It sure helps out the undercarriage of all the vehicles too! Especially big rigs! That brine does do as intended, however it is tough on autos, trucks, soils; water wells and water supplies. We get blasted with the stuff up here, and I'm not crunching the numbers concerning safety issues, but if your well goes to hell, hope you know someone at the water bottling plant.
By the way, all the ex-conn folks you sent us have created for their 'new found friends', "chemical free zones" so now we can slip-side away, as Simon and Garfunkel uses to sing about!
In case you have not noticed, Turkeys and deer really like the 'salted grasses' beside the roadways in the spring, too.
PS: The ABS systems on TT units and straight rigs are taking it hard with the new chemicals, and there will be NO CLUNKER Law for Freightliner. Navistar, Peterbuilt, Volvo and other manufactures to cash in on.
