Add a couple drops of any household detergent (Mr Clean, Top Job, etc) and it will be.
By the way, CLR is basically acetic acid (vinegar) with the odor removed. Vinegar is much cheaper and does the same thing if given enough time or mixed with baking soda for a cleaner/de-odorizer.
Stannous is right about CLR. It also contains chemicals that can damage surfaces and your health ( http://www.chesterscleanhouse.com/2 ... eaner-uses-dangers-alternatives.html and http://www.hescoinc.com/Msds/comcl4.pdf ). After reading that I use vinegar instead.
