silkscreen pcb chemicals
Hai Samath. Practically it is not possible to remove only the Silk screen print. If you clean the silk screen with a chemical, it will also affect the solder masking which is beneath it. This will expose the bare copper which will start oxidising in coming days. If that is ok, You may use diluted nitric Acid which is available with gold smiths. But you are at your own. Be cautious as even diluted Nitric acid used in gold industry will be strong enough to burn a hole in your skin. For ease, you may also scratch the misprint with a knife which will also remove both prints. Good luck.
