Using a 1% aldehyde disinfectant the bacterial count was reduced by 84% by scrubbing the floor, by 60% with a wet mop and by 50% with a dry mop. However, two hours after floor disinfection the bacterial count was nearly back to pretreatment when walked on again. Disinfectant mats did not decrease bacterial count on the surface behind them. Plastic overshoes did not influence floor contamination. There was no significant difference regarding the infection rate, in an intensive care unit during a six-month period, between routine floor disinfection and cleaning without disinfectant. It is possible that by doing without routine floor disinfection something like 20 million DM can be saved per year. The World Health Organisation also recommends floor disinfection only immediately after contamination of the floor by infectious secretions.
使用1%的醛类消毒剂，通过擦洗地板，细菌数量减少了84%；用湿拖把拖地，细菌数量减少了60%；用干拖把拖地，细菌数量减少了50%。然而，地板消毒两小时后，再次有人行走时，细菌数量几乎又回到了消毒前的水平。消毒垫并不能降低其后方表面的细菌数量。塑料套鞋对地板污染没有影响。在重症监护病房，六个月期间，常规地板消毒和不使用消毒剂的清洁之间，感染率没有显著差异。每年不进行常规地板消毒可能节省约2000万德国马克。世界卫生组织也建议仅在地板被传染性分泌物污染后立即进行消毒。
