I love Fels Naptha!  Want to get blueberries out of that favorite shirt?  Worried about the mystery spill on the carpet?  Or wondering how to best remove any visible reminders of an explosive diaper?  For under $2 a bar of this bleach-free, detergent-free soap gets out all of the above and more!  And a little will go a long way; I received one bar as part of a gift at a baby shower a year ago, since my daughter came along it's been used about everyday and I've still got some left over.  It's saved our sheets, carpet, clothes, etc a million times over!  You can find Fels Naptha at the link or at retailers like Walmart.
