new formulations much less corrosive than any salt subtance
new formulations avail with low phosphorus - the main cause of runoff polution to waterways (result of a NY EPA report)
i ordered the bobcat 75gallon sprayer and the 10ft boom (much cheaper) off the 50 gallon sprayer. will fabricat a custom hitch attachment. bobcat authorizes use of de-icers in the sprayer. only question is: will i need to use any salt also? the main selling point of de-icers is that when mixed with salt they reduce the amount of salt needed by more than the cost of the de-icer, they lower the temperature of effectiveness of the salt, and they help the salt bind to the road. the counties here are constantly salting - all winter long - you can see the liquid de-icer tanks on the backs of the trucks. will use the sprayer in the summer also.
hopefully the deicer will be all i need to get rid of the ice with the broom. i have had very good luck with my broom so far this winter.
