<p>[QUOTE=&quot;-jeffB, post: 24630330, member: 27832&quot;]As I understand laser cleaning, it relies on the fact that surface contaminants are darker/less reflective than clean metal, and that they conduct heat less effectively both within themselves and into the underlying metal. You can heat them up enough to vaporize them and physically dislodge them without heating the underlying metal enough to change its properties.</p><p><br /></p><p>For PVC residue, though, it&#039;s organic and easily dissolved with acetone or xylene/toluene. It seems goofy to use a laser on it.[/QUOTE]</p><p><br /></p>
