Q. I always used grease on my car’s battery cables, but my local mechanic tells me it isn’t a good idea. When my battery was serviced he used a sticky spray which he told me is now the recommended procedure. What is wrong with grease?
A. Grease is an acid and although aids in sealing the connections at the cables it can dissolve and cause its own share of problems. The battery sprays are designed for this and work well. I have personally had good luck with barbeque paint; it dries quickly and forms a good seal to prevent corrosion.
