Use a vegetable brush to gently scrub away any dirt that remains on the peanut shells. Scoop up a handful of peanuts at a time from the bucket of water and gently scrub the shells as they rest in the palm of your hand. Place the scrubbed peanuts into a colander for rinsing. Repeat this process until all the peanuts have been scrubbed.
You can use a dish-washing brush if you don’t have a vegetable brush handy.
Your hands could be submerged in the water for a long period of time, so consider wearing rubber gloves to protect your skin.
