Remove everything from the shed, creating separate piles. Form one pile for items to keep, another for items to throw away and also a pile for usable items that you no longer need that can be donated.
Sweep out the shed interior using a broom and dustpan. If spider webs have formed on the roof of the shed, wipe them away with the broom as well. Discard all debris in the trash can.
Hose off all garden utensils, machinery and other equipment that requires cleaning.
In a bucket, mix a solution of one gallon water and two tsp. liquid dish soap. Dip a rag in the solution and wipe down any objects that require cleaning.
Place all small objects in boxes or storage tubs, clearly labeling the boxes with the contents.
Place all items from the "keep" pile back into your shed, placing items most used toward the front of the shed for easy access.
Place all items from the "trash" pile into the trash can or trash bags and dispose of on trash day.
Package all items that can be donated into boxes or garbage bags and deliver to your local donation facility.
