How many disinfectant wipes do I need/how do I know when it’s time to change out my wipe for a new one?

Everwipe^® Disinfectant Wipes are intended for one-time use. Do not reuse wipes as you may spread contamination from surface to surface. Use enough wipes for the treated surface to remain visibly wet for 5 minutes. The number of wipes will vary depending on the total area and the room temperature and humidity. Allow surfaces to air dry.
