Overview

A washing machine leaving marks on clothes can ruin your laundry. This guide covers cleaning and fixing the issue.

Step-by-Step Fix

Safety & Preparation

Before beginning any repair, ensure you have isolated power or water supplies. Clear your workspace, gather standard hand tools, and wear appropriate personal protective equipment (PPE).

  1. To begin, purchase a dedicated washing machine cleaner from your local supermarket or hardware store. Follow the product instructions precisely, typically by pouring the cleaner into the detergent dispenser or directly into the drum, then run an empty, hot wash cycle (e.g., 60°C or 90°C) without any clothes inside to deep-clean the machine.
  2. Consider if you might be using too much detergent; excessive suds can leave residues on your clothes. Always check the detergent manufacturer's recommendations based on your water hardness and load size, and try reducing the amount slightly for your next few washes to see if the marks disappear.
  3. Pull out the fabric softener dispenser drawer and thoroughly clean it with warm soapy water and an old toothbrush. Pay close attention to any mould, slime, or solidified softener build-up, as these deposits can be dislodged during a wash cycle and stain your clothes.
  4. Before loading your next wash, carefully inspect the washing machine drum for any stray items, foreign objects, or grime that could be rubbing off onto your laundry. Common culprits include forgotten tissues, coins, hair clips, or even pet hair clumps, so remove any visible debris.
  5. Once you've completed the above checks and cleaning, load a small test wash with a few items you don't mind potentially getting marked, such as old towels. After the cycle finishes, check these items carefully for any new marks before washing a full load of your regular laundry.
