Can't focus

Telling us what camera you have might help.
I would check to see if the camera is in af mode first just as a general thing.

I've used toothpaste and a Q-tip to clean a cloudy & scratched viewfinder, but the focusing screen? Yes, that does sound scary.

Toothpaste has a mild abrasive in it and is water soluble. I have used it on the car for removing small scratches, but never have I tried it on the camera.

Depending on the camera the focusing screen can be replaced even if you did damage it. What camera was it and what possessed you to try this?

It's the minty fresh fumes that are causing your problems.

Toothpaste contains mild abrasives. You should avoid touching the surface of focusing screens with anything as the surface is very delicate and scratches very easily. Solvents should also be avoided. An abrasive will have changed the light transmission quality of the focus screen. There is nothing that can be done to restore the proper surface of the screen other than replacing it. AF in Liveview should still work.

I have looked everywhere for a replacement to a cannon xti focus screen and I haven't found a thing):
