As the temperatures rise and flowers begin to bloom, there’s no better time to refresh your backyard oasis. Spring hot tub cleaning is essential for maintaining clean, safe water and keeping your spa in peak condition. At Sunset Spas, we specialize in helping homeowners care for their hot tubs year-round. This guide will walk you through the key steps to give your spa the seasonal tune-up it deserves.
Why Spring Is the Perfect Time to Clean Your Hot Tub
Winter weather can take a toll on your hot tub. Even if you’ve used it regularly, cooler months often mean more debris, water chemistry imbalances, and neglected maintenance tasks. A deep spring cleaning not only prepares your spa for more frequent use but also helps prolong the life of your equipment and cover.
Step 1: Drain the Water
Start by completely draining the water from your spa. Use a built-in drain or submersible pump. This gives you a clean slate to sanitize the tub shell and refill with fresh water. Make sure power to the spa is turned off before draining.
Step 2: Clean the Spa Shell
Use a non-abrasive spa surface cleaner and a soft cloth or sponge to scrub the interior. Pay special attention to waterlines and corners where residue often builds up. Avoid household cleaners that can throw off your spa’s chemical balance.
Step 3: Remove and Clean Filters
Filters trap oils, debris, and other contaminants, so regular cleaning is vital. Remove the filters and rinse them thoroughly with a garden hose. For a deeper clean, soak them overnight in a filter cleaner solution. Rinse again before reinstalling.
Step 4: Inspect Jets and Components
Take a close look at your spa jets and control components. Remove any visible blockages and wipe down controls. Turn the jets on briefly while the spa is still empty to flush out any residual buildup before you refill.
Step 5: Clean and Condition the Hot Tub Cover
Your hot tub cover protects against dirt and energy loss, but it also needs care. Clean the cover with mild soap and water, then apply a UV vinyl conditioner to protect against sun damage and cracking. If the cover feels heavy, it could be waterlogged and might need replacing.
Step 6: Refill with Fresh Water
Once everything is cleaned and inspected, begin refilling the spa with fresh water. Use a hose filter to reduce impurities like calcium or iron. Fill to the recommended water level before turning the power back on.
Step 7: Balance the Water Chemistry
After refilling, test and balance the water. Use a test strip or digital meter to check for pH, alkalinity, calcium hardness, and sanitizer levels. Add necessary chemicals to reach optimal levels:
- pH: 7.2–7.8
- Alkalinity: 80–120 ppm
- Calcium Hardness: 150–250 ppm
- Sanitizer (chlorine or bromine): As recommended
Maintaining proper water balance helps avoid scale buildup, cloudy water, and equipment damage.
Step 8: Shock the Water
Add a chlorine-free shock treatment to oxidize contaminants and boost sanitizer effectiveness. This step ensures your spa water starts the season clean and crystal-clear.
Step 9: Set the Mood
Spring is about renewal—so give your spa environment a refresh too! Add new outdoor seating cushions, update your LED lighting, or incorporate aromatherapy products for a spa-like experience right in your backyard.
