Lethal Decking!

I would try external varnish and a dusting of course sand over it while it is still wet

You have this same compromise on boats. Really durable genuinely non-slip surfaces are ugly, expensive, and will take off the soles of your shoes (or feet!). On the other hand you settle for something not too slippy, take care, and keep it clean.

After I got rid of the slippy decking I had a stone slab patio laid. That got slippy too.
My neighbour used to buy some cleaning liquid from the Farmer's store that was used for milking parlours. He'd spray it onto the slabs with a garden sprayer, leave it to stand for a while, then brush it off with a stiff broom. Had to be done every year. Would probably work on decking too.

I'm not really surprised that someone would cut a criss cross pattern into steps with an angle grinder.......the " where there's a blame there's a claim" culture has a lot to answer for. Truly non-slip surfaces, particularly when wet, are nigh on impossible to find. I remember my husband painting the passarelle (gangplank) on our boat with a mix of epoxy and lots of gritty sand for the benefit of our cat. We used the handrails as well.....I really don't like decking. I always imagine rats and mice are hiding underneath.

Cleaning fluids generally = toxic to plants
Power hosing is the kindest to the environment surely?

But not just before a " big freeze"

Not many plants grow in a stone paved patio!

Yeah, we did have to contend with a rat in residence under the decking when we were doing the conversion of the cottage...

I was thinking of any run off?

[veggiechicken]

It wasn't applied in gallons, just a spray on the slabs that was left to dry and brushed.

Keeping it clean is the key. The trouble is (as is normally the case) you need to do it before it gets slippy.

Pressure wash in the autumn when it's due to be dry for a couple of days after and then re-treat with stain to firstly remove any mud and algae and then to seal the surface to prevent build up over winter... and then hose it off in the spring when the worst of the weather has passed.

We have a bridge over the stream at the bottom of our garden which has decking planks and it is treacherous right now as it stays humid down there all year and i don't have electricity or a hose point nearby to pressure wash it!
