I regularly wipe the dirt and grime off the rails that it rides on underneath. Nothing is usually needed but sometimes I will spray some dry silicone on them.
Another thing I do is run the slide in just enough for it to raise up on the inside floor, then stop it and crawl underneath and wipe a old cloth with some silicone spray in the trough the length of the slide, where the seal sits on the bottom. You will be shocked at the grime that builds up in that area. You can also raise the carpet on the inside and vacuum more grime out.
I also inspect the top material.
