Resolution

Grey marks on laundry are usually caused by detergent residue, a dirty washing machine, overloading, or incorrect detergent use.

Washing frequently at low temperatures (40 °C or below), combined with enzyme-based detergents, can lead to build-up of mould and greasy residues inside the drum, seals, and pipes.
This can result in:

• marks or stains on clothes
• unpleasant odours
• blocked components

How to fix grey marks on laundry

1. Regularly perform a maintenance wash using a washing machine cleaner.

• Empty the Drum
  Make sure the washing machine is completely empty - no clothes or laundry items.
• Select a Hot Wash Cycle
  Choose the hottest cycle available (usually Cotton 90°C or 95°C).
• Add a Cleaning Agent to the drum
• Run the Cycle
  Start the cycle and let it complete fully. Do not interrupt it.
• Clean the Detergent Drawer and Door Seal
  After the cycle, wipe down:
  • The rubber door seal (check for mould or residue)
  • The detergent drawer (remove and rinse under running water if possible)
• Repeat Monthly
  Doing this once a month helps prevent buildup and keeps your machine fresh and efficient.
