How to Clean an Inflatable Hot Tub: Complete Guide
Proper cleaning is essential to keep your inflatable hot tub safe, hygienic, and long-lasting. This guide covers everything from routine maintenance to full deep-cleaning - with step-by-step instructions for Coleman, SaluSpa, and Intex models.
Why Cleaning Your Inflatable Hot Tub Matters
An inflatable hot tub is a warm, moist environment - perfect for bacteria, algae, and biofilm growth if not properly maintained. Regular cleaning prevents:
- Health risks: Bacteria like Legionella and Pseudomonas thrive in poorly maintained hot water.
- Skin irritation: Unbalanced water chemistry can cause rashes, itching, and eye irritation.
- Equipment damage: Scale buildup and biofilm can clog jets, damage the pump, and degrade the liner.
- Cloudy/smelly water: Poor maintenance leads to cloudy, green, or foul-smelling water.
- Shortened lifespan: Neglected tubs degrade faster, reducing your 3-5 year expected lifespan.
How to Deep Clean an Inflatable Hot Tub (Step by Step)
Follow these 8 steps for a thorough deep clean of any inflatable hot tub:
Step 1: Turn Off and Disconnect Power
Turn off the pump, heater, and jets. Unplug the power cord from the GFCI outlet. Safety first - never work with electrical components while connected.
Step 2: Remove and Clean the Filter
Remove the filter cartridge from the pump housing. Rinse thoroughly with a garden hose to remove debris. For deep cleaning, soak in a filter cleaning solution for 12-24 hours. Replace filters that are discolored, damaged, or have been used for 2+ months.
Step 3: Add Line Flush Cleaner (Optional)
Before draining, add a hot tub line flush product to the water and run jets for 20 minutes. This cleans biofilm and buildup from the internal plumbing lines that you can't reach manually.
Step 4: Drain the Water
Connect a garden hose to the drain valve (if equipped) or use a submersible pump. Direct water to a suitable drainage area away from your foundation. Complete draining typically takes 30-60 minutes.
Step 5: Scrub the Interior
Use a soft cloth or non-abrasive sponge with a mixture of white vinegar and water (1:1 ratio) or a dedicated hot tub surface cleaner. Scrub the walls, floor, and jet nozzles. Avoid harsh chemicals, bleach, or abrasive scrubbers that can damage the PVC liner.
Step 6: Clean the Exterior
Wipe down the outside of the tub with a damp cloth. Clean the pump unit housing. Check for any signs of wear, small punctures, or UV damage on the exterior walls.
Step 7: Rinse Thoroughly
Rinse the entire interior with clean water to remove all cleaning solution residue. Pay special attention to jet nozzles and the drain area. Any remaining cleaner can cause foaming when you refill.
Step 8: Refill and Balance Chemistry
Refill with fresh water from your garden hose. Once filled, turn on the pump and heater. Test pH (target 7.2-7.8) and alkalinity (80-120 ppm). Add sanitizer (chlorine or bromine) and let circulate for at least 2 hours before use.
Weekly Maintenance Checklist
Between deep cleans, follow this weekly routine to keep your water clean and clear:
- 2-3x per week: Test pH (7.2-7.8) and sanitizer levels (1-3 ppm chlorine or 2-4 ppm bromine) using test strips.
- Weekly: Add shock treatment to oxidize contaminants and refresh sanitizer effectiveness.
- Weekly: Rinse the filter cartridge with a garden hose to remove accumulated debris.
- Daily: Run the filtration pump for 2-4 hours minimum (more if used heavily).
- After each use: Check sanitizer level and add more if needed. Skim surface for debris.
- Always: Keep the cover on when not in use to retain heat and prevent debris buildup.
Filter Cleaning & Replacement
The filter cartridge is your first line of defense against dirty water. Here's the recommended schedule:
- Every 1-2 weeks: Remove and rinse with a garden hose.
- Every month: Deep-clean by soaking in a filter cleaning solution for 12-24 hours.
- Every 2-4 weeks: Replace with a new filter cartridge (or sooner if visibly damaged or discolored).
Having 2-3 spare filters on hand is recommended so you can rotate while one soaks. Filter cartridges are inexpensive (typically $5-$15 for a multi-pack on Amazon).

How often should I clean my inflatable hot tub?
Perform a full drain-and-clean every 1-3 months depending on usage. With heavy use (3+ times per week), clean monthly. With light use (weekly), every 2-3 months is sufficient. Between deep cleans, maintain water chemistry 2-3 times per week, and clean the filter weekly.
What can I use to clean my inflatable hot tub?
Use a 1:1 mixture of white vinegar and water for general cleaning. For stubborn stains, use a dedicated hot tub surface cleaner (available on Amazon for $10-$15). NEVER use bleach, household cleaners, abrasive scouring pads, or pressure washers - these can damage the PVC material.
How do I clean the jets on my inflatable hot tub?
For air jets, run a line flush product through the system before draining. During cleaning, use a soft brush or old toothbrush to clean around each jet nozzle. You can also soak a cloth in vinegar and wrap it around each jet for 10 minutes to dissolve mineral deposits.
Can I use bleach to clean my inflatable hot tub?
No, do not use household bleach to clean an inflatable hot tub. Bleach can damage the PVC liner, weaken seams, and cause the material to deteriorate. Use white vinegar, baking soda, or a dedicated hot tub surface cleaner instead. Chlorine granules for water treatment are different from household bleach and are safe when used as directed.
How do I prevent mold and mildew in my inflatable hot tub?
To prevent mold: maintain proper sanitizer levels (1-3 ppm chlorine or 2-4 ppm bromine), run filtration daily, keep the cover on when not in use, shock the water weekly, maintain proper pH (7.2-7.8), and do a full drain-and-clean every 1-3 months. If storing, ensure the tub is completely dry before deflating and packing.
How do I get rid of cloudy water in my inflatable hot tub?
Cloudy water is usually caused by unbalanced chemistry, dirty filter, or insufficient filtration. Steps: 1) Test and balance pH and sanitizer levels. 2) Clean or replace the filter cartridge. 3) Run the filtration system for 6-8 hours. 4) Add a water clarifier product. 5) If all else fails, shock the water with a double dose of shock treatment. If still cloudy after 24 hours, drain and refill.
