In lab tests, salmonella, E. coli and staph survived 14+ days in kitchen sponges — 3 days after drying out — and one wipe moved up to 100,000 bacteria to a clean surface; smell and color gave no indication of contamination. Brushes dry faster and carry far fewer bacteria, researchers say.img | 30.07 20:38 | u/andmario_com
