A hot tub is a sanctuary of relaxation, comfort, and hydrotherapy—but only if it’s clean and well-maintained. A neglected spa can quickly become a haven for bacteria, algae, and scum, turning your peaceful soak into a health hazard. Fortunately, with the right process and tools, you can clean your hot tub like a pro and keep it sparkling clean all year round.
Whether you’re maintaining a personal spa or looking for insight on professional techniques, this guide provides a step-by-step process to deep clean a hot tub, build a sustainable hot tub cleaning schedule, and even use eco-friendly alternatives like a natural hot tub cleaner. If you're based in Michigan, we'll also cover some pro tips from industry experts offering Hot Tub Cleaning in Detroit.
Step 1: Create a Hot Tub Cleaning Schedule
Before diving into the scrub work, it's crucial to establish a Hot Tub Cleaning Detroit Regular cleaning minimizes build-up, maintains water balance, and extends the life of your spa components. Here’s a simple cleaning routine:
Every 1-2 days: Check water pH, chlorine/bromine levels.
Weekly: Clean filters, skim surface, wipe around waterline.
Monthly: Deep rinse filters, inspect jets and pump.
Every 3-4 months: Fully deep clean the hot tub (drain, scrub, and refill).
Annually: Inspect and clean internal components and cover.
Consistency is key. Setting reminders or marking your calendar helps ensure that your hot tub never gets out of hand.
Step 2: Turn Off Power and Drain the Hot Tub
Always begin by shutting off the power at the circuit breaker to avoid electrical hazards.
Next, drain the hot tub completely. Most spas have a drain spout or plug—follow your manufacturer’s instructions to ensure proper drainage. If your tub is installed indoors or without easy access to an outdoor drain, you may need a submersible pump to speed up the process.
Pro Tip: Use a natural hot tub cleaner before draining, like an enzyme-based cleaner or white vinegar to pre-treat surfaces and loosen biofilm buildup. These are non-toxic and won’t harm your spa’s components.
Step 3: Deep Clean Hot Tub Surfaces
Once drained, it’s time to deep clean the hot tub interior. Use a non-abrasive sponge or microfiber cloth along with your preferred cleaner. You have two options:
Commercial Spa Cleaners: Look for non-foaming, spa-safe products designed to break down grease and scale.
Natural Hot Tub Cleaners: A mixture of white vinegar and water or baking soda paste can be just as effective for removing grime and stains—especially if you prefer a chemical-free approach.
Make sure to clean the following areas thoroughly:
Shell interior
Jet nozzles and controls
Waterline (common area for buildup)
Headrests and cup holders
Avoid household cleaners containing bleach, ammonia, or oils, as these can damage the spa shell and disrupt water chemistry.
Step 4: Clean or Replace Filters
Dirty filters are one of the main causes of cloudy or unsanitary water. During your deep clean:
Remove filters and rinse with a garden hose to dislodge debris.
Soak them overnight in a filter cleaning solution or a 50/50 vinegar-water mix.
Rinse again and allow to dry completely before reinserting.
If the filter is more than a year old or shows signs of wear, consider replacing it. Clean filters not only improve water clarity but also increase the efficiency of your hot tub's circulation system.
Step 5: Hot Tub Algae Removal
If you notice green water, slippery surfaces, or discoloration, you likely have algae buildup. Hot tub algae removal requires swift action:
After draining, scrub affected areas with an anti-algae cleaner or diluted bleach solution (1 part bleach to 10 parts water).
Be thorough—clean jets, corners, filters, and covers where algae spores may linger.
Rinse multiple times to ensure all chemical residues are gone before refilling.
To prevent future growth, maintain water chemistry and shock your spa regularly.
Step 6: Refill and Balance the Water
Once your tub is spotless:
Close the drain plug.
Refill the tub with a hose filter (to avoid introducing metals or contaminants).
Turn power back on and heat the water.
Add water treatment chemicals: pH balancer, sanitizer (chlorine or bromine), alkalinity adjuster, and calcium hardness as needed.
Test water 24 hours later and adjust accordingly. Keep a testing kit or test strips on hand to monitor levels regularly.
Step 7: Clean the Hot Tub Cover
Don’t forget the cover! It collects condensation and debris, which can contribute to bacteria growth. Clean it with mild soap or a natural hot tub cleaner, rinse well, and allow it to dry completely before placing it back.
If mold or mildew is present, wipe it down with a solution of white vinegar and water. Applying a vinyl protectant afterward can prolong its life.
Eco-Friendly Cleaning: Using a Natural Hot Tub Cleaner
For those seeking green cleaning solutions, natural hot tub cleaners are safe, effective, and environmentally friendly. These can include:
White vinegar: Great for descaling and removing grime.
Baking soda: Effective on tough stains without scratching surfaces.
Enzyme-based cleaners: Break down organic materials and biofilm.
Citrus-based degreasers: Good for lifting oils from the waterline.
Natural products reduce chemical exposure and are ideal for people with sensitive skin or allergies.
