Drown your watch
This was the end result after drowning it in the multi purpose detergent for about 30 mins.
This time round I only put in about 1/3 of the cleaning solution and 2/3 of water.
Normally my watch is pretty clean, well as clean as I could get them. Our Malaysian weather does not help, so I'm always sweating. One of the hardest bits to clean on the watch was the strap and the small gaps in between the pieces.
To my surprise when I dropped the watch into the cleaning solution orange looking moss came growing out of the gaps and stuff. I should have taken some shots of the water, BEFORE putting the watch in. The light button had a growth which was darker shade of red close to black. I was surprised of where all the grit and dirt came from inside the gaps of the straps. Amazing.
Check out the video below also includes 10 seconds of time lapse photography right at the end.
Warning: If you plan to drown your watch please ensure that the seals are still working or else you may get liquid in your watch. I will not be held responsible if anything happens to it :P
