.com/services.html.
    Thanks for your comment.

  4. It is important that you are using the right chemicals for your hot tub. Sadly the pool industry has many chemicals that use out dated technology and lack the necessary ingredients to properly clean a hot tub. When buying pool chemicals it is important to remember that not all pool chemicals are the same, simply put some work and others do not.
    Biofilm is a serious problem in many hot tubs because there is stagnant warm water sitting in the plumbing lines which creates a perfect place for bacteria and other microorganisms to breed. After an extended amount of time this bacterial build up forms what is called biofilm.
    Because of biofilms biological properties it is not effected by traditional cleaning products such as chlorine, bromine, uv, and ozone just to name a few. In order to actually clean a jetted tub you must use a cleaning product that is specifically designed for the removal of biofilm from the entire hot tub system.

  5. Hi Avi:
    Couldn’t agree with you more about biofilms & the need to get rid of them in hot tubs.
    That’s why we use SilkBalance. When starting someone with an existing hot tub out on SilkBalance, we recommend a complete system flush using Clean Start

    Thanks for writing,
