How can I improve/protect my 7-year-old Tornado Soccer foosball table? - bubble soccer

1) The basement of my new place is relatively dry. I have a dehumdifier you with the day, but since my wife the reason (why the show is off), and he lived there for months, I do not know how he enters the winter. My table is here, even if the winter cold?
2) The metal bars were "sticky" very well in recent years (beer, spilled greasy hands, etc..) What can I use to them nice and soft and stay that way? Everything I've used before, is there a generic box WD40, but the sweetness does not seem to take too long.
3) The table is in the carpet, concrete and wood floors with adjustable height of the net at the bottom of the legs are completely out of control at that time were. I tried the old baseball cards, coasters, journals, which also try to always, as the table level. Has anyone tips for me to achieve the perfect result? I use one of these bar "bull-judge" which can not perfect.
