Before you use your sauna you're going to want to clean it.
I recommend cleaning it upon first receiving it and after it's been in storage.
DIRECTIONS
Follow the directions below to clean your sauna:
Place the sauna in the tub or in the yard near a garden hose.
Spray down with water.
Use an oil soap, a sauna cleaner, hydrogen peroxide, baking soda or tea tree oil.
Scrub down the entire inside.
Rinse.
Wipe down the outside of the sauna with a cloth or sponge.
Your Sauna is now clean.
After cleaning it, dry it out completely to avoid risk of mold.
Direct sunlight is a great way to dry if possible.
Note: The wood will smell amazing like a fresh sauna at this point.
