There are probably more germs down a plughole than a toilet, but they are cleaned far less frequently. In kitchens grease and food debris that get washed down your sink build up and create a breeding ground for nasty germs such as salmonella. These germs multiply and create smells, and as the debris builds up it can cause slow running or even blocked sinks. In bathrooms hair and soap sludge are the culprits. If you squirt bleach down your sink you kill the germs, but do not remove the debris, so the germs and smells come right back. Buster's range of specialist plughole products can address the specific needs of different problems and areas in your home.
