Some times young hams are just having too much fun to stop running & go for a pee in the right place! Dwarf hams will often continue to pee in the wheel forever but syrians are more likely to grow out of it, they can also do it to mark it as their own so don't clean it too often, the more you clean the more they pee!
I generally give mine a wipe down with a damp paper towel every couple of days, no cleaners or disinfectant then clean it with a fragrance free pet safe disinfectant about once a week.
