Cleaning with baking soda and vinegar is really helpful and useful, but only if you know when it works effectively and when it doesn't! Combine 1/2 cup of dish soap with 1 2/3 cup of baking soda in a bowl. Also, add 1/2 cup of water followed by 3 tablespoons of vinegar to the bowl and continue mixing to combine the ingredients well and to get rid of any lumps.
