How to clean an ITF (BF600/LUNT50)
Check out a few images of a "rusted" ITF filter (BF600/LUNT50) that belongs to a Portuguese club member
It is very easy to clean it using several products (e.g. car polish)

I have heard that Coronado ITF filters cannot be cleaned but have to be replaced. True?

Thanks Mark & James
The ITF can be changed but you can clean it as well. The best option is to replace it with the Beloptik ITF replacement filter

Thanks Pedro. It seems I had read somewhere that the Coronado ITF couldn’t be cleaned. I’ll save the Beloptik link. Thank you.
