Do you really need to clean an infrared sauna?

Yes, you should clean your infrared sauna after every use. Sweeping or vacuuming the floor, wiping down the benches and walls, and drying the sauna will prevent the buildup of dirt and bacteria, and prolong the life of the sauna.

Dust, dirt and bacteria can build up with repeated sauna use, so it’s important for you to clean your sauna as often as possible.

Would you continue to use the bathroom in your home without cleaning it for an extended period of time? Probably not. So why would you treat your sauna any differently?

What type of cleaners should I use?

You should use a mild, non-abrasive cleaner to wipe down the interior of the sauna. Avoid using harsh chemicals or abrasive materials, as they can damage the wood or other materials used in the sauna construction.

We recommend a natural, neutral pH cleaner like the Puracy Natural Surface cleaner. We don’t recommend using acidic cleaners like vinegar or lemon water because those types of cleaners can degrade the wood in your sauna over time.

How do I get rid of sweat stains in my sauna?

You can get rid of sweat sweat stains on the wood in your sauna by wiping it down thoroughly with a non-abrasive cleaner and a damp cloth.

Should I use steel wool or scouring pads to clean my sauna?

No, it isn’t recommended to use abrasive materials such as steel wool or scouring pads to clean the sauna. These can scratch or damage the wood or other materials.

For the longevity of your sauna, we recommend using a damp cloth and a mild cleaner to clean the surfaces of your sauna.

Can I use soapy water to clean the wood and infrared panels?

No, it isn’t recommended to use soapy water for cleaning the wood or infrared panels. Water can leak into the electrical components of the sauna, increasing the risk of fire or electrocution. The soap can also have adverse effects on the wood.

Again, we recommend using a pH neutral natural cleaner with a damp microfiber cloth instead. Here’s a link to our go-to microfiber cloth.
