Romisen lb-030!!! please help !!!

hello guys!!! i recently bought a romisen lb030 green laser (30 mW) from DX.
Yesterday i tried to clean its len by using one cotton bud with a bit of alcohol but i made it a bit worser!

Please tell me how to clean it perfectly.:undecided:

Help me:bowdown:

I suggest you microfiber cloth.

Take one of those that optics give for clean glass lenses, put it around the cotton swab, and gently pass on the lens ..... change the part that is in contact with the lens some times, til you get the lens completely clean.

And if there's no grease on the lens, just breath gently on the lens time by time, when you're cleaning it (making a little dew on it, i mean), can also help removing tracks.

At least, for me it always works
