About a month and a half ago i got raindrops on the lens of my PowerShot SX740 HS. They left a mark after they dried. I tried cleaning it off with a microfiber cloth. That didn't work. I also used a blower to get dust off before i used the cloth. I then applied some Bower lens cleaning liquid to the microfiber cloth. That did the trick. I know that one should not use glasses cleaning solution on camera lenses. I'm wondering if this applies to the lens of the PowerShot SX740 HS, because i have applied glasses cleaning solution that contains Isopropanol on the same cloth I used for the camera lens. Although i did not use it to clean the camera lens. I'm wondering if this would damage the lens,
