Drano | In Dishwasher

Dishwashers reuse some water during cycles. If Drano doesn't drain completely, toxic residue can splash back onto your dishes. Ingesting even small amounts of this caustic residue from "clean" dishes can cause chemical burns to the mouth and throat.

Introducing Drano (sodium hydroxide/lye or sulfuric acid-based cleaner) into a dishwasher is extremely dangerous and never recommended. It causes immediate chemical damage to the appliance’s rubber, plastic, and aluminum components, generates hazardous fumes, and poses a severe risk of chemical burns to anyone who subsequently opens the dishwasher or uses the cleaned dishes. drano in dishwasher
