Acid Rain & Window Cleaner

Acid Rain

• Acid rain is an unusually acidic precipitation, which isn't always in the form of rain, that is high in nitric and sulfuric acids. These chemicals occur in the atmosphere naturally, but acid rain becomes a problem when power plants emit high levels into the environment, increasing the natural levels exponentially. When precipitation forms in the presence of these compounds in the atmosphere, particles are trapped in the water droplets and fall to earth.

Hard Water Deposits

• Acid rain itself is acidic, but usually only mildly so. A cleaning nightmare results when the precipitation dries, leaving tough deposits. These crusty deposits, similar to scale on a shower door, remain behind as they are not light enough by themselves to reenter the atmosphere. Most cleaning experts recommend cleaning acid rain deposits exactly the same way you'd clean your shower door.

Glass Cleaners

• Glass cleaners are not very effective on hard water or acid rain deposits because they tend to be bleach- or ammonia-based. These chemicals are highly alkaline. For general cleaning, this formulation is effective, but hard water and acid rain deposits require strong acids to break them up because their bonds are formed differently than common grime.

Cleaners for Water Deposits

• A variety of cleaners are useful for acid rain and hard water deposits. Lime scale remover is specifically designed for these kinds of deposits. Vinegar and citric acid are favorites among home cleaning professionals because they can remove acid rain deposits without harming the environment. Apply both lime scale remover and household acids to large problem areas using a spray bottle. Soak a rag and hold it on small spots. Rinse the glass surface thoroughly after cleaning acid rain deposits.
