New sight glass is your best option and is about £20. Part number was  4h7-15361-00, but  it has been superseded by part number 2h7-15361-00.Don't know of any effective way of cleaning it or anyway of removing it with damaging it.

In the dim and distant past, I've used cotton buds on some bikes to clean the glass.
[/quote]As have I, Scotty, but the issue with the FZS600 is trying to get at it, you might be able to get at it with the sump off, which means taking the exhaust off. For a €20 it wouldn't be worth the trouble
