<p>[QUOTE=&quot;verybrad, post: 9559972, member: 37&quot;]So...... I decided to do nothing with the print of the Art Institute other than to lay it in the sun.&nbsp; It got a few hours and I can&#039;t tell any difference.&nbsp; I will mat and frame it as is.</p><p><br /></p><p>I decided to experiment with the other print.&nbsp; I laid it out on a flat enamel surface (My chest freezer top... LOL!). I took a soft brush and brushed it as clean as possible.&nbsp; There really was no mold.&nbsp; After testing a small spot, I drenched the print in isopropyl alcohol.&nbsp; It seemed to do nothing. </p><p><br /></p><p>I blotted it dry and, then drenched it in hydrogen peroxide.&nbsp; It might have lightened it a bit overall but the result was minimal.&nbsp; I rinsed it with distilled water and blotted it dry again. I, then, drenched it in a mixture of 25% bleach and water.&nbsp; It immediately began to lighten overall. I took my soft brush and began to <i>scrub</i> the areas with the worst stains. It did seem to help but the paper began to abrade a bit.&nbsp; I flipped it and drenched it from the back as well. Moved back to the front and drenched it a second time and blotted dry.</p><p><br /></p><p>I, once again, rinsed with distilled water (both sides) and blotted dry.&nbsp; I&nbsp; rinsed it with alcohol (both sides) and blotted it dry again.&nbsp; I kept flipping it and continued to blot both sides until it was pretty dry.&nbsp; I wiped the top surface dry underneath every time I flipped it. I laid a double layered bath towel on top of it and pressed it flat.&nbsp; After a few hours, I removed the towel and let it continue to dry.&nbsp; I rotated sides up periodically, to help it dry evenly.&nbsp; It remained amazingly flat.&nbsp; The next day, I leaned it vertically against a flat surface, as it was completely dry to touch.&nbsp; I left it another day and, then, laid it in the sun (rotating sides up) for a few hours.&nbsp;&nbsp; </p><p><br /></p><p>After being in the sun, the paper rippled just a bit at the edges.&nbsp; I believe it would have dried completely flat had I not put it in the sun.&nbsp; The sun seemed to provide no additional benefit to the cleaning.&nbsp; Here is the result.</p><p>[ATTACH=full]457198[/ATTACH] [ATTACH=full]457199[/ATTACH] [ATTACH=full]457200[/ATTACH]</p><p><br /></p><p>The color lightening is fairly uniform overall.&nbsp; The area I scrubbed with the brush is along the diagonal stain line and is a bit lighter.&nbsp; It did lighten the stain a bit but also started to remove the building images as well.&nbsp; Stains were only lightened by the process overall.&nbsp; The washing did help to remove a crease in the paper.&nbsp; It did not seem to hurt the plate impressions that were fairly light to begin with. </p><p><br /></p><p>Had this print not been so badly damaged, I think the process would have been a benefit overall.&nbsp; As it stands, I don&#039;t think it is ready to mat and frame. I do not know where I go with this now.&nbsp; I may try to research further for additional treatment.&nbsp; My other option is to cut this into two smaller prints that would remove the most damaged areas.</p><p><br /></p><p>I will go over my rationale for treatment in a subsequent post.[/QUOTE]</p><p><br /></p>
