To implement the right maintenance regime, you need to understand the type of sauna you have, as each has unique requirements due to their differing heating mechanisms.

Traditional Steam Saunas

Traditional steam saunas, also known as Finnish saunas, work by heating the air inside the room. They typically have a heater, often electric or wood-burning, that heats a collection of rocks. Users pour water over these hot rocks to produce steam, rapidly increasing the room's humidity and temperature. Due to the high humidity, proper ventilation is crucial to prevent moisture damage and mold growth. The interior often features wood surfaces and wood penetrating oil, which absorb heat and humidity, requiring regular treatment and cleaning to prevent damage.

Infrared Saunas

Infrared saunas represent a newer technology, offering a different experience. These saunas use infrared lamps that emit light waves directly absorbed by the skin, heating the body without significantly increasing the air temperature. They operate at lower temperatures than traditional saunas, typically between 120°F and 140°F. Infrared saunas have lower humidity levels, which affects the type of general maintenance needed. The reduced moisture means less risk of mold and mildew, but the heaters and other electrical components still require regular checks. The materials used in infrared saunas, often different types of wood or even synthetic materials, may have specific cleaning requirements to avoid damage from cleaners or excessive heat.

how to clean your sauna at home

Maintaining the hygiene and longevity of your sauna requires a consistent cleaning routine. This section details the daily and weekly tasks that should be performed to keep your sauna in optimal condition.

Daily Tasks: Ventilation and Surface

Ventilation

  • Purpose: Proper ventilation is crucial to prevent moisture buildup, which can lead to mold and wood rot.
  • How to Ventilate: After each use, leave the sauna door open for at least 30 minutes. If your sauna has vents, ensure they are open and unobstructed.
  • Additional Tip: Consider using a small fan to circulate air and expedite the drying process.

Surface Wiping

  • Materials Needed: Use a clean, dry microfiber towel for best results.
  • Technique: Wipe down benches, backrests, and other surfaces where sweat and moisture are likely to accumulate. Pay special attention to areas around the heater and door where moisture can be more prevalent.
  • Frequency: Perform this task after every sauna session, once the surfaces are cool enough to touch.

Weekly Tasks:  Sweep or Vacuum

Equipment: Use a soft-bristle broom or a vacuum cleaner with a brush attachment to avoid scratching the wood.

Process: Gently sweep or vacuum the sauna floor, focusing on areas beneath the benches and around the heater where dust and hair tend to accumulate.

Additional Care: If your sauna has a removable floor mat, take it out for cleaning. Shake it outside and wash it according to the manufacturer's instructions if it's washable.

Check for Damage

Inspection Areas: Look for signs of wear or damage on wooden surfaces, heater elements, stones, and door hinges.

Wood Surfaces: Check for splinters, cracks, or discoloration in the wood. This can indicate moisture problems or the need for sanding and resealing.

Heater and Stones: Inspect the sauna heater for any signs of rust or corrosion. Check the stones for cracks or breakage and replace them if necessary.

Door Hinges and Seals: Ensure the door closes properly and the seals are intact. Loose hinges should be tightened, and damaged seals should be replaced to maintain heat efficiency.

Deep Cleaning Your Sauna

Deep cleaning of your sauna is vital and should be conducted every three to six months, depending on its usage frequency. This process is crucial for eliminating bacteria and ensuring the longevity of your sauna's wood and heating elements.

Materials Needed

  • Mild, Non-abrasive Wood Cleaner: Use a mild cleaner specifically designed for most saunas. Do not use harsh chemical cleaners.
  • Soft-Bristle Hand Brush or Non-abrasive Sponge: To avoid scratching the wood surface. If your sauna is located outside, you can use a pressure washer to clean the exterior wood.
  • Microfiber Towels: For effective and scratch-free cleaning.
  • Bucket of Lukewarm Water: Hot water can warp wood over time.
  • White Vinegar (Optional): For natural disinfection and maintaining your sauna clean.

Step-by-Step Cleaning Guide

  1. Cool Down: Wait until the sauna is completely cooled to avoid heat damage while cleaning.
  2. Surface Preparation: Remove all accessories for thorough cleaning.
  3. Damp Wipe: Use a damp cloth with a mild wood cleaner to gently clean wooden surfaces. Avoid over-saturating the natural wood or cedar wood.
  4. Spot Cleaning: For tough stains, use a soft-bristle brush dipped in a cleaning solution or bleach solution, scrubbing gently in the direction of the wood grain.
  5. Rinsing: Use a separate damp cloth to remove any soap residue. Excessive water can damage the wood, so ensure the clean cloth is only slightly damp.
  6. Drying: Allow the sauna to air dry, or use microfiber towels for quicker drying. Proper drying prevents moisture damage.
