I used to use it all the time but not anymore

Yes water and its well known anti-bacterial properties

Hand gels don't work very effectively unless you have washed your hands first apparently.

I only use them at work. Otherwise i normally just wash my hands.

Cuda is ill today - goes to show that killing all the germs on your hands doesn't stop you getting ill....if anything it makes you more susceptible.

Its other people not using it that makes you ill

You still need to wash you hands before using it. Otherwise it's not as effective.

I always do

I only use hand sanitizer if I don't have access to a basin to wash my hands or I think it will be a quicker way to clean my hands. I always wash my hands after I go to toilet.

I use it when I need it

But I wash my hands more
