A floatable holder for supporting a plurality of brushes having ferrules in a solvent-containing vessel. The inventive holder includes a buoyant block with front and back surfaces and a top surface therebetween. A series of spaced channels each extends through the block from the front surface to the back surface and has access into the channel through the top surface. The channels are dimensioned to loosely receive the ferrules to allow at least partial submergence of brush bristles with the bristles free of non-fluid contact.
