Restoration of old locks and padlocks
So how do you restore your old locks and padlocks? With padlocks it is sometimes not that easy. If you can take them apart you can just clean them part by part. If it is a closed body like with the old German padlocks it gets a bit more complicated because you can not reach the inner parts. There is a guy here in Germany who is very good in restoring old locks but I have no idea what he is using and also hadn't had a chance to contact him yet. So I tried to improve my restoration process myself for the last couple of years. Starting with WD40 followed but the Tunap oil MP102 and finally ending with Tunap 366 rust loosener in combination with the cleaner Tunap 117 Tun Solve and the Tunap MP102 synthetic oil again. Depending on the mechanism I also sometimes use the Tunap MP 101 synthetic grease on actuators and ball bearings etc.
So here is how I do it!
Cleaning process:
• I usually start with using Tunap 117 in order to get rid of old oil, grease and dirt. I usually put a lot of that stuff in the lock, shake it a little and then flush it out again. The result is rusty dirty Tun Solve liquid
• After that and if the padlock is rusty I will put Tunap 366 rust loosener on it and maybe also leave it on there for a while so it can take effect
• Using Tunap 117 again to clean it out
• I will repeat this process several times if necessary
• I will also clean the surface with the rust loosener and the cleaner
• (If REALLY dirty I will now put the MP102 synthetic oil on it and let it take effect over night. I will then proceed with the cleaning process the next morning or a few days later)
• I will also clean the keys and their inside according to this process (I would like to use small cotton towels instead but haven’t found a cheap supplier for those yet)
• I also use Q-tips to clean of dirt on the inside or remove dirt of the inner parts
• Toothpicks or a lockpicking hook also comes in handy from time to time. For removing old grease or dirt that is stuck (Be careful, a lockpick might scratch the surface where toothpicks won't!)
• The Sparrows tweezers and diamond tweezers come in handy when removing small stones or metal parts that are stuck in the padlock
• A decent Flashlight should be at hand I am using the Jetbeam M3 and will also be using a NiteCore MT1A soon
Preservation Process:
• I will use Tunap MP 102 on the inside of the padlock after the cleaning process. This will contain the inner parts and make sure the mechanism is going to work properly
• I will use Tunap MP101 for bigger moving parts such as the actuator and ball bearings etc
!!! WARNING: After cleaning the blank material will be exposed !!!
!! Covering it with oil for preservation reasons is necessary !!
I am not a fan of polishing old locks and padlocks. When done accurately there can be very neat results though. Polishing the levers of old safe locks or their inside is fine with me.
So how do you do it? Any suggestions?
Anyone know a supplier for small cotton towels?
