80% cleaning vinegar. It's not wise for consumers to buy 80% cleaning vinegar, especially not in a 20-liter container. At this concentration, the acetic acid is so strong that it's unusable. Even a drop on the skin can cause serious damage. 80% cleaning vinegar must first be diluted to a concentration of no more than 20% before it can be used safely. This means that for every liter of 80% cleaning vinegar, 4 liters of water must be added. It's even better to dilute the 80% cleaning vinegar to 9%. This means that for every liter of 80% cleaning vinegar, 9 liters of water must be added.
A 20-liter bottle of 80% concentrated cleaning vinegar is sold almost exclusively to businesses. Cleaning vinegar has an unlimited shelf life, and by purchasing such a large bottle of concentrated cleaning vinegar, you'll have a sufficient supply for a long time. Businesses have adequate facilities to safely store and dilute the cleaning vinegar responsibly.
