Replying to How to Revive Shitty Bases on Skis

Ive done a pretty shitty job of maintaining the bases of my skis in good condition. So I am wondering if there is any way that I can revive them kinda? the bases look all white and scratchy and I have tried waxing them but that does not really help. I am still able to ski on them, but if I had the money, which I dont because I am in college, I would definitely buy new skis.

Is there any way that I can wax them to revive them a good amount or am I fucked till I can afford new skis?
