This coating protects steel or iron from rust, both as a barrier and with an electrochemical reaction. To get this alloying reaction to happen, though, the steel or iron surface has to be prepared; mostly, this means cleaning off the surface. The things that can be found on the work can include everything from fingerprints to cosmoline-type grease, light rust to heavy scale, and sometimes other coatings such as stencil, chalk, spray paints, etc. All of this has to come off. Most of the time, the grease and other dirt is removed with either a dip-tank full of a degreaser, often an acidic (such as Hydronet) or a caustic (such as sodium hydroxide boosted with SB Clean). The other common cleaning method is mechanical, such as a shot-blaster, grinder, or even a file. The choice of the type of cleaning is difficult, since almost every
