Disinfectant, solvent for tinctures, and fuel. Denatured alcohol is a different product with bitterants and toxins — it is for stoves and shellac, not bodies.

Shelf life: Indefinite sealed
Container: Glass, cool, away from spark and oxidizers
Grade: 95% (190 proof) or 70% for skin. Never denatured if it will touch a mouth or a wound.

What it does

▸Skin and tool wipe at ~70% (dilute 95% with distilled water)
▸Herbal tinctures (food-grade only)
▸Alcohol stove fuel in a designed burner

Store

▸Flammable cabinet logic: cool, no spark, away from pool shock and permanganate.
▸Child-locked. This is drinkable at high proof and also a fire load.

Hazards

▸Highly flammable.
▸Denatured (methylated) spirits can blind or kill if drunk.
▸70% is a better germ killer on skin than 99% because water helps denature proteins.
