Just a question to the REMEs, 'smiths and metalworkers here:

If you don't have access to bead-blasting, ultrasonic cleaning and other light industrial processes for cleaning metalwork (in UKicon you can't just leave firearms parts with your local workshop...), whats the best cleaning solvent to leave a metal surface suitable for a phosphating-type paint such as Suncorite?

Is a solvent such as methylated spirit, white spirit, kerosene, alcohol, cellulose thinners, etc suitable, or do these leave a surface residue?

I get a reasonable result by cleaning the metal with strong paint stripper, but wonder if an acid or alkali solution such as caustic soda might be better?

Was there a "field" method of ensuring good suncorite adhesion?
