Good old cleaning methods can still work, but some improvements will help eliminate a larger percentage of these unwelcome visitors.

In addition to serving as havens for infectious agents, some countertop materials can emit radiation and potentially harmful gases. A safety-conscious Washington, DC general contractor is likely to advise you to replace your granite counter because it may be exposing you to radiation and radon, a gas formed from the radioactive decay of elements and which stone emits over time. The quantity released, along with radiation, varies between stone types. In sufficiently high concentrations, radon can contribute to the risk of lung cancer.
