When your working on your bike, how often do you finish with grease all over your hands? Almost every time I bet. The grease and oil that paints itself onto your hands is not only ugly and hard to clean off, but can be harmful when absorbed into your skin. An easy way to prevent penetration of harmful oils and chemicals is to wear thin rubber gloves when doing repairs. Wearing rubber gloves when working in the workshop not only prevents grease damaging your skin but also prevents the need for strong and dangerous detergents to clean your hands. Rubber gloves are usually pretty cheap and are easily accessible from your local supermarket.
