Brillo-Method
The first method I will show you is probably the cheapest, and maybe the most available way to polish your internals. This method is the “Brillo-Method” in which you will be using nothing more then water and your common “Under the Kitchen sink” Brillo pad. This does take a bit more time and effort depending on how “dirty” the internal shells are. The best part about this method is that it eliminates the need to follow up in repeat steps.
Materials
Brillo Pads
Water (Bucket, Tub, Sink, w/e)
WD-40
Paper Towels
Time (The more time you take with this the better)
1.) Find your stash of Brillo Pads (or go to the store for some)
2.) Fill the sink with warm water (hot/cold makes no difference) Pick up your Brillo pad and clean the inside of the receivers in a front-back/back-front method only. Follow the same movement as though the rear/front bolt were moving inside.
You will focus mainly on the areas that the front and rear bolt make contact with. You can choose to clean the area that the powertube sets as well, it makes no difference.
3.) After you have cleaned all of the over-spray off the internal shells, rinse them clean…
