We recently discussed just how easy it can be to maintain your hot tub inside and out. In this post, we’ll continue the conversation about hot tub maintenance, but focusing just on tips for the exterior.

The outside of your hot tub is exposed to the elements year round and can be damaged by UV rays, built-up debris, and falling objects, but you can keep your spa looking good as new with these tactics:

Hot Tub Covers

Purchasing a first-rate hot tub cover is one of the best investments you can make to extend the life of your hot tub and reduce costly hot tub repairs. Covers provide protection not only for the inside of the hot tub, but also the top and edges, keeping them from being exposed to extreme weather conditions and sunlight.

Properly fitting hot tub covers, such as those found in our dealerships, are designed specifically for your hot tub to perfectly fit your hot tub’s every curve. The more snug your cover fits, the better it will be protected from the elements.

Vinyl Covers

If you’re using a vinyl hot tub cover, it’s important to clean it monthly to expand the lifespan of not only the cover, but your hot tub, too.

  1. Begin by hosing down the cover to remove any dirt and debris.
  2. Next, wipe down the outside with a soft cloth or sponge and a high-quality cleaner made specifically for hot tub covers.
  • Alternatively, you can also use a mixture of lukewarm water and mild soap.
  • Never use household products, and avoid scrubbers like steel wool.

Keep in mind that cleaning chemicals can add contaminants to the water and cause problems, and rough materials can scratch or even tear the hot tub cover.

If the underside of the cover needs cleaning:

  1. Spray it with a hose and wipe with a new cloth or sponge.
  2. Be sure to rid the cover of any soap, and then let it air dry.
  3. Once the cover dries, apply your vinyl protector as directed on the packaging.

Fabric Covers

When it comes to fabric covers, one of the best ways to keep them in prime condition is by addressing stains as soon as possible.

  1. Brush away dirt and wipe up spills to prevent them from settling into the cover.
  2. If a stain does make a mark, use a soft nylon brush, dishwasher detergent or a gentle laundry detergent such as ones used for babies and warm water to gently spot clean. Rinse out the detergent and let the area air dry.

Use the same technique to clean the underside of your fabric hot tub cover as you would a vinyl cover.

For stubborn stains, use a fabric stain remover, but consult the hot tub cover packaging for additional instructions. Always rinse off any cleaning products and allow your cover to dry on its own.

Exterior Cabinetry and Shell

The exterior sides of the hot tub, also known as the synthetic cabinet or skirt, are made from sturdy, UV-resistant material that shouldn’t require much cleaning. If it does look like it needs a pick me up:

  1. Spray down the exterior with a hose and nozzle attachment.
  2. Or, wipe it down with a cloth and a mild detergent soap solution.

Similarly, the Jacuzzi® Hot Tub shell is acrylic and nonporous and only needs an occasional swipe of a damp cloth and gentle soap. Do not use abrasive cleaners on the shell, and always ensure all the soap suds are wiped away before refilling the tub.

You could also consider using the Jacuzzi® Spa All-Purpose Cleaner, which is suitable for both the shell and skirt. Simply spray on the solution, wipe down the surfaces with a damp cloth, and rinse. If you need a more aggressive cleaner, contact your Jacuzzi Hot Tubs dealer.


With a little love and attention, your hot tub will not only sparkle on the outside, but will be well-equipped to protect the inside as well. Remember, proper hot tub care is important for both the interior and exterior.
