Yes, you read correctly! This is not a joke, we actually use the stuff in one of our products!
If you have quantities of mouthwash, or any other household-type, alcohol based, transparent liquid (color unimportant) that is past its "best before" date, and want a way to dispose of it, other than dumping into your local sewer system, contact us, we may accept it, & depending on location & quantity, we may even pick it up.
It is important that the liquid is transparent, and no more toxic than mouthwash if it were to spill on skin or its fumes inhaled. It can be a tinted color, like mouthwash.
NO hazardous chemical mixtures, please!
Also, Please, NO used mouthwash! ;)
