ADA Pro brush hard

Excellent tool - next level of brush hardness

Very well made brush that provides that next level of hardness allowing force to be applied when cleaning hardscape.

Great for Algae

This tool definitely seems a little pricey, but it's worth it. This tool is perfect for getting into small spots or nooks on hardscape that you can't get into with a regular toothbrush or wire brush. Like alot of ADA tools, it's very specialized but great at its job. It was able to scrape algae off my rocks I couldn't remove with anything else.
