To take full advantage of its benefits, A spa must be properly and regularly maintained, as it's a highly favorable environment for bacterial growth. This means maintaining balanced water at analyzing water quality and cleaning your equipment. Here are some practical tips for you to follow at home.

How to properly clean a spa
Depending on use, we recommend cleaning your spa every week or every 2 weeks. When it comes to draining your spa, we recommend quarterly drainage. To winterize your spa, you'll need to follow a particular method.
To preserve good water quality and keep the hull clean for as long as possible, it's strongly recommended that every bather wash before enjoying the spa.
Clean hot tub filter
The quality of spa filtration is crucial to maintaining water quality. The filtration system retains all impurities deposited in the water (hair, sunscreen residues, etc.).
There are several categories of filters ideal for spas (filter cartridges, sand filters for swim spas) which need to be cleaned according to how often your spa is used.
Most spas are fitted with cartridge filters that can be cleaned with a jet of water. Empty the filter regularly and rinse it with clean water.
The filters should be cleaned after each swim to remove hair and other impurities from the water.
Also remember to change your filters regularly, as they have a limited lifespan, to maintain optimum efficiency.
Clean the spa shell or cover
It's not unusual for mold stains to appear on the inside of the cover. This is usually a sign that the water has not been sufficiently treated. You should therefore check its condition regularly, and clean it if stains appear. In this case, remove the cover and lay it flat. Then remove the mildew using a stiff-bristled broom, water and diluted bleach.
To clean your spa shell, simply use clear water and a damp sponge. Spa cleaning products are commercially available, without soap or detergents. You should always check that the products are compatible with your spa by following the manufacturer's instructions.
Brush the water line
The waterline is often the most difficult part of the spa to clean, because it's where greasy residue collects, but it's also the most visible! Use a special spa waterline cleaner for simple, effective cleaning. You can also slightly lower the water level for better visibility, by switching off the power supply beforehand.
Empty and rinse the skimmer
Check the basket or filter bag regularly, empty the contents and rinse with water. This operation can be carried out after activating filtration.
Special case: cleaning an inflatable spa
If you have an inflatable spa, it's best to change the water once a month. To clean the liner, you can use a soft bristle brush or a magic sponge. 24 hours before draining, you can pour white vinegar into the hot tub to remove all traces of limescale. Finally, leave to dry in the sun or use a wet vacuum cleaner until no trace of water remains. You can then deflate it and store it with its protective cover.
Drain your spa quarterly
Every three months or so, we recommend changing all the water in your spa. This will allow you to thoroughly clean your spa's equipment, including the tank and pipes.
Cleaning spa drains
Les canalisations du spa doivent être nettoyées avant la vidange, en ajoutant des produits spécifiques. Se référer au mode d’emploi. Faites fonctionner la pompe de filtration pour faire circuler le produit ainsi que les buses de 10 à 15 minutes.
Couper l’alimentation électrique du spa.
Drain spa water
This involves draining all the water from your spa, preferably down the drain. Follow the manufacturer's instructions. It is not advisable to pour the water directly into your garden, as it contains active chemicals that could damage flora and fauna. When the tank is empty, clean the entire spa: tank, cover and water line. Then rinse thoroughly to remove all traces of product. Use a wet vacuum cleaner if necessary.
Dismantle and clean equipment
Start by dismantling all accessories (headrests, filters) and cleaning them separately in hot soapy water using a cloth or soft bristle brush, following the care instructions. This will enable you to clean them more effectively and, above all, access the most inaccessible corners of the spa.
Clean the filter
You should also thoroughly clean your filter once or twice a year. After disassembly, immerse it in a bucket or basin of water with a suitable cleaning product (white vinegar, diluted bleach, etc.). Leave it to soak for half a day, then rinse thoroughly with clean water. If, after this operation, your filter is still not clean, it must be replaced.
Refill / renew water
Once the tank is rinsed and dry, you can put your spa back in the water. Reinstall the filters, then heat up the water. Finally, add your usual disinfectants.
Protect your ICO Spa
During this draining operation, you can place ICO Spa in a bucket filled with spa water. You'll have to ignore the measurements, which will continue to be taken.
