What is your lens cleaning solution of choice?

Store bought, commercial products?

Home made?

Best source for purchase?

I use the lens cleaning spray and ultra fine microfibre clothes from Visible Dust: www.visibledust.com (http://www.visibledust.com)

Available from Amazon and lots of other photo/video places. The cleaning spray goes on the cloth, not directly on the lens! And a puffer to blow off any dust/grit first.

It's not the cheapest, but it seems to work for me.

The night before a shoot I use cloth and lens cleaning solution.

On the shoot itself I carry a lens pen and use that if I'm worried about picking up any dirt on the lens. Because it's quick and convenient.

Another vote for a Lens Pen.

A little breath and a microfiber cloth.

I use a microfiber cloth and spray available from Quality Accessories.

Quality Accessories (http://qualityaccessories.com/)

They worked so well that I purchased more than a hundred of them as custom-labeled lens cleaning kits to give as gifts to guests on our show.

I always use compressed air before i use the lens cloth. It blows off anything that may scratch the coating on the lens.
