Yes you can use toothpaste on the cart contacts. But it's best to take the cart apart, otherwise you'll get toothpaste inside the cart.
"First I use straight toothpaste by rubbing it in with my fingers until the toothpaste turns dark. Then I wet the toothbrush and start brushing away at it. After I feel it has been cleaned off well I rinse the contacts off and brush until the suds go away. Finally I polish it off with a cotton towel. You'd be amazed how clean it gets. And toothpaste is always around and cheap."
Just make sure everything is nice and dry when you are done, I use a hair dryer sometimes if I accidently got some of the chips wet.
I guess one of these days I'll post a video of a before cleaning - during cleaning - and after cleaning - problem is: All of my carts have been cleaned already!
I don't know how it compares to Brasso personally. I have not use Brasso not even once in my entire life, but I know it's THE best tarnish remover. I just don't know - are the contacts Brass?
