Fill a 5-gallon bucket halfway with corn. Wrap the 1/4-inch hardware cloth over the top of the bucket. Tie the piece of wire around the rim of the bucket to hold the 1/4-inch hardware cloth over the top of the bucket. The 1/4-inch hardware cloth allow things smaller than 1/4-inch to fall through the cloth; the corn kernels are just big enough to stay in the bucket.
Flip the bucket upside down. Shake the bucket up and down to allow any small debris to shake through the 1/4-inch hardware cloth. Set the bucket down. Remove the 1/4-inch hardware cloth.
Set another 5-gallon bucket next to your current bucket. Have a friend turn on the leaf blower to the lowest setting.
Slowly pour the bucket of corn into the other empty 5-gallon bucket. Have your friend aim the leaf blower at the pouring corn to remove any dust or debris remaining on the shelled corn.
