I am in the process of stripping down and "improving" my Mortimer. I have degreased all the bits fine, except the copper chimmney cap. It had over time gone black (I know that regular cleaning of it would have prevented this, but its too late now!!) I have tried soaking it overnight in degreaser, in thinners, scrubbing it in water, all to no avail. Any ideas please, other than getting a new cap!!!
Thanks
