LOOL! I just found out that I accidently washed my R4 when it was in my jeans!!!! The funny part was.... that it still works! xD! It smells nice now I'll try not to wash it again next time... It might not work!
Many electronics will survive water as long as they are not powered up when they get wet, and are not powered up until they are dry. It's the water + power that ruins them.
