If you put Clorox 2 in a bleach dispenser, the Clorox 2 will be dispensed along with the bleach. This can be dangerous because Clorox 2 is a concentrated bleach and can cause irritation if it comes into contact with your skin. If you accidentally put Clorox 2 in a bleach dispenser, be sure to rinse the dispenser out thoroughly with water before using it again.
