Methanol drying error

I just realized I made a mistake while trying to dry my methanol. I thought I'd seen it mentioned that KOH can be used. Of course I'm stupid enough that I didn't first check!

So I poured my methanol into a bottle with some KOH in it. This was exothermic and some of the hydroxide dissolved.
After looking this up, I see I might have made some potassium methoxide.

Anyone have an idea as to whether my methanol can be salvaged?

Unfortunately I don't have any molecular sieves. And MgSO4 or NaSO4 are not appropriate.

You should be able to distill it. You might want to first add some magnesium sulfate to prevent glassware etching.
