Infrared saunas are amazing for health and relaxation, but to keep them fresh and safe, regular cleaning is a must. Sweat, body oils, and even bacteria can build up if your sauna isn’t cleaned properly. 

The good news is that cleaning your infrared sauna is simple and doesn’t require harsh chemicals. You can keep it clean with natural, eco-friendly products—and a bit of consistency.

Why It’s Important to Clean Your Sauna

Cleaning your sauna isn’t just about making it look good. When you sweat, toxins, oils, and dead skin cells are released. If left behind, they can stain the wood, create odors, or even lead to mould. Regular cleaning also helps your sauna last longer.

Dust or moisture buildup can damage the wood or affect the performance of the heaters. A clean sauna is a healthier, more enjoyable one.

What to Do After Each Sauna Session

After every sauna session, do a quick wipe-down while the sauna is still warm:

• Use a soft towel or sponge to wipe benches, backrests, and walls.

• You can use plain water, or make a simple natural cleaner with 3 parts warm water and 1 part apple cider vinegar.

• Lightly spray surfaces and wipe clean.

• Leave the sauna door open for 15–20 minutes to let it air out and dry completely.

Weekly Cleaning Routine

About once a week (or every 5–7 uses), do a more thorough clean:

• Mix equal parts vinegar and water or use water with a few drops of mild soap.

• Wipe down all surfaces, including benches, walls, and the floor.

• For stains, use a non-abrasive sponge and gently scrub in circles.

• Avoid bleach or strong chemicals—they can soak into the wood and release fumes when heated.

• Add a few drops of tea tree or eucalyptus oil to your cleaning solution for a natural, pleasant scent.

Monthly Deep Cleaning

Every month, take some time to clean areas you might miss during weekly wipe-downs:

• Vacuum or sweep the floor, under benches, and into corners.

• Wipe under the benches and in crevices with your vinegar solution. Use a soft brush if needed.

• Clean high-touch areas like door handles and control panels with vinegar or rubbing alcohol.

• Dust off the heaters with a dry cloth or soft vacuum attachment. Do this only when the sauna is off and cool.

• Wash towels or floor mats you’ve been using in the sauna. If you use a wooden floor grid, wipe it down too.

Preventing Mould Naturally

Mould loves damp, unventilated wood. To prevent it:

• Always let the sauna dry completely after use.

• Spot-clean any mould with a stronger vinegar solution (1:1 with water).

• You can also use tea tree oil, which naturally fights fungus.

Extra Maintenance Tips

• Sit on towels: Place a towel on the bench and floor during use to catch sweat.

• Avoid varnishes or paint: Interior wood should be left untreated. Heat can cause coatings to off-gas harmful fumes.

• Clean the exterior occasionally: Just dust or wipe with a damp cloth.

• Glass panels: Use a natural vinegar-water mix to clean cool glass surfaces.

• Accessories: Wipe down backrests, footrests, or lamps with your regular vinegar cleaner. Follow care instructions for removable fabric items.
