So after i got my new delfir-chips i decided to make a little how-to: 1) Add Delfilr-chips and the parts you want to clean-up into the tumbler: 2) Add water (water 1:4 delfir chips ratio), and 2-3 drops dish washing fluid: 3) add a bit of random grease to one of the screws (this will give all the parts inside a thin grease cot which prevents it from immeadiatly starting to rust!, you will need to bath them in grease remover before giving the parts to the galvanizing-company!!) 4) Put lock on the tumbler, let it run 🙂 5) wait. have a beer meanwhile. check progress after about 8-12 hours…
