A clean washing machine makes a bigger difference than you'd think. Here's the most effective method, plus the mistakes most people make.
Pour 2 cups of white vinegar into the detergent dispenser and run an empty hot water cycle. This dissolves soap scum and mineral deposits.
Sprinkle half a cup of baking soda into the drum and run another hot cycle. This deodorizes and removes remaining residue.
Pull back the rubber door gasket on front-loaders and wipe out trapped grime with vinegar and a cloth. Remove and scrub detergent dispensers.
Clean the outside, door, and control panel with Vibes Multi-Surface Cleaner and a microfiber cloth.
