My sister loves to wash with cold water and I just do not think it cleans very well. Her dishes always look cloudy and I am always telling her to wash with hot water but it hurts her hands. So here is a tip for all out there like her….invest in some really good rubber gloves and then you will not have to worry about your hands. You should be wearing gloves when you clean things anyways so you hands do not get chapped or dry especially this time of year.
