I prop it against the nearest wall (with a towel over the top to protect the wall). Once I have the hatch out of the way, I climb down and extend it into the attic.
I only use that ladder inside. I have little giant clone for the outside. When it has been raining or snowing outside, it’s really hard to clean a ladder before taking it inside. I like the extend and climb because it fits behind my seat and stays clean.
I lost one of the rubber feet off my Telestesps once and was able to order a replacement pair. If cleaning does work and they are just worn then replace them.
