I would like to help

I think she mean cleaning the bubbles with the korean text... so then she can add the translation in english

and you can do it with photoshop or any similar software :D

Where can I contact the one who translates :o I would also like to help hehe

I'm pretty sure she meant grammatical errors (like you said). There were many. I can totally understand that being an issue when you're translating and putting out the chapter asap on top of being busy lol

This is her mangago page - http://www.mangago.zone/home/people/149131/home/

Cleaning in scanlation refers to removing the original text and redrawing when needed. Proofreading is checking for grammatical mistakes and typos.

Ahhh I see
