You can control the temperature better by adding more or less hot water as needed. This isn't real cheesecloth, and it won't be useful for draining anything. Cheesecloth is a much thicker, muslin type 100 percent cotton. It can be washed in hot soapy water with bleach and be used over and over again. When held up, you could almost see through it, but not clearly.
Old pillowcases work great for draining cheese.
I cut open the seams and wash them in hot soapy bleach water. They make a nice square yard of cloth and can reused for years until they actually wear out. To hang the cheese, we use old shoelaces which we also bleach and use over and over. Tie a big knot in each end of the lace before using. This will keep the laces from sliding out while the cheese hangs.
