Alright, just a quick question (or two, or three

). After finally getting both the wheels off and inventing new curse words, I noticed the speedo attachment on the front wheel looks like crap! I have a terrible picture here, as my phone is bad at being a camera:
Wondering what to clean it out with?
Also, the axles I am assuming are dry axles. What should I clean those with? If they are not dry axles, what should I lube them with?
I bought some Moly lube for the chain tensioners, as described in the desmo times book. I used to use simple green to clean everything on my old bike, as that was highly recommended, so I picked some of that stuff up. Also have Dupont Teflon multi-use for chain-lubing.
Also, anything else I should look at while the front and back wheels are off?
Thanks guys!
