that won't work. IMHE I have found that the rope losens in a short time causing the tire to slide to fare from the extinguisher.. this allows the toothbrush to slide out of the can and as a result the washing soda doesent get mixed up which leads to a low alk output. to corect this you need to put a couple wraps of duct tape over the rope to secure it good and act as a secondary fastener.

another trick I have learned is to use a aquafresh brand tooth brush, the flexable neck alows it to move and make up for slight vibrations.

hope this helps
