No hotter than 150 degrees I believe. Don't worry about covering the holes too much, but some people use silly putty I've heard. Any tape in holes should come out due to the water so expect to replace it. Adding a splash of dish detergent will help lift the oil out of the ball as well.
Cat litter has been rumored to work, as well as hair dryers on low heat and sitting them in the sun. Dishwashers are used on occasion as well, but you have to be sure they don't preheat the water to too high of a temperature...
