I don't know whether it needs cleaning or not, without seeing it. I
don't think mine is dirty at all after 26 years (??) but some of the
fins are bent together at the bottom.

The fins are in good shape (not bent), but about 30% of the surface area is
clogged with what appears to be something similar to dryer lint. Very
fibrous.
