A couple of winters ago I lucked out at a dollar store that had car windshield brush/scraper for $1.25 each. That deep but narrow brush is absolutely PERFECT for getting in between even big cogs whilst the cassette/freewheel is still on the bike. A bit of detergent and that brush and i've hade brown freewheels come up shiny silver.
Cheers
