Look like both sides need to be cleaned and hopefully that\'s not some fungus we are dealing here:
1) Use a fine needle to lightly push & peel off the lens signature front ring. Becareful at this step since you are going to reuse this ring later on.
2) There are 3 screws underneath the signature ring, the front elements will drop out after unscrew them.
2a) Skip steps 3 & 4 if front elements were packed in one piece
3) Soak the front elements piece by piece in warm soap water for 10 minutes then slowly clean them out with Q-tip
4) Repeat step 3 with fresh water
5) Use vacumn cleaner that\'s tied w/ starbucks medium straw one end to suck all the dust from the other haft of the lens (front & back)
6) Make sure all dried up then use Eclipe to clean all optical elements that you can reach. Treat this stage like cleaning any image sensor.
7) Reverse what you did
