We have some Treadmaster non-skid in our companionway
that is starting to get kind of slippery. It still has raised diamonds, so I got to believe it is still good. I tried taking a wire brush to it, but that only cleaned the dirt off, but did little for making it less slippery.
Does anyone know how I can resurrect this non-skid to make it less slippery? Is there a liquid I can put on it to rough it up? Or something else I can do? Any info would be helpful. Thanks.
