What Are the Black Flakes Coming Out of My Jacuzzi® Bathtub Jets?

If you’re the owner of a luxurious Jacuzzi® bathtub, you’ll already be familiar with the many benefits these innovative jetted bathtubs provide. However, even the best bathtubs on the market need a bit of TLC once in a while to keep them sparkling clean and ready to relax in at any time. While Jacuzzi® products are known for being remarkably easy to maintain, one not-so-relaxing sight you may see anyway are black flakes that come out of the jets in your tub. If you’re wondering what exactly those flakes are—and how you can keep your Jacuzzi® bathtub clear of them—you’ve come to the right place.

Understanding Bathtub Buildup

Those black flakes that you may have seen coming out of your Jacuzzi® bathtub jets are likely made of some combination of mold and mildew, bacteria from bathing, soap and oil residue, or other materials that have been left behind in the piping of the tub when it was last used. Essentially, while the tub itself is not susceptible to bacterial growth, buildup can find its way into the pipes, where it can grow with the water that has been left behind.

These black flakes are nothing to be too worried about, though, and can easily be prevented or cleaned out without you having to put in too much effort in the process.

How to Clean Out Your Jacuzzi® Bathtub Jets

Now to the nitty-gritty part: cleaning out those black flakes from your Jacuzzi® bathtub jets. There are some cleaning solutions that are designed specifically for jetted bathtubs, but if you want to try a DIY approach you can:

  • Fill your tub with hot water and make sure it is filled to at least a couple inches above the highest jet
  • Add distilled white vinegar (a half-gallon is usually the recommended amount)
  • Run the jets for about 15 minutes
  • Drain the tub before refilling it with cold water
  • Run the jets again for about 10 minutes
  • Drain the tub one more time before gently wiping it clean with a cloth

How to Prevent Buildup In Your Jacuzzi® Bathtub Jets

When it comes to keeping black flakes out of your Jacuzzi® bathtub jets, prevention is the best medicine. Regular cleaning—preferably before and after each use, but at the least every month—is the best way to do that, as is making sure you run the jets regularly to keep anything from collecting in the pipes. When in doubt, though, call in the experts at Jacuzzi Bath Remodel for some expert advice.

We know Jacuzzi® bathtubs inside and out, so whether you need some tips on maintaining your current tub or want to add a brand-new one to your home, we’re the company to call for it all. So, now that you know what those black flakes coming out of you Jacuzzi® bathtub are, how to clean them out, and how to keep them from returning, you can get back to enjoying your tub and all its hydrotherapeutic benefits without worrying.

Jacuzzi® Bathtubs & Jacuzzi® Bathtub Jets: Frequently Asked Questions

If you’ve come to the web looking for an answer to your question about your Jacuzzi® bathtub or its jets, we’re likely to have your answer. Here are some of the most frequently asked questions we get from our customers:

How Can I Maintain a Clean Jacuzzi® Bathtub On a Regular Basis?

What’s so incredible about Jacuzzi® bathtubs in general is that they’re exceptionally easy to clean and maintain, so the answer to this question is luckily pretty basic! Because they’re crafted with nonporous acrylic, these bathtubs aren’t going to require hours upon hours of scrubbing and bleaching.

But to make sure you’re keeping it as clean as possible, giving it a quick rinse after each use to prevent permanent stains. You should also remove hair and other debris from the drain, refrain from using products that stain, secure heavy items so that they don’t fall and crack the acrylic, and cleaning with non-abrasive materials and chemicals that aren’t overly harsh.

Can I Use Bleach to Clean My Jacuzzi® Bathtub?

We recommend that you don’t use bleach or other abrasive chemicals when you’re cleaning your bathtub, as these cleaners can corrode, discolor, and damage the material. You may not see immediate effects, but these chemicals can break down acrylic over time and damage the beauty of your stunning Jacuzzi® bathtub.

Can I Clean the Bathtub’s Filter, & How Often Should I Do It?

You absolutely can clean your bathtub’s filter as regularly as you want to prolong its lifespan. Your filter traps debris, oils, and other particles and prevents them from reentering the water. Of course, the more overloaded the filter gets, the less effective it will be. And while regular cleaning is wise, you’ll also want to stay on top of your filter replacements, which should happen every 3 to 6 months.

How Can I Prevent Mold & Mildew Growth in My Jacuzzi® Bathtub?

Here’s the good news: You shouldn’t have to do anything to prevent mold or mildew from growing on the surface of your Jacuzzi® bathtub. Why? Because the nonporous acrylic it’s crafted from will do that for you! This material is known for being resistant to mold and mildew growth, which is why it’s so low maintenance and easy to clean.
