I've been trying to remove the black rain funnel from the base of my Davis VP
to give the innards a bit of a clean but I've had no success. The funnel is
stuck tight to the base. Has anyone found a solution to this? As it's all
plastic, the amount of brute force that can be used is limited.

It's still peeing down here - another 3 mm since 09z

I've rarely known them to get completely stuck, although certainly
ones that have not been removed for years perhaps can sometimes be
stubborn. But in the end, with persistence, you can usually move them.

The key is to ensure that the ISS is still firmly secured to its
mounting point so that all the torque you're applying to the cover
does have a firm base to act against. It can be pretty tricky trying
to remove the rain gauge cover from an otherwise unmounted ISS.

But then it's 'just' a matter of applying enough torque to the cover,
eg with one palm on each side of the cover, trying different positions
around the cover if necessary. Sometimes if you look closely you might
be able to see which of the tab positions might appear the most
unyielding and then putting some extra downward pressure around that
point can help. With a really stubborn one then tapping the tabs (in
the right direction!) with eg a slim piece of kindling (ie a slightly
yielding bar/rod) and a rubber hammer might do the trick.

According to the manual it's just a matter of twisting it anti-clockwise. I
guess the problem is grasping the base firmly enough. One of those jobs for
four hands ;-) unless you're able to grip the base between your knees. As
mine is up a pole (like me sometimes) I restrict my cleaning to fishing any
bits of vegetation out of the funnel, cleaning the guard, and pouring
through it a jamjar of water to which one drop of detergent has been added -
first disconnecting the ISS from the Pro2, of course. Seems to work for me.

John,

Thanks. The ISS is mounted on a pole that can rotate so I suppose the first
thing to do is to secure the pole! The installation is still a bit "temporary".
I put it up the day after we arrived here and SWMBO has kept me busy with other
tasks since then :-(
