First, turn off the power to your hot tub to prevent electrical hazards.
Locate the drain valve, which is usually near the bottom of the hot tub. Attach a garden hose to the valve and direct the other end to a suitable drainage area. Make sure it’s an area that can handle a significant amount of water and won’t cause damage, like a storm drain or a grassy area away from your home's foundation. Remember, proper drainage is crucial to avoid any water damage.
Open the drain valve and let the water drain completely. This can take several hours, so plan accordingly. Be patient, guys! It's important to let all the water drain out to ensure you’re starting with a clean slate.

2. Clean the Hot Tub Shell

Once the hot tub is empty, use a soft cloth or sponge and a hot tub surface cleaner to wipe down the interior shell. Pay special attention to areas with visible dirt, grime, or water lines. A non-abrasive cleaner is key here; you don't want to scratch the surface of your beautiful hot tub.
For stubborn stains, you might need to let the cleaner sit for a few minutes before wiping it away. Remember, gentle scrubbing is more effective than aggressive scrubbing. Think of it like giving your hot tub a spa treatment!
Rinse the shell thoroughly with a hose to remove any remaining cleaner. It's super important to get all the cleaner off to avoid messing with your water chemistry later. Nobody wants soapy water in their hot tub.

3. Clean the Jets and Nozzles

Jets and nozzles can accumulate mineral deposits and grime over time. To clean them, you can use a jet cleaner or a mixture of vinegar and water. If you're going the vinegar route, mix equal parts white vinegar and water in a spray bottle. It's like a natural cleaning potion for your hot tub!
Spray the cleaner onto the jets and nozzles, and let it sit for about 15-20 minutes. This gives the cleaner time to break down the buildup. You might see some gunk start to loosen up, which is a good sign!
Use a small brush or a soft cloth to scrub the jets and nozzles, removing any remaining debris. An old toothbrush works great for this! Just make sure it’s clean, of course. Remember, little details make a big difference.
Rinse the jets and nozzles thoroughly with water. You want them sparkling clean and ready to blast those bubbles!

4. Clean the Filter

The filter is your hot tub’s first line of defense against dirt and debris, so keeping it clean is super important. Remove the filter from its housing. Remember, the filter location can vary depending on your hot tub model, so check your manual if you're not sure where it is.
Rinse the filter with a hose to remove loose debris. A strong stream of water can dislodge a lot of the big stuff. Think of it as giving your filter a power shower!
Use a filter cleaner to soak the filter. Follow the instructions on the cleaner, as soaking times can vary. This step is crucial for getting rid of the stubborn stuff that rinsing alone can’t handle. Trust me, a clean filter makes a huge difference in water clarity.
After soaking, rinse the filter thoroughly with water until all traces of the cleaner are gone. You don’t want any cleaner residue messing with your water balance. A good rinse ensures your filter is ready to rock and roll!
Allow the filter to dry completely before reinstalling it. A dry filter is less likely to harbor bacteria. It's like letting your hair air dry – sometimes it’s just healthier!

Rinse the cover with water and let it dry completely before placing it back on the hot tub. A dry cover is a happy cover! Plus, it's lighter and easier to handle when it’s dry.

6. Refill the Hot Tub

After cleaning, it’s time to refill your hot tub with fresh water. Insert a hose into the filter compartment to avoid airlocks in the plumbing. This nifty trick helps ensure the water fills smoothly and prevents any air from getting trapped in the system. It’s like giving your hot tub a gentle, even fill.
Fill the hot tub to the recommended water level, which is usually indicated by a line inside the tub. Overfilling can cause issues, so it’s best to stick to the guidelines. Think of it as filling a gas tank – you want it just right!

7. Balance the Water Chemistry

Balancing the water chemistry is crucial for a safe and enjoyable soak. Use test strips or a liquid test kit to check the pH, alkalinity, and sanitizer levels. This is where you become a water chemistry whiz! Remember, balanced water not only feels better but also protects your hot tub’s components.
Adjust the chemicals as needed to achieve the ideal ranges. Typically, you’ll want a pH between 7.2 and 7.8, alkalinity between 80 and 120 ppm, and the appropriate sanitizer level for your chosen product (chlorine or bromine). It's like baking a cake – you need the right ingredients in the right amounts!
Add chemicals gradually, following the instructions on the product labels. It’s better to add a little at a time and retest, rather than adding too much all at once. Think of it as seasoning a dish – you can always add more, but you can’t take it away!
