Pick a dry day to begin cleaning your gutters. Make sure you have the necessary equipment including gloves, bucket, garden trowel or gutter scoop, whisk-broom and rag. Inspect your gutters as you clean. Look for corrosion, holes, leaking or loose joints, and missing or bent hangers, and mark the problems with masking tape. The tape will help you find the problem spots quickly when you are ready to do the repairs.
