I dont trust myself using a scraper I don't personally have enough experience with them or do I like them at the moment. I saw an alternative to use 0000 steel wool. Only wondering if this is going to be okay ? There is some tough bit of dirt stuck on the glass. Would it be safe to rinse it with water then scrub the 0000 on it? I am going back in a couple days time so need to make the right choice.
