Mary,
This is just a thought as I've not had the problem myself.
How about laying down some galvanised chain wire fencing
over the slimey ramp.

The high ridges in the wire mesh should prevent it from being slippery even when covered in slime.
It may need replacing from time to time but also may prevent serious injury.
Just a thought.

Regards,
Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
