Isn't it such an accessible wet cleaning?
You are right. Cleaning a carpet on snow is an effective and eco-friendly way to combat dust, confirms hygienist Raksana SEVASTYANOVA.
Snow acts as an absorbent. Frost kills many microorganisms and insects, and snow, especially fluffy and cold, absorbs dust well due to its moisture and static electricity.
At the same time, modern vacuum cleaners with HEPA filters, steam cleaners, or professional dry cleaning handle the task just as effectively. Often, it is easier to take the carpet (if there is one) to dry cleaning or call specialists to the house. Perhaps this explains why carpets are cleaned on snow in yards less and less often.
