First, any drip or overspray might damage other materials nearby. Second, the remnants left on the part may attract dust or interact with the intended lubricant. Third, the remnants left on the part might cause long term damage to the part. <br /><br />Any sludge remover has to be checked for possible negative effects. The hydrocarbons that were used to remove sludge from these mechanical assemblies vaporize and release harmful emissions into the atmosphere, as well as having potentially nasty effects on skin or lungs, so they are now prohibited on OSHA and EPA grounds. Even mineral spirits, a light fraction that is a barely adequate substitute for the old solvents, is banned in some areas such as where I live in California due to its effect on the air. <br /><br />Disassembly, hand cleaning, or just flushing with a very light oil along with repeated working of the movement is what works best, even if it takes time. Selectric typewriters, even those just used for typing without any connection to digital electronics, can be loosened with WD40 for a near term improvement but the track record is quite bad once a few months have passed, so that no repair shop or restorer will use WD 40 or any of the similar solutions to free up sludgy pivots and linkages.
