Tried using brush bombs for the first time today. They were about the size of a filbert, or maybe a little bigger but not much. I used three in a bucket of water, tossed in the brushes and let them do their magic. Well the cosmic forces were not with me because they utterly failed. They were in the water for a couple of hours and, while less groddy, they were still pretty dirty. Should they soak overnight?
The brushes are in the dishwasher.
