How to remove hard water buildup from washing machine
To clean a washing machine of limescale and grime build-up you will need two ingredients, vinegar, and baking soda. For top-loading washing machines, fill up your washing machine with hot water on the longest cycle with no clothes in the washer. Depending on your washing machine size, add about 250ml of vinegar, close the lid and let the washing machine run for a few minutes. Open the lid and add 30g of baking soda, shut the lid once more and let run for a couple more minutes. Once that is complete and all the ingredients are mixed together, open the lid and let the water mixture stand for about 30-60 minutes. You can dip a cloth or a sponge into the vinegar and baking soda water to wipe down the rest of your washing machine. Once you’ve waited long enough for a good soak you can let the cycle finish and wipe out the bottom and sides of the machine of any leftover residue.
For front-loading washing machines, mix baking soda with a bit of water and add it to your detergent container. Pour the vinegar into the drum and run a washing cycle at the highest temperature. When the cycle has been completed, use a cloth or a sponge to wipe the washing machine clean.
