We have been running a number of tests recently in the lab after getting some feedback about cutting performance decreasing after working with MDF.
We can confirm that cutting MDF does cause an accelerated dirtying of the lens. There is a significant buildup of residue from this material which in-turn causes the cutting performance to decrease.
During last week we have devoted some time into a simple and safe (on the lens) cleaning process. We have decided on the use of a clever product called a ‘lenspen’ to do most of the cleaning work. We have these on order and will be supplying a ‘lens cleaning kit’ very soon with the required parts. There will also be very specific instructions on the cleaning process.
In the meantime, please do not attempt to clean your lens unless you know exactly what you are doing. Any scratches or damage to the surface coating will be permanent.
