How often should I clean my ozone sauna, and how?

After every session

Wipe the sauna down with a clean towel and clear the water from under the footrest — the most-skipped step, and the usual reason a sauna does not heat next time.

Every model also has disinfection options, always run with no one inside the sauna. On the Red Light, an automatic ozone disinfection cycle starts with one tap on the screen and runs with no one inside the sauna, between sessions or whenever time allows; the sauna shows a warning for the cycle. Ozone is a recognised disinfectant and the cycle is a genuine feature of the Red Light. It is not a substitute for the wipe-down: an O3 disinfection cycle works in proportion to concentration multiplied by contact time, and organic soil — sweat and skin oils — consumes ozone. Clean first, and let the ozone be margin on top.

Weekly

Clean with soap, warm water and a soft cloth, concentrating on the seat, the doors including inner faces and bottom rubbers, and the floor and footrest. Then run the ozone for 15 minutes with the doors closed with no one inside to clear the chemical trace the soap leaves.

Once a week is a floor, not a target: a sauna taking six clients a day needs it far more often, and your health authority’s rule for shared wet equipment will usually be stricter.

Which products

Soap, warm water and a soft cloth is the method. Beyond that:

• Abrasive pads and scouring cream scratch the shell and display window, and scratches hold soil.
• Bleach, chlorine and solvent cleaners are not part of the method, and inside a hot, wet sauna their residues do not simply disappear.
• Never spray liquid into the ozone inlet, at the door electronics or near the concentrator. Spray onto the cloth.
• Go easy on the door rubbers. Ozone attacks most elastomers, and ordinary rubber and latex perish.
