Why You Should Never Use Vinegar or Bleach to Clean Your Sauna

It might be tempting to grab what’s under the kitchen sink and give your sauna a quick wipe-down, but here’s the hard truth: vinegar and bleach are not safe for sauna cleaning. In fact, they could be damaging your wood, compromising air quality, and shortening your sauna’s lifespan.

Why Vinegar Is a Problem in Saunas

While vinegar is often hailed as a “natural” cleaner, it’s not ideal for the high-heat, porous surfaces inside a sauna. Here’s why:

  • 🥴 Lingering Smell: Vinegar's pungent odor can be absorbed into cedar, hemlock, and basswood and then reactivated when heated.
  • 🪵 Wood Damage: Acidity can slowly degrade the natural oils in sauna wood, increasing splintering and warping risk.
  • 🧖♀️ Skin & Eye Irritation: In a hot, enclosed environment, vinegar vapor can irritate sensitive users.

Why Bleach Is Even Worse

Bleach (sodium hypochlorite) is a heavy-duty disinfectant, but its use in a sauna is dangerous and destructive.

  • Highly Corrosive: Bleach can break down sealants and compromise the wood’s structural integrity.
  • ☠️ Releases Toxic Fumes: Heat increases chlorine vapor, creating respiratory risks in enclosed spaces.
  • 🧬 Residue Buildup: If not fully rinsed, bleach residue can be reactivated by heat and absorbed through skin.
