Rubber
Rubber parts aren’t just for dishwashers: rubber gaskets and hoses can be found in your refrigerator and many other appliances throughout the house. Wherever you might discover rubber, it’s best to avoid using vinegar. Rubber is just as vulnerable to the acidity of vinegar as it is to marble or granite. The best way to remove grime from rubber components is with soap and water or a mix of soap and baking soda.
