I realize that this question might pertain to any type of firearm; I chose the 'handgun' section at random.

As a new gun owner, I've noticed there are any number of gun cleaners and lubricants out there on the market. When it comes to the care anf feeding of firearms, I'd like to make sure I don't use something that may cause damage or buildup or attract dirt. I've already learned some terrific information as far as Windex/water and ammonia from people on this forum.

I've also noticed the Great WD-40 Debate. This led me to wonder if there are products I should be wary of, or hard-to-find items? I've noticed some people are using synthetic motor oil; does this do the same job as gun oil?

Are the gun cleaning kits and gun lubricants that I see in the stores worth it, or is there something the more experienced people can share?

Please weigh in with your opinion: what do you use to clean and lubricate your firearms with? Does it matter if it's a handgun or a rifle or shotgun?
