Because most experience and knowledge in cleaning have been obtained by suppliers of proprietary processes and formulations, these sources should be consulted before setting up a cleaning process.

Electroplated articles are used in many industries such as the marine, automotive, plumbing fixtures, and appliance industries. For more specific safety precautionary statements see Sections 11 and Historical Version s – view previous versions of standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Alkaline chelated derusting and cleaning solutions, alone or with sodium cyanide, used as a soak or electrocleaner, are often preferred before electroplating on ferrous alloys.

These stages are discussed in three parts:. Alkaline chelated derusting and cleaning solutions, alone or with sodium cyanide, used as a soak or electrocleaner, are often preferred before electroplating on ferrous alloys. Often, depending largely on the amount and type of soil on the workpieces as received, one or more of these stages may be eliminated or modified.

It should also be understood that while these procedures are broadly applicable, particular substrates may require certain specific cleaning procedures. Various metals are electroplated for decorative or engineering finishes.

The choice of these procedures must be based on a knowledge of the metals to be cleaned and of the soils to be removed. Electroplated articles are used in many industries such as the marine, automotive, plumbing fixtures, and appliance industries. Part I —Precleaning use of a solvent, emulsion, or alkaline spray to remove the bulk of the soil. Part III —Final electrocleaning, to remove trace solids and especially adherent impurities. Part IV —Trouble shooting. The common electroplates applied are usually copper, nickel, and chromium for decorative and functional uses.
