Sierra, Silverado, Avalanche, Yukon corroded brake lines

My neighbor who owns his own repair shops has been replacing brake and fuel lines on all types of vehicles all the time lately the main reason up here in the snow belt is the liquid deicer they use on the freeways now it has beet juice in it to help it stick to the road but it also sticks to the bottom of vehicles very well too He suggests hosing off the bottom of your vehicle often especially after they have salted and deiced the roads
