Hi ECF fans, In this thread we will be discussing maintenance of mechanical mod and its importance. For all mechanical mod users we all know how meticulous it is to maintain a mechanical mod, it is because majority of mechanical mods are made from copper or brass and some parts silver like the Clutch which are prone to verdigris or patina. This basically means that the copper/brass has reacted with oxygen, water, and carbon dioxide in the atmosphere. Why is it important to maintain your mech? Voltage drop. If we don’t clean the mechanical mod regularly the buildup of patina in the connections will increase voltage drop and in turn the mech will have less power output. How do we clean the mech mod? There are many ways to clean a mechanical mod, two of the most popular methods are: Autosol / metal polish Autosol is a chemical that will strip the patina from any metal surface easily and is commonly used, tho it is advised that you pass the mod through a Ultrasonic Cleaner or rinse the mod off as there is still a possibility of the Autosol having a chemical smell that may or may not bother you, not to mention of you accidentally by any chance ingest Autosol it may cause complications to your health. Another popular method is more organic: Salt and Vinegar mixed in hot water Yes hot water salt and vinegar have a very quick and easy way of removing minor cases of patina all it takes is a few seconds of agitation and you have a clean mech, followed buy a nice old school application of some elbow grease (manual labor) polishing. If you don’t mind the vinegary smell that is, we recommend a soap and water bath after to get rid of the smell. To learn more about Mechanical mod please check Here.
