Residue on my cups.

So, lately as I said in previous posts I tried Johnson's head-to-toe baby wash on my cup to clean it, bad idea. Simply because after I washed it to left it feeling soft but in a greasy way. I'm not sure if baby shampoo causes build up or residue but I boiled my cup last night in some baking soda and it seemed to get off the residue from the baby wash. From now on I'm only gonna use the diva wash and baking powder. But this Saturday I'm gonna buy more diva wash.
