- vcdimension 7y agoOK, so for some surfaces 4 hours wouldn't be good enough, but for things like letterboxes, door handles & light switches that aren't used too frequently, it could make a difference, and for minimal cost. For example, a postman has to touch many letterboxes on his/her daily rounds, but only once per day.
