Rusty equipment - why this could be a problem
Of the germs that can lurk in the rust on your garden tools, tetanus bacteria (Clostridium tetani) are by far the most significant. When these bacteria get into an open cut, they can cause muscles spasms (lockjaw), convulsions and death.
How to clean rusty equipment
Rusty equipment can cause some nasty injuries, especially to children playing in the garden. Keep utensils clean by scrubbing them with soap and water. Hand dry them or let them air dry and store them in a cool, dry place. Do not leave tools exposed to rain. Use specifically designed solvents, which are available at most hardware stores, to get rid of rust.
Apply Coca-cola or vinegar with aluminium foil or use fine sandpaper to clean bare metal parts as an alternative and always apply a light coat of cooking oil to the equipment after scrubbing.
