Decking in the Winter

This is probably the only reason that has put me off of having done.
One of the only good solutions to stop it being so slippery is to attach chicken wire over the top to give you some grip. This is what a lot of big gardens do where the public walk, otherwise they would have loads of claims for slips etc...

Not ideal if it is right outside youre back door, but maybee something temporary over the winter months.

This is the drawback with decking, household salt is the best, remember to check where it drains off in flower beds.
The level of the decking can be set to drain off, also remember to keep the decking clean in the slits.

One solution I have never seen used on decking is to varnish it when it is dry and sprinkle washed sand over the wet varnish. This will result in a finish like sandpaper.
I know this works because it is used inside sailing dinghies made of wood to prevent slipping

i like your idea Andrew. i have a similar problem.
