Default Re: For those clueless about soldering....

Soldering, adhesive joints and good paint coating adhesion all require a clean surface. The acid flux or rosin flux are both cleaning agents ... best to start with a very clean/dry metal surface.

cleanliness is important for quality welds/brazing .... but in those cases the applied heat assists driving off garbage. Some 'maintenance' welding can be done on dirty/greasy surfaces, but the joint would not meet many quality specifications, because the garbage becomes part of the joint.

It helps to remove the residue of rosin flux after soldering (wait until cool), before sealing. I also oft use silicone RTV as a sealant, then coat with vinyl electrical tape for abrasion resistance.
