I need to scrape some corraline algae off my starphire glass. My algae free Velcro scraper isn't cutting it, and neither is my hand-held kent marine pro scraper. I'm deathly afraid of using a metal scraper blade and scratching my glass. What are my chances of it scratching?
shouldn't be a problem. I have a metal scraper I used on my glass all the time. I also have used razor blades. acrylic scratches easily, glass not so much... The only scratches I've put into glass was from using a strong magnet and getting sand trapped between it and the glass.
