How do you remove the bad part?

I use a hot air butane blower to heat the soldered legs of the chip to be removed and lift it off using tweezers once the solder melts

How do you clean the board?

Isopropyl Alcohol works well or electronic contact cleaner will do the trick.

How do you prepare (for) the new part?

Solder flux pen works well to prepare the contacts or touch up the solder on the board with the tip of the soldering iron.

How do you attach it?

Make sure the surface is clean and fluxed I reheat melt solder with hot air or use a soldering iron to touch the legs.
