Bathroom cleaners are usually liquid, gels or foams and can remove limescale and soap build-up without scratching your taps and surfaces.
Some are bleach-based or contain anti-bacterials for those times when you want extra hygienic cleaning.
Cleaning with a regular bathroom cleaner is already very effective in removing germs, such as infectious bacteria, viruses and moulds.
Bathroom cleaners are usually liquids and often come in spray bottles. They are also available as aerosol foams.
