Only polished away the scratches of the watch band with a polishing machine and chrome polish and then placed after the removal punting existing in the limbs coarser dirt remains the strap in the ultrasonic cleaner.
!!! -> Is important that the water is as hot as possible (as hot as it allows the description of the device - heat previously kettle helps) = 60 ° max in my device.
After the hot water and BioPretta filled.
Can my device with additional heating on in order to keep the water hot. Then with the lid closed (heat should not be able to escape) can go through 2x 8-minute cycles.
After that, the watch strap has really been looking like new. Properly sparkled !! -> It is believed not at what was coming out of the dirt.
In the camps that was a little more difficult, because it has been used several 8-min cycles and strong Nachbürsten with a scrubbing brush.
But nevertheless has become completely clean.
It is also important that after removing the parts that are then carefully rinsed with tap water and then dried or blown dry, otherwise they may quickly begin to rust. (I had the first time I took my bearings from the ultrasonic cleaner and then lies are heraußen wet about 5 hours without rinsing.)
For such extreme gumming and thick accumulations of fat as I had in my bearings but there's quite a different ultrasonic cleaner.
One can apparently even solve rust by ultrasonic cleaning -> Requires also another detergent.
I can only say that this remedy works very well for the manufacturer's things such as glasses and jewelry in any case and even sparked the gumming and fatty lumps on the stock. ---> Therefore, 5 stars from me !!
