DSLR Viewfinder Cleaning Question

[bbg404]

Morning all.

After an amazing trip to the Farne Islands I thought I'd best sit and clean my kit as I was attacked by Terns and had a trophy land on my lens

Anyway I noticed the external Viewfinder glass is disgusting possibly just sea spray due to hanging out the boat photographing Dolphins on the way back!

I've got 2 Lenspens but it's a Lens or Filter pen and they don't seem to fit in the view finder and I've noticed Lenspen make a Micropen but they don't seem to be for sale in many places so I'm wondering if there actually any good!

Thanks

good quality cotton buds ,and lens cleaning fluid .boots are probably the best ,the cheap ones tend to leave micro hairs/fibres behind

I've got one of the micro lens pens. I use it for viewfinder glass and sensor. When it wears out I'll get another.

I use cotton buds,but I have got one of those micro pens,it came in a set of 3 different sizes
