Aquarium scrapers with blades

Blade

— the metallic thin edge of the scraper's working part is designed for removing plaque and buildup from glass. This format is especially convenient against tough dirt, with which soft sponges and regular pads handle worse.

Such scrapers are most often used for regular cleaning of the windshield, side walls, and areas where a more careful and precise pass is needed. However, a bladed scraper requires more attention in use to avoid damaging sensitive surfaces and not leaving scratches if used incorrectly.
