Trailer Rollers

[amateurfishing]

Is there any maintenance on trailer rollers? Re greasing or anything?

Also, is it necessary or essential to clean/wax aluminum boat hull?

I did not do anything last year, wondering if its necessary this year

I wash the aluminum hull about every other week with a pressure washing machine and more often if i'm going to different lakes. Partially to keep water marks off the hull but more to do my part and help stop the spread invasive species.

not sure about the rollers.. But if they aren't rolling, a little grease wouldn't hurt anything
