Hi guys, When do you decide that a brush is too worn to use and should be replaced and what are the things you look for that makes you decide new brush. I have attached pics of brush I am currently using, seems worn on one edge.
Thanks for any advice
Bristle deformation is certainly one aspect of when to decide what is the right time to change a brush. If the bristles have worn or deformed to the point where they are affecting your ability to clean the windows in your normal style then this is a good time to change the brush.
However something that affects all brushes of whatever brand regardless of whether they look worn or not is bristle point wear. Even if a brush looks good still after a years worth of work, it usually will have begun to deteriorate in its actually scrubbing and cleaning ability. The points of the bristles will, with regular use, gradually become worn so that they became thinner at the ends. This is not noticed as it is very gradual but when replacing with a new brush it will be quite apparent that the new brush is cleaning more easily and efficiently.
As a general rule any brush after 12 months of regular daily use should be replaced to achieve maximum cleaning efficiency. Lightweight brushes (such as the Xtreme range) will not last as long due to less bristles and lighter stock.
Why is your brush worn on edge more than the other?
This actually affects most users and is because the pole is generally held on just one side of the body - RH side for right-handed workers and LH side for left-handed users. This has the effect for a RH worker of pushing the RH side of the brush harder against the window reveal in general use than the LH side of the brush. This means that with regular use the RH side of the brush and the bristles will become more abraded. Once aware of this effect an operator can adjust their technique to avoid this, however it can also be compensated for by turning the brush by 180 degrees on the socket every few months.
