I am paranoid about germs and smells especially in the kitchen and i am always on the lookout for products to zap all imaginary germs and foul smells.
I discovered this tip by error. After squeezing tons of lemons for use for baking, i had all these squished lemons. My eyes caught my dishwashing liquid which is always lemon scented and i know that because of the acidic nature of lemons - they can be pretty harsh and strip oils from most surfaces. So i took the squished lemons and ran a whole bunch of them around my kitchen sink and left overnight. The next morning, the sink smelt so lemony fresh and once i rinsed off the lemony residue, the kitchen sink felt brand new - no slick oily aftermath of all the washing up and it was sooooo shiny.
This has become a ritual now in my kitchen and i usually will do this 2 -3 times a week. I have also discovered that 1 lemon cut in 2 halves will more than suffice.
Do not be tempted to try this tip on your aluminium or non-stick cookware - the lemons will corrode the surfaces and if you are like me and spend a pretty penny on quality cookware - there will be tears.
