Don't rush to change the washing machine tray that is covered with a hardened coating; it can be washed.
We'll tell you about two cleaning products that will help you do this.
Very effective means against plaque are "Adrilan" and "Sanita anti-rust".
The method of application is simple. Place the tray in a basin, distribute the cleaning agent over the tray, pour boiling water over it, and leave for two hours.
After two hours, clean the tray. There will be no trace of plaque left.
You can also remove plaque from the washing machine tray using regular vinegar.
Previously we told you how to get rid of mold using potassium permanganate and office glue.
