Use Aquet® Detergent for hand washing glass and plastic labware. Used in a 1% dilute solution, this aromatic, neutral pH, phosphate-free and biodegradable polyglycol ether will not etch or mar precision glassware. It drains off glassware readily and naturally dries quickly without wiping. For convenience, Aquet® is available in individual pouches that make one gallon of cleaner. For frequent users, Aquet® is offered in a 3.8 liter (1 gallon) bottle with a 473ml (16oz) dispenser bottle. It is also available in a 18.9 liter (5 gallon) size.
