I’ve used the Cleanator for several months now and it’s become my go-to tool for cleaning the aquarium glass. The steel side removes algae and limescale without leaving scratches, and the sponge side is perfect for light cleaning. It fits well in corners and is easy to handle. Great value for the results.

The double-sided design is very practical. I use the steel side for heavy buildup and the sponge side for daily maintenance. It’s durable and keeps working well even after repeated use. No damage to the glass, which is a big plus.

Works well for removing algae, especially in hard-to-reach areas. The sponge side is soft and doesn’t leave residue. A little less effective on thick limescale, but still better than other tools I’ve tried.
