Hi Steve,
There's that many poles out there at the moment it's hard to be able to have an opinion on them all but Maver, for their sins, do make good poles
As for keeping your pole clean, best thing I use is a can of Pledge, furniture polish
Every now and then take the pole into the shower and give it a good hose down. Undo the shower head and flush the sections through with warm water and then let it all dry - again the shower cubicle is a good place for this but it does help if you take your pole apart first as the missus generally doesn't like 13m of pole in the shower [8D]
Once it's dry, get a cloth duster and spray some polish onto it and then wipe the pole all over
Pledge is good for cleaning the pole plus it leaves a polished finish which helps repel water and therefore helps to keep the pole clean in use
It always helps to have a small towel, or beer cloth, in your tackle box and then if it does rain or you get the pole muddy you can wipe it off before putting it away. This is a lot easier than getting it back out again after every trip or finding it all manky and sticky because you didn't clean it between trips [
