So im thinking of this response.
As I mentioned to you on 10 October when you brought this accusation to my attention, that I strongly belief that I am falsely accused of such marks on the glass.
Following our conversation I forwarded on a photo of my brush, the quality and cleanliness of which I presented to on the same day;
As can be clearly seen from the image that the brush is more than fit for its purpose and also in impeccable order. The brushbin question is a streamline 14inch rectangular brush purposely constructed for the use of cleaning glass windows.
I also brought to your attention how I use 6x 1mm jets which provides a constant cascade of water running through the bristles of the brush and therefore preventing any opportunity of blockages within the bristles.
A video of said brush and the cascade of water can clearly be seen from my public videos from my youtube channel NK services which produced to help other window cleaners.;

In addition I also explained how I use hot water, which can be evidenced from my you tube channel.

Which clearly shows the opposite of your claim. Especially in reference to the problem being "endemic" in light that only one pane of glass is showing signs of scratches out of the many panes of glass at your property nor the many which I clean
during the course of a day.
The reason or reasons for the scratches in question should be directed elsewhere and not at myself nor my equipment which is impeccable for its manufactured purpose. As these scratches have only been brought to your attention by the low sitting sun at this time of year.
