Using Mirachem 250 in Painting Preparation 

1)                  Clean and degrease item to be painted with Mirachem 500 or similar cleaner.

2)                  Rinse with reverse osmosis water or tap water if reverse osmosis water is not available.

3)                  Soak or saturate the part in Mirachem 250 Rust & Scale Remover at full strength up to a 3:1 dilution with water to remove any surface rust. The addition of heat (110 to 115ºF) may help facilitate the rust removal.  

DO NOT RINSE.  A white powder residue may be present. This is part of the corrosion inhibitor. Rinsing with tap water will remove the corrosion inhibitor and immediately rust the steel part. This residue will not, in most cases cause a problem with paint adhesion. (excess loose powder can be wiped off with a dry cloth) This white residue, depending on storage conditions, will protect parts from rusting for several days before painting.

4)                  When item is fully dry, it can be painted.

NOTE: Mirachem 250 may react with zinc (galvanized), magnesium, tempered carbon steel and some aluminum alloys depending upon temperature and length of exposure. On these surfaces, limit exposure time necessary to remove the rust or corrosion and then water rinse.
