Tap water is filtered to meet national quality standards and is safe to drink, but it still contains minerals. When it dries on a surface, those minerals are left behind as spotting and water marks because they're too heavy to evaporate. We remove these minerals first, so the pure (demineralised) water evaporates completely, leaving no marks. Ultra-pure water also readily absorbs the dust and dirt found on glazing. We apply it with a soft brush, rinse again with pure water, and leave the glass to dry naturally to a speck-free finish.
