Slot car track gurus

Ok so since I’ve been stuck at home with Covid, decided to break out my old slot car track as something new and different for the kids to play with it. I got this back in 1998 for Christmas. Played with it barely at all cause mom hated me having it set up in the living room. We moved that following spring and it never made it back out of the box until yesterday.
It’s an old Tyco HO scale NASCAR version. Two cars, both are junk, tires crumbled, corroded from sitting in the attic all these years. So I’ve ordered new cars, one a 1964 Max wedge version hehe.

but my question is, is there a good way to check the track while I wait for those to come in?
