Staining can occur even if your water appears to be clear at first. Once water with iron is exposed to the air, staining may appear on your toilets and sinks. This is caused from iron or magnesium and the longer it sits on your porcelain without being cleaned the tougher the stain becomes and not so harder to remove. Magnesium often contains bacteria, yet the bacteria is not harmful. The easiest and safest way to eradicate the problem is to purchase a water softener or a water purification system. A water softener will take care of the limescale, but the colored water means you have iron in your water. If you have orange staining you r water is coming from a well and you will need the IronMax to remove the Iron and Sulphur. Ask your water technician to provide a free water test and we will take care of all your water problems.
