Firm bristles, works well to dislodge things in grooves, but one has to follow up with a cloth or sponge to actually clean the loosened stuff out of the track or groove.

Facile d'utilisation entre les fenêtres.Se nettoie facilement sous l'eau.

it works reasonably well though i don't really understand the benefit of the shape as compare with just an ordinary brush. cleaned a very messy rail nicely.

It is good and I found that a little too big for narrow gaps. It still works just be gentle when using it to avoid scratches.

asy to use, gets into tracks, easy to wash up after use

handy unit
