Cleaning Rear Lens; What to use?

I have recently purchased a used lens, and I see a spot on the rear lens that I can't seem to blow off with my rocket. So I'm not sure what type of cleaner to use on it. Is the rear lens a different construction from the front? I don't want to scratch the lens or coating.
Any suggestions would be appreciated. Thanks.

After blowing I use a lens pen, if there is a spot I use a lens cleaning kit tissue and the lens cleaning solution to wipe away the spot.

You can also try a lens pen.

Yup......love my Lens Pen. Don't leave home without it. Gently brush thelens, then use the lens cleaning portion of the pen to polish the lens. Instructions come with the package.

The thing I don't like about the Nikon Lens Pen is the missing cap for the brush end.

What I do is.....before I use the brush, I flick it with the tip of my finger to dislodge anything that might be on there.....and I do the same after I use it, just to make sure. I don't need another cap to worry about and lose. Also, I store the pen in my camera bag so it doesn't get dirty when not in use.

As Capt. Rex Kramer would say, "You don't know where that finger's been." I usually blow on it, but what's the difference between boogers and spit to a lens?

You're probably right about the cap and I keep mine in the bag as well.

LOL.....well yeah, ya gotta have a clean finger, that's for sure. I also blow on the brush, too.
