Clean Copper Pipes and Fittings

What happens here

Use mesh-style sanding cloth to clean the exterior of the copper pipe. This type of cloth is preferred over sandpaper as it doesn't clog with copper debris, allowing for longer use. For the interior of the fittings, use a fitting brush. Ensure both surfaces are shiny and free of any oxidation or impurities for the solder to properly flow and create a strong bond.

Goal: Prepare copper surfaces for soldering by thoroughly cleaning them.
