well
Carb cleaner I'm not even going to bother trying to explain why its bad. Just don't use it on anything for your truck.
Chlorinated brake cleaner on the other hand. It will eat plastic, rubber and will corrode most metals. If thats not the least of your worries it contains Perchloroethylene Which has been proven to cause nervous system and liver + kidney damage just for starters.
It also contains Methylene Chloride which is carcinogenic, can cause cancer and is used in certain aspects to weld plastic together.
Non chlorinated brake cleaner came along, which removed most of the unhealthy stuff above only to replace it with more unhealthy stuff like the following.
Acetone - You guys should know this stuff. You probably used it to remove paint at one time or another, or stole your wife/girlfriends nail polish remover thinking you can unglue that wobbly pair of big joe's. Acetone while it is used to make plastic, will eat/weaken plastic and rubber if applied after its formation. It also causes liver damage.
Toluene/methylbenzene - This is a solvent for the most part, it will dissolve paints, glues, and rubber over time. Repeated exposure has been linked to brain damage.
Not all damage is caused instantly guys. Plastic, aluminum, and rubber exposed over a period of time to these chemicals will weaken their state. Either by microscopic pitting or actually removing moisture from nylon based products over time causing them to go brittle.
ALL these cleaners including the simple green / denatured alcohol / wd40 that I use will pull any grease/lube out of your bearings, so please take special care when spraying around them or make sure to lube them frequently.
This information is posted so people here can make an educated decision on what you want to use to clean your truck. I honestly don't care if you use a stick with monkey turd on it. People will use what works best for them. But please know what you are using.
