What's the best product for cleaning rifles and handguns and what is the best lubricant?

"Liberal Tears".  Google it.  It's a real gun care product that works great.

I have been using Parker Hale for 45 years so thats what I would recommend

I have been using Hoppes products since the mid 60s. Some new brands I am looking at.

Semen is pretty good for lubricating ur gun

Water with soap..... do you need more?

Hands down the best thing for carbon is Easy Off oven cleaner, as long as you keep it away from bare aluminum or plastic. I have noticed that here is a bias on this forum against  using anything not specifically made for guns.

That depends, a lot of people use Rem Oil; however, there are definitely better lubricants. I use FP-10 for most of my guns, but I'll occasionally use Rem Oil if I don't have FP-10 available.

I use Hoppe's No. 9 for cleaning and Rem Oil for lubing. I've been using both for decades and see no reason to switch as both work well.
