Homemade PCB Fixing Ideas Please

I have etched a PCB... almost perfect except for a couple of lines which are joined but shouldn't be.

What is the best way of removing this excess copper post production?


Thanks!

I scrape it away with a craft knife.

use knife or blade to scratch it off. here is another tough idea, take a ear cleaning bud, dip it in concentrated ferric chloride, then rub the unwanted track and wipe it off. i have done this only once,
**broken link removed**

i've done that also a couple of times, if its an easy straight line i just cut it caw/ an exato knife, if complicated, i've just scratched in the line so i can see it throught
clear paint or wax and rescratched it then reetched. has worked good for me so far. i'm learning to tripled check now
