These outfits use some type of cleaning compound and process to achieve the results. The process seems to be a guarded secret. Has anyone out there had the opportunity to work for these outfits and obtain some insight to what is going on in the process.I can only guess the process involves a liquid bath and rinse with a water pic type device and sonic drying.Any solutions on removing Haze.[/QUOTE]</p><p><br /></p>
