<p>Yes - 70...80 % ethanol in purified water works very well. It cleans well and evaporates quickly without leaving residues.<br>Instead of newspaper, I recommend paper towel (kitchen roll). This is how I clean many tops of insect drawers, for example.<br>Do not close the drawersuntil the ethanol has evaporated completely.</p>
<p>Kitchen roll is an essential tool in collection work :-)</p>
<p>Cheers</p>

<div class="elementToProof" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">Whether 70% ethanol works as a glass cleaner depends on the water. If you use regular tap water, you're likely to find that the minerals in the water will smear all over the glass. Mix it up with purified deionized water, though, and it should work. </div>
<div class="elementToProof" style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">Though it's frowned on, I must say that trisodium phosphate cleans glass (sheet and vessels) like nothing else. A teaspoonful of powder (in the US it's sold as Alconox) in a gallon of warm water is all it takes. </div>
