Mini Metal Brush

It is a long story of this bike to tell. In short, this is a no-owner-bike. Everyone in the house, including the employers uses it, but no one is willing to clean it. It has been abandoned for a year with flat rear tire until I decided to own it and pimp it last week. I have to admit that pimping a bike is tiresome. The fun side is it keeps me thinking :D Replacing the inner tube of my rear wheel, I can't bear staring at the dirt sticking on the cassette (group of gears) for years. It must be dry grease and dirt compound that hard to remove with a toothbrush. And also the rust inside the rim. Using sand paper on that spot is just giving more pain on your fingers.

Well, a toothbrush shape metal brush for cleaning stove is sold in the hardware store for only a dollar or so. But you know me -- a lazy person who thinks and works hard to enjoy laziness -- I am too lazy to go to hardware store and I prefer make one by myself :D

It is simply a bunch of 24-25 AWG (0.5 mm in diameter). I think it was from a wire mesh.

I cut 15 pieces of 5 inches each. I will fold them into half, so you can make any longer to reach the unreachable spots.

Twist a short piece of wire at the center and fold the wires. So we fold the 15 wires to 30.

I twist the short wire around and down at about one inch (ups.. is it down or up? You tell me :D ). Twist it tight. It is the handle now.

Arrange the wires wider and leave some space between wires.

Now trim the wire one by one so that we have a flat surface at wires' end. Beware of the jumping wires. Always use goggles for safety. Face it downward so that the cut off wires do not hit your face.

Now you can remove sticky dirt and rusty rim. Well.. not that shiny but much better with less power :)
