Fungus on my lenses

[MichaVandiver88]

Hi, Long time Canon Pro but first time having to deal with fungus growth on my lenses. I recently bought a B&B in Costa Rica and so I am part time in Costa Rica and the States. I have a dry room where I have kept my lenses (inside a Pelican Case) while in Costa Rica and the humidity was so bad that my lenses now have fungus. Is this something that Canon will fix / can clean or am I just screwed? Hasn't affected the quality of the images... just yet but wanted to send them all in for a good cleaning anyway. Not cheap, I am sure but wanted to ask if anyone has had issues with this themselves. As a nature photographer traveling the world, I am sure I am not the only one.  Thanks so much for your help!

Hi Ernie,

Happy New Year to you.  Really not sure why.  The beach probably didn't have any correlation.  It was just the last place I visited with the lens.  Young kid, first year of college.  I must have given it the right conditions or wrong ones.  ☹️

I think Ricky was suggesting a more specific cabinet solution vs room based humidifier.  I think he's suggesting a dry cabinet. 

For portable solution to use within your pelican cases, you can use something like this (you can reuse by microwave)
