Playtex The Insulator Straw Cup Sport 9 oz Review

Playtex Insulator sports cup can keep a drink cold for hours. Its strong durability is a plus especially when you have a child who is a constant thrower. The straw stays put and the straw cover is a added plus to keep sanitary and clean on outings.

This cup is my son's favorite. We love the colors and the design. We found that after several months of use the one flaw that I found in cleaning this straw sippy cup is after pulling the straw out if you look in there you will find mold and black gunk that is impossible to get out. I  washed this cup by hand and by dishwasher and still can't seem to get that part clean. Soaking didn't even seem to get this clean. If anyone has any tips on cleaning this out I'd love to hear them.
