I'm looking for info about etching. is it better to use PH up or PH down? The PH up that I purchased says that it is very corrosive and contains potassium hydroxide. How much would you use in a bucket of water?

Looking forward to your comments, Lance

Potassium Hydroxide won't do the trick - try vinegar. Marie
