Creating a workhorse cleaner is no achievement if the product corrodes metals. Buffered alkalinity makes PQ® sodium silicates effective in neutralizing acidic soil and emulsifying greases and oils. Unlike other alkalies, however, sodium silicates inhibit corrosion in tin, aluminum, copper, brass, and soft metal alloys and protect china glazes. That's because of their dissolved silica content, a proven corrosion inhibitor. Used in medium- and heavy-duty cleaners or in household detergents, sodium silicates combine detergent cleaning action with protection against corrosion. The detergent props permit products such as
