You would pretty much remove all the Korea words, like taking out the text from the speech bubble and cleaning up and possibly redraw where the sound affects are. It's not too hard and it seems the translator will help :)
Taking out the text from the speech bubble might be easy but I don't rlly think I can redraw the sound effects ┗( T﹏T )┛
Well by redraw I just mean redraw the background the sound effects were covering. Though you could just talk to the translator and tell them what you can and can't do, or ask for help to see if you can get an idea. (maybe just clean the sound effects text and maybe the translator will position the text to cover it up nicely lol)
I wish I could help too but I'm already cleaning for another group (￣∇￣")
I would like to help but I wanna know what cleaning really is. Is that mean clean the korean speech in the bubble or what?
