Where should you put vinegar in your washing machine?

For a more thorough cleaning (about once a month for hard water to once every three or four months for less hard water), pour a glass of vinegar into the softener tank, then empty the rest from the bottle into the drum. You can then start the hottest program (around 90°C), empty.

Does white vinegar damage the washing machine?
We know: vinegar is rich in acetic acid. As such, it cannot be used on all materials, starting with marble, granite and natural stones which it risks stripping. It is therefore legitimate to wonder if it presents the slightest risk for our household appliances! However, rest assured: vinegar is diluted in water and does not sit on its components long enough to alter them. This therefore means that it will remove limescale and tartar accumulated in the device without harming it. The same goes for joints, which we hear a lot say don’t support it. And yet, this myth is false for the reasons we have just mentioned. These rubber parts therefore pose absolutely no risk!
