<p>[QUOTE=&quot;BadThad, post: 2681400, member: 17261&quot;]Actually, acetone is a Lewis base due to the lone pair of electrons on the oxygen. However, it&#039;s an extremely weak one so it has no effect on the pH of an aqueous solution.</p><p><br /></p><p>OP - The haze is not from the cellophane, it&#039;s due to the permeability of cellophane and improper storage. In my experience, this haze cannot be removed with the classic solvents, i.e. water, acetone, xylene. I&#039;ve never tried it but I hear MS70 is good for removing haze.[/QUOTE]</p><p><br /></p>
