This is for all of you who grow your own potatoes, or buy the ones that still has dirt on them and needs to be peeled.
1. Get a hold of a toilet brush. You need to look for one with a relatively thin shaft
2. Cut the handle off about 20-30cm from the brush head
3. Mount what is left of your toilet brush in a drill. Put your potatoes in a bucket with enough water to cover the potatoes.
4. Do this outside or in your shower; submerse your toilet brush in the water and power up your drill (in that order). Move the drill around in the bucket and watch the magic happen!
