Dr Chemical

Dr Chemical - or Mark Imisides- is fascinated with chemicals. "Everything we eat and touch and are is a chemical. We are made of chemicals and we interact with chemicals every day"

A Ph-D in chemicals means this doctor also knows how best to kill bugs and bacteria. "There are things you can't see. Bacteria, germs, too small to see with the naked eye. And our homes are full of them. There are things that can make you very sick or even potentially kill you."

Today Dr Chemical reveals the 'top five' bacterial hot spots in every house -from bad - to the very worst.

At number five - the hot spot you probably thought was far worse than it is. "The toilet seat - believe it or not this is the least dangerous thing we're testing today for 2 reasons firstly because the parts of your body that touch this don't touch other people and secondly people clean theirs often because they're a prime suspect."

Coming in at number four - the virus you catch here isn't just on-line.

"Computer key board - it might look clean but it's a source of contamination every time someone touches it."

Don't take that call if you want to avoid germs - its number three.

"Telephones - potential source of bacteria because different people touch them but as with the keyboard not too bad because a fairly limited range of people touch them this is probably the best of the lot because with a flat screen its easiest to clean."

Number Two, we all want to get our hands on this - trouble is, so does everyone else.

"Money. Who was the last person who touched this? What diseases did they have? Do you know? Cause I sure don't. This is the number 2 villain in your home."

And topping the list - something we expect to be the cleanest!

"Kitchen sponge. Looks nice and clean doesn't it? Well guess what. This humble looking sponge is the number one source of germs in your home. Why? Because it's full of stagnant water and we all know that germs love stagnant water."

But Dr Chemical has a simple solution for how to get rid of them.

"Mark you're going to show us how to make your own cleaning product but I've got to ask you why have we got the Metho here? Metho basically is just ethanol; it's ethanol with a bit of bittering agent added so that you can't drink it. And that's the basis of many household disinfectants."

And he says making your own household disinfectant is simple. "Get a one litre jug, pour the Metho in up to 700, top it up with water, bit if a stir and there's your home disinfectant. That simple. That's it. People make money from selling this stuff."

That's 70 precent Metho - 30 precent water - keep your sponge soaked in it, and it's always ready to clean, without breeding germs. "I think people will be surprised that such a simple chemical can be so effective and useful and so versatile."
