A couple of weeks ago, after a few days of rain, I went out the spa room door to try to entice the cat to venture out. It was like stepping on black ice. The days of rain on the mold on the steps had turned it into a slime with a negative coefficient of friction. I managed to fall in a way that I didn’t hit any sharp edges. So I made up my mind that had to be addressed. I spent yesterday and today with bleach, a stiff brush, and some MOLDEX and some GOOP grit spray. What a difference. The first day I did not do the corner so you can see the difference clearly.
