Fanks… FAFO.. I did, my firm conclusion is black ice is racist. Skied across porch, off end, managed to roll fall. Cat laughed at me.
De iced porch yesterday, still good. Last year I used salt. This mixture lasting longer than salt.
2 tsp dawn
2 tbs rubbing alcohol
1/2 gallon water
Shake well, put in spray bottle.
Melted ice great, after water disappeared I sprayed again.
Friend said it works best if you spray before porch gets wet and freezes.
Freezing rain now, should be snowing its 29°
