How do steam cleaners work?

All steam cleaners work by heating water until it boils, thus creating steam. This steam is very effective at cleaning surfaces as it’s able to get in to cracks and pores that may not be accessible to normal cleaning cloths. The steam loosens dirt and grease, which can then be more easily wiped away.

 Cleaning in this way is not just effective, but it also removes the need for harsh chemicals. This can be especially beneficial for households with babies or small children who like to put things in their mouths, as well as anyone whose allergies are affected by strong detergents.
