Cleaning an infrared sauna is a simple process that does not need to be complicated. It’s a good idea to vacuum the floor of your infrared sauna, fairly regularly just for overall neatness. In terms of cleaning the inside and outside surfaces, you want to stick with a mixture of white vinegar and water. Make sure not to use too much water so that you don’t damage any materials that the infrared sauna is built with. Never use chemical cleaners, finishes, or paint on your infrared sauna because the combination with the heat could cause the emission of irritating and toxic fumes.
