What sets diatomaceous earth apart is that it works by physical rather than chemical action. One of nature’s richest sources of silica, diatomaceous earth consists of the fossilized remains of hard shelled algae known as diatoms. These fossilised shells are both highly absorptive and mildly abrasive.
