Brosse à joints

Starwax's joint brush is sold in France on Amazon and comes packaged in a cardboard box with a plastic outer sleeve. The brush features stiff plastic bristles mounted on a sturdy handle, making it efficient for scrubbing grout and tile joints to remove cement, mold, or dirt. However, the plastic bristles may wear quickly with heavy use, and the tool is unsuitable for delicate surfaces such as polished stone where it could cause scratching.
