Dust contains hidden nasties such as dead skin cells, dried saliva and decaying insect waste. These tiny particles are food for house dust mites and make the surfaces in your home unclean. Mr Sheen with dust trap technology picks up 2 times more dust than using a dry paper towel. The unique formula acts like thousands of tiny magnets, attracting hidden nasties with every spray and because it's Mr Sheen, it will leave your surfaces with that rewarding smear free shine and fresh polish fragrance.
