<p>[QUOTE="desertgem, post: 3621255, member: 15199"]For ez-est, I start with a low % as it is extremely strong fresh and full. I start at about 10% dip and 90% water as a use once-throw away solution. At this percentage it may take a large amount of time instead of the 1/2-3 minutes full and you time to decide when to stop, rinse with water, then acetone and air dry as the acetone will carry any microscope water away as it evaporates.Once you learn how long it takes, you can increase the strength to your desire. As said practice on insignificant coins.[/QUOTE]</p><p><br /></p>
