Types of Cleaning Brushes

Brushes come in many sizes, from those that would lightly dust a tiny figurine to those that clean enormous warehouse floors. They can perform a wide variety of tasks, from sweeping debris to cleaning intricate designs on circuit boards. 매트리스청소업체

Medical device manufacturers often recommend a specific brush design to be used for cleaning their devices. Using brushes that are not compatible with sterilization processes increases the risk of cross-contamination and internal damage to the channel.

Handle

The handle of a brush is the part that holds and supports the bristles. It is made of a sturdy material that can withstand repeated use. The handle can be plastic or metal, and both have different tensile strengths. Metal handles are stronger than plastic ones, and they can withstand high temperatures. They are also corrosion resistant.

Stainless steel wire brushes are an excellent choice for corrosive environments. They can be made in several styles and sizes. Some have a narrow head for cleaning confined spaces. Others have a wide head to accommodate larger parts and tools.

Stainless steel is also used as a handle for some types of brushes. These are a good choice for food processing and medical applications. Often they have a smooth, comfortable grip. Some are designed to be easy to hang up for storage. Other handles are made of wood or food contact compliant polypropylene. They have a lanyard hole to enable users to hang the brush when not in use.

Bristles

The bristles of a brush are inserted into the handle and can be made from hair, wire, metal, synthetic fibers or various natural materials. The number and type of bristles is what determines the cleaning capabilities of a brush. Bristles can be trimmed straight, rounded or angled for specific applications such as scrubbing curved pharmaceutical tubes or sweeping dust and debris.

The handle can be made from wood, injection molded plastic, steel or a conductive or static dissipative material like brass. The handle also needs to be sturdy enough to support the weight of the bristles without bending or tearing.

Stainless steel wire brushes are ideal for aggressive deburring, removing rust and surface roughing for prep of epoxy adhesives. Other metal wire brushes include copper, nickel silver and phosphor bronze. These are ideal for electrically sensitive applications and offer good corrosion resistance, fatigue life and conductivity. They are less expensive than stainless steel wire and can be trimmed for specific applications.

Material

A cleaning brush can be made from a wide variety of materials, with each type suited to particular tasks. Some brushes, like those used for cleanroom applications, have a stainless steel wire or static-dissipative acetal handle. Other brushes, such as instrument and small parts cleaning brushes, have their fill material mechanically crimped into a stainless steel or acetal tube inserted into a plastic tapered handle. A double-ended brush such as this can have different kinds of fill material on each end, for example Nylon at one and Hog Bristle or Horsehair at the other. Other brushes are composed of dry-surface-cleaning materials that can be used to remove minute soot particles from an object, such as Skum-X eraser powder and block or Groom/Stick erasers (Elizabeth Moffatt 1992).

For a very light cleaning task, there’s nothing better than a natural soft horsehair or hog bristle brush with a wood handle.

Cleaning

Brushes clean up dirt, grime, food, oil and other residues from surfaces, equipment, tools and machines. They also can be used to scrub and remove stubborn paint, rust, deposits or other substances from metal parts and equipment. Wire scratch brushes can vigorously scrub and remove metal and other difficult-to-clean materials from pipes, tubes, valves, grills and vats.

Ideally, brushes should be cleaned and disinfected on a daily basis. If the brush can be run through a washer disinfector with a thermal cycle, that would be the preferred method. If not, thorough manual cleaning should be performed.

To wash a painting brush, gently dip the tips of the bristles into some cleaning mixture such as Winsor & Newton Artists’ White Spirit or Brush Cleaner and gently rub against lint-free paper towel to work off any remaining colour. When dry, wrap in construction or other sturdy paper to keep the bristles straight and hygienic until you need to use it again.
