Disinfectant & Cleaning Tips for Hot Tubs

Hot tubs offer a luxurious retreat, whether in a commercial spa setting or a private backyard. Maintaining that crystal-clear, inviting water, however, requires diligent cleaning and proper disinfection practices. This ensures not only a pleasant experience for users but also safeguards their health by preventing the spread of waterborne illnesses. In this comprehensive guide, we delve into the best disinfectant and cleaning tips for hot tubs, tailored for spa professionals and hot tub owners alike.

Why cleaning and disinfection is important 

Hot tubs create warm, moist environments that are perfect breeding grounds for bacteria, algae, and other microorganisms. Regular cleaning and disinfection are crucial for several reasons. First, it prevents health risks; bacteria like Pseudomonas aeruginosa can cause skin rashes, while Legionella bacteria can lead to severe respiratory illnesses. Second, it maintains water clarity; the accumulation of contaminants leads to cloudy water, which is unappealing and unsanitary. Third, it prolongs equipment life; regular maintenance prevents scale buildup and corrosion, extending the life of pumps, filters, and other components.

Hot tub disinfection 

Choosing the right disinfectant is essential for effective sanitation. The most common types include chlorine, bromine, saltwater systems, and mineral sanitizers.

Chlorine is highly effective against bacteria and viruses, readily available, and affordable. However, it has a strong odor, can cause skin and eye irritation, and degrades faster in hot water.

Bromine is more stable at high temperatures, has less odor than chlorine, and is effective over a broader pH range. Its drawbacks include being more expensive and slower to dissolve, and some users may still experience sensitivity.

Saltwater Systems offer softer water on skin and eyes, provide continuous sanitation, and require less chemical handling. On the downside, they have a higher upfront cost, require cell maintenance, and may corrode certain materials.

Mineral Sanitizers use natural minerals like silver and copper to inhibit bacteria growth, reducing the need for high chlorine levels. However, they are not a standalone solution and must be used in conjunction with low levels of chlorine or bromine.

Step-by-step guide

Find the right supplies 

Before starting, gather protective gloves and eyewear, a hot tub cleaner or mild detergent, soft cloths and sponges, pH increaser or decreaser, alkalinity adjuster, calcium hardness increaser, test strips or kits, filter cleaner, and a garden hose. Don’t forget that we offer bulk water chemicals for hot tubs for businesses like yours. 

Drain the hot tubs

Begin by turning off the power to prevent damage to the heater and pumps. Use the drain plug or a submersible pump to remove the water, disposing of it according to local regulations.

Clean the shell 

Apply a non-abrasive cleaner specifically designed for hot tubs, avoiding household detergents that can cause foaming. Gently scrub the interior surfaces to remove biofilm, scale, and dirt. Rinse thoroughly to ensure all cleaning agents are washed away, preventing foam and chemical reactions.

Clean the filters

Remove the cartridge filters carefully. Rinse them using a garden hose to spray away debris. For deep cleaning, soak the filters in a filter-cleaning solution overnight. Rinse them again to ensure all cleaning agents are removed before reinstalling.

Inspect the jets

Check for any signs of wear, leaks, or damage. Clean jet nozzles with a small brush if necessary.

Refill 

Fill the tub with fresh water using a pre-filter to reduce contaminants. Filling through the filter compartment helps minimize air locks.

Balance the water

Test the water using test strips or a liquid test kit to measure pH, alkalinity, and calcium hardness. Adjust the pH to the ideal range of 7.4 to 7.6 using a pH increaser or decreaser as needed. Adjust alkalinity to keep levels between 80-120 ppm to stabilize pH. Adjust calcium hardness, aiming for 150-250 ppm to prevent corrosion or scale.

Shock the water

After balancing, add a non-chlorine shock to oxidize contaminants and enhance sanitizer efficiency.

Regularly maintain 

Establish a routine for testing and adjusting chemical levels, cleaning filters, and inspecting equipment.

Maintaining water quality 

Regular testing is essential. Test the water at least twice a week, and more frequently with heavy use. Keeping a log helps track adjustments and spot patterns. Maintain appropriate sanitizer levels—3-5 ppm for chlorine or bromine. Shock the hot tub weekly or after heavy use to eliminate organic contaminants. Rinse filters weekly and deep-clean them monthly, replacing filters every 12-24 months depending on usage.

Minimise contamination  

Encourage users to shower before entering the hot tub to remove oils, lotions, and other contaminants. Limiting food and drinks near the hot tub area helps avoid spills. Using a quality hot tub cover prevents debris from entering and reduces evaporation; remember to clean the cover regularly. Educate guests about proper hot tub etiquette to maintain cleanliness.

 

Always read labels and follow manufacturer instructions carefully. Use protective gear like gloves and goggles when handling chemicals. Store chemicals in a cool, dry place away from children and pets. Never mix chemicals, as mixing can cause dangerous reactions.

Embrace new technologies 

Advancements in hot tub technology can simplify maintenance. Automated chemical dispensers ensure consistent sanitizer levels. Smart monitoring systems provide real-time data on water quality via smartphone apps. Energy-efficient pumps and heaters reduce operating costs and environmental impact.

Wrapping up

Regular cleaning and proper disinfection of hot tubs are essential for user safety and enjoyment. By following these comprehensive tips, spa professionals and hot tub owners can maintain sparkling, healthy water with ease. Embracing routine maintenance, staying informed about the latest technologies, and prioritizing safety will ensure your hot tub remains a luxurious oasis for all who use it.
