isn't it posible to push the lens inside the moduler or smthing? I just get an ear-cleaning cotton and so carefully i rotate it while touching the lens
no don't use a cotton swab or microfiber the only safe way to clean a laser lens is with a professional lens cleaning kit. you can pick one up probably at a pharmacy store for close to 15-20 bucks. they ensure nothing goes wrong because cotton can actually leave hairline scratches and microfiber may leave marks. buy a lens cleaning kit. and do it right. that is what dragon lasers and wicked lasers say about all lens cleaning conflicts
hope that helped.
good luck
