Get rid of those unwanted water spots and make towel drying a thing of the past. Water spots occur because all water is full of minerals, like calcium, magnesium, sodium, and various other dissolved mineral salts. When water evaporates, it leaves these minerals behind on your vehicle in little rings that are called water spots. Eventually, these minerals etch auto paint and require compounding to fix. With a De-Ionizing System you never need to worry about water spots again when washing your windows, vehicle or RV. The CR Spotless cleans water of its minerals leaving you with pure clean water. The whole process works by taking the dissolved mineral solids that are either positively charged cations or negatively charged anions and passing them through the exchange resin in the CR Spotless System that replaces cations with hydrogen. This exchange produces acids that are neutralized by anion's in the exchange resin. The result of this process is hydroxide and hydrogen plus hydroxide equals pure, clean water. We have different size De-Ionizing Systems available and resin to refill your system to get the most out of your water. If your not sure what size De-Ionizer or resin is right for you, Please Contact Us we would be pleased to assist you.
