Abstract
The cleaning device includes a squeeze-bottle with a spout and a brush extending from the spout. A flow restrictor prevents cleaning fluid from being dispersed from the spout to the brush until the bottle is squeezed. The flow restrictor is formed simply by inserting the twisted wire handle of the brush into a tube forming the outlet of the spout. The length of the tube and the twisted wire can be selected to give the desired amount of flow restriction. The device is particularly well adapted for use in cleaning solder flux and other undesirable substances from printed circuit boards after they have been assembled. The cleaning device is relatively compact, inexpensive to make, and simple to use.
