I have heard that you should not apply spray silicone to CV boots even thought it does preserve the rubber. Is this so?
Yes! Also, avoid using solvents, engine degreaser or brake cleaner on CV joint boots. Keep them clean with mild soap and water. While spray silicone is good to help preserve the rubber parts of your vehicle, but it shouldn’t be used on CV joints. It isn’t a good idea to put silicone, vinyl protectant (ArmorAll), or other type of petroleum product on CV boots. A problem is created when the protective coating attracts dirt which then sticks to the surface of the CV boot. Once the dirt clings to the CV joint, it acts like sandpaper on the CV joint bellows where the boot compresses. As the CV joint flexes, the abrasive action of the sand weakens the boot and eventually causes it to tear.
