There are different varieties of chimney brushes available for different chimney types. The two basic types of chimney brushes are wire brushes and polypropylene brushes.

It depends on which type of brush you mean. If you men a brush as in a shrubbery, then the word brush is plural and singular. To be lost in the brush implies that you are in an area that is full of bushes or shrubberies. If you mean a brush that you use in your hair, then the plural is brushes.
