Drops on my lens

When I try to have a split level photo, most of the times the photos are not clear due to the drops of the water on my lens. I tried to clean it in the same way I use for my mask without any results. Do you know any tip?Thanks.

I use baby shampoo on the port. I picked this up from reading other posts on wetpixel. From what I have read defog is not good for acrylic ports. The baby shampoo seems to do the trick

If it's a glass port you can use Rain-X. If it's acrylic, try baby shampoo.

Cheers
