The average American home usually has one long gutter or a series of gutters together and
in order to keep them clean, you will need to use gutter cleaning equipment that can be found at the local hardware store or places like Menards, Home Depot, etc. You need a good pair of work gloves, a sturdy long ladder, and long reaching rakes and shovels. After the initial removing of all the debris then you should get some gutter cleaning chemical solution to finish the job. Make sure that this is the type of chemical that won't hurt you or any pets that might be around.
Most people find that they like being able to have a chemical that fits in a container on the end of their garden hose. In this manner, they can use the force of the water to push the chemical all through the gutters and out the down spouting. This makes the final
phase of getting the gutters cleaned and sanitized. You should make sure that you have someone with you when you plan on climbing the ladder for safety sake.
