How do I scrape off snail eggs from my fish tank?

I know I asked the question about were these eggs things my fish tank and where snail eggs but many people told me to scrape them off so I don't get an infestation of them so how do I do it|||An old credit card or an algae scraper works best and wont scratch your tank like a razor blade|||A razor blade works best, but if you don't get every single one out of there, you can expect this to be a never-ending battle. The easiest thing to do, if you have room, is to get a small loach. They will seek out and slurp up any snail and eggs you have,
