If at all possible I would pull the wheels to get at all the corrosion. I broke an axle the last time I did that. C. W. properly admonished me that I should have soaked it in penetrating oil for a day or two. Instead I was in an all fire of a hurry. So take the education, Sunrise, without paying the tuition.
I doubt that I suggested soaking in oil.
If necessary, put some penetrating oil like liquid wrench on the hub of the wheel and let it soak in.
Break free is another good product, but as far as I know, it is only available as an aerosol. There are plenty of others.
