Sterilising Liquid

I asked a question before, how do British people remove tea stains? And my friend taught me using vinegar is effective. I also wondered how do people sterilise a cutting board? But now I found the solution. The other day, I found this sterilising liquid at the Boots. It says that suitable for baby feeding equipment, nursery, "KITCHEN" and food!!! That's it! That's the one I was looking for! No wonder I couldn't find this, because it was in baby's section. It make sense. I don't have any baby and kids, so I didn't go to the baby's section. Normally, you can find this kind of liquid next to dishwashing liquid at a supermarket or drug store in Japan. So I was fixed on the idea that they are sold in kitchen's section.
