<div>Dear Colleagues,</div>
<div><br>
</div>
<div>What would you recommend for cleaning this Au sputter target that has been partially coated/contaminated with other materials? There are probably a few material coatings on the target, before this was found out. Sputtering the materials off, or sand blasting
will waste a lot of gold. Thanks in advance.</div>
