I have used these for years to scrape the inside of my aquarium glass. The blade will rust eventually, but it’s very inexpensive to replace works much better than the ones they sell for aquariums.

Great product useful for multiple surfaces

Idéal pour nettoyé les vitres et portes patio et autres surfaces comme les comptoirs de granites etc ...

Works as expected. Does exactly what it is supposed to do. Great price. Would buy another without hesitation.

Over the years, I bet I have bought half a dozen of these - they keep growing legs and vanishing. Just pop a construction blade into the plastic handle and scrap till the blade dulls. It is feather light, but the design enable you to really bear down on the blade. I have several pricier scrapers with 3 and 4 inch blades. I often still use this tool to finish up.BTW, the design lets the blade protrude out the sides just a little, so it is great for scraping paint along glazing.Do not expect to see these in hardware or DIY outlets like HD - there is apparently not enough markup for them to stock. Buy several, as I said, they tend to disappear :-)
