Why is the ice from your ice maker blue?

Answer 1

blue ice color can only be made by blue toilet cleaning soluions that have been frozen, food coloring will not freeze throughout the water and create solid blue ice like the toilet cleaner. The chemicals in toilet tank cleaners will. Other colors like rust or yellow ice comes from the same souce and spider ice are a conditions that occurs in a home when the ice maker will draw water for ice and the house water presure is low so the ice maker will draw from the toliet tank usally at night. the home has a toilet fill vlave conected to the cold water line and acts like a straw, the is because the homeowner does not have a code listed or mostly china knockoff fill valve in their toilet that are not anti siphon. The best way to not have an issues is to buy code listed valve, the most popular valve in Home Depot and lowes is the fluidmaster that also has this same issue when the valve is older than 5 years and the interior gaskets fails. if you are expericeing ice of a differnet color ask any plumber who can remidy with a toilet valve replacment

Answer 2

Ice makers that produce blue ice often use a special filtration system that removes impurities from the water, resulting in a clearer ice that may appear blue due to how light is reflected off it. The lack of impurities in the ice can also affect its color perception to the human eye.
