Goldentouch surface prep is crucial, I agree. We use a combination of ultrasonic cleaning followed by an acid dip to ensure the surface is ready for plating. Also, we've found that the quality of the gold used can vary significantly. We've switched to a supplier that provides higher purity gold, which has made a noticeable difference. Does anyone have recommendations for gold suppliers in China?
