I put ice melt in trouble spots like stairs and slopes. If we get some icy rain or slick conditions I put ice melt on all driveways and walkways I only do residence tho. I use a small hand spreader holds 5 pounds and a walk behind cheapy scotts broadcast for the bigger driveways holds 15 pounds I charge my customers 1$ per pound and they think its great I pay like 8cents per pound I Get a brand called near zero its sold at lowes for like 9 dollars for a 50 pound bag and at a wholesale place for about 7$ a bag if you buy a pallet which I don't cuz I use maybe 4 bags a year lol
