This general purpose brass brush is for scrubbing nearly anything off of the metal parts of your coffee equipment and espresso machines. It's ideal for cleaning off tough mineral buildup, oxidation, and miscellaneous residues from metal fixtures. This brush is ideal for the softer brass fittings of an espresso machine, like the dispersion plate inside the group. The brass brush won't scratch this brass plate. (The Steel Brush will! Don't use it for this.)
This brush has a sturdy plastic handle, and is for general use on Brass parts in your coffee and espresso equipment. This brush is larger than the others and will not fit up into the group, but can be used to clean many other parts of your equipment. The brush is 8.5" long, and has a linear brush surface of 3". See our article on Cleaning an Espresso Machine for more on this.
