slippery scissor stairs

I don't have a rear awning. I did think of just throwing a tarp over the stairs and then removing it when I needed to use them. I do shovel prior to walking down or up the stairs. Most of the time a wisk broom works. It's when it slushy or freezes after a rain that it is bad. At least I have learned to test the stairs prior to putting my weight on it!

I hope I can adequately describe what we did to our 5er steps:

I had a 2' x 6'(+/-) strip of astroturf, that I clipped to the top step with some small spring clips attached at the back. I draped it down the steps, then used a few pieces of thin threaded rod placed at the inside corner of each step (it kept the carpet from shifting). The rod was wider than the steps, so "locked" behind the edges of the steps. And clamped the bottom of the carpet to the bottom step. Was nice and secure, non-slip, and for my dogs, gave a "solid" appearance to the steps so they were less spooky about climbing them.

If the carpet got muddy or snowy, unclipping it and shaking it out was easy.

Growing up in 4-seasons I remember that nothing beats in fighting the snow than getting up at 5 AM and get a shovel
I had only single snow supersize camping in Sierra late in season, so it is not real experience with snow, but I do have rear awning over rear steps.
I wonder what set up you have?
From what I remember from my young years - salt is not good solution to anything. It helps in the moment, but side effects are devastating.

I already have the gripping surface on the steps and have added more of the non skid tape to the front of the step. The towels only work for so long. As soon as it has some snow/slush on it, it gets slippery. I like the idea of the heat tape. If I run it down one side would it heat the whole tread or would I need to run it across the tread. Would a heat tape be hot enough to burn a dogs paw?

Maybe toss some salt on 'em? That would melt the snow off. Start with salt before the snow and freeze even begins and they should stay clear.

I put Astroturf on one of my steps -- it cleans off the ice, snow, and dirt. I used long cable ties to fasten it on, but a good spray adhesive would work, too.

Strips of non-skid tape might help but I don't think short of a heat strip that anything is going to work once the rain starts freezing on the steps. Even carpet will eventually become a block of ice as it holds the water in place.

Wrap around carpets or painting the tread with bed liner would work. We extend our awning to keep our steps dry and find the GlowSteps have enough extrusion that they need nothing else.

We just replaced our old wrap-around carpets with new ones that are made to fit the stairs and have a velcro strip to hold them into place once wrapped around.

How about pipe heat cord?
