Abstract

Biofilms, aggregates of microorganisms on surfaces, can recontaminate water. This study grew *E. coli* biofilms on household taps and storage containers, then cleaned them using locally-available agents (bleach, boiled water, soapy water, vinegar) and methods (soaking, scrubbing). Bleach, boiled water, and vinegar effectively removed biofilms from taps, particularly with soaking. Soaking was effective for containers, but impractical. The study recommends soaking assembled taps in boiled water for five minutes, but no practical container cleaning method emerged.
