Why do you need to put dishwashing liquid in the washing machine?

Good question! Normally, dishwashing liquid should not be used in a washing machine—but sometimes people try it, so here’s why it comes up and what you need to know:

Why Some People Use Dishwashing Liquid in a Washing Machine

Emergency Substitute – If you run out of laundry detergent, a tiny drop of dish soap can clean clothes in a pinch. It’s highly concentrated, so just a teaspoon (not more) might seem like a quick fix.

Grease-Cutting Power – Dish soap is formulated to cut grease, so some people think it helps remove oily stains from clothes.

Why It’s Usually a Bad Idea

Excessive Suds – Dish soap is designed for handwashing dishes, not machines. It produces way too many bubbles, which can overflow and damage your washing machine.

Residue – It may not rinse out properly, leaving soap film on clothes.

Potential Damage – Long-term use can harm the washer’s pump, seals, or drainage system.
