I would be cautious using bleach when cleaning. Mixed with certain cleaners it can give off deadly chlorine gas. An example is the chemicals used in toilet cleaners and powdered cleansers.

Avoid Hand Shakes.
Don't Touch... Avoid touching buttons when you can. Like a public phone.
Shopping Carts...When your doing the grocery shopping, wipe down the cart handle with an anti-bacterial wipe before touching it. Many of the super markets provide them in the cart area. Always carry them in your car.
Avoid Handrails... If you don't have to, don't touch the handrails on the escalator. They are full of germs constantly. Same thing with other handrails, only if you need it for balance.
