Here are two situations in which people should hire an upholstery cleaning expert.
They've purchased an antique upholstered furniture item
If a person purchases an antique upholstered furniture item, they should arrange for it to be sanitised by a cleaner. They should do this, even if the furniture does not show any obvious signs of being unclean (such as having big stains or a noticeable odour). The first reason for this is that a piece of antique furniture that was made several decades ago may be harbouring bacteria, even if it looks reasonably clean.
