The bad part of cleaning is that this process has been used far more by people to get rid of cancellations and then trying to sell stamps as unused no gum. Another issue is cleaning or bleaching a stamp to give the appearance of an unused issue
The process I have outlined
Will Not remove a cancel and is Not Cleaning. It only will reverse the process of sulphurization/oxidation of the unstable ink pigments. If anything it makes the cancel standout more.
