how to remove lime scale..

from bottom corners of an aluminum shower door (and the mounting rails, etc). the shower is on a marble floor. since most things that dissolve lime will at the least kill the finish - or maybe dissolve the stone - i've held off until now..

Lime Deposits on Marble

Marble is limestone, so anything strong enough to remove lime deposits from marble would tend to take its toll on marble. It is important to use products specifically designed to clean marble such as: marble cleaners, marble sealers and marble polish. There are non-acid cleaning products for natural stone. Stone Care International Products are highly recommended. Go to www.stonecare.com to view their problem solving products as well as products for cleaning, sealing,, polishing, and maintaining marble.

Wiping shower and shower door after each use with chamois or squeegie tends to prevent scum and mineral deposits. Metal should be wiped dry with soft cloth. The Bath Enclosure Manufacturing Association endorses the use of Comet Nonabrasive Bathroom Cleaner for cleaning of glass and anodized aluminum. Avoid glass cleaners and harsh abrasives and steel wool, as these can damage shiny protective coating. Once coating is damaged, the metal tends to corrode and what appears to be white rust develops on metal. This is very difficult to remove.

The Aluminum Association warns against the use of harsh acidic or alkaline cleaners because they may destroy the finish. Use solvents with care as they may stain the finish. As with all household cleaning remedies and products, a test area should always be done first to test for ill effects.

Plain tap water, which is too acidic or to alkaline, can damage glass & metal by making it appear dull, discolored, and corroded. Once etching of glass has occured, it is irreversible. This is what happens to glassware in the dishwasher that becomes dull. Any chemical that can remove mineral buildup on the surface of aluminum can damage the coating. The only way to avoid mineral deposits on aluminum is to wipe dry after each use. There are also a variety of commercial cleaners used for aluminum surfaces on boats and automobiles which may help clean extremely dirty aluminum. Do not use commercial household cleaners on anondized aluminum. Keep sealed with a coat of auto wax to prevent corrosion and etching of finish.
