<p>[QUOTE=&quot;desertgem, post: 7807247, member: 15199&quot;]Why use water to rinse off acetone? If you use a high grade of acetone 99+% ( Lowe&#039;s gallon) or 100% ( Organic chem lab) let it evaporate while holding by edges. In real life situations acetone evaporates very fast. Letting water be the last substance ( and a metal object) will lead to spots and obvious marks and is not recommended. Remember acetone liquid and vapors are very flammable.
