What follows is not a life hack. It is a cautionary tale of chemistry, corrosion, and costly repairs. Here is the deep dive on why Liquid Plumr in a dishwasher is a recipe for disaster. To understand the catastrophe, you have to understand what Liquid Plumr actually is. Most gel-based drain cleaners (like Liquid Plumr) contain sodium hydroxide (lye) or sodium hypochlorite (bleach) , mixed with aluminum particles to create heat.
When you pour it down a sink drain, it reacts with water to create an exothermic (heat-producing) reaction that can reach near-boiling temperatures. This heat melts grease, while the chemical eats through organic matter (hair, food sludge). liquid plumr in dishwasher
We’ve all been there. You open the dishwasher at the end of a cycle, expecting the warm, steamy glow of clean dishes. Instead, you’re greeted by a swampy, foul-smelling pool of gray water sitting in the bottom of the tub. The dishes are filmy. The drain is clogged. Again. What follows is not a life hack
Do not trust TikTok. Do not trust the "life hack" blog that has a photo of a sparkling dishwasher. Trust chemistry. To understand the catastrophe, you have to understand
