Thank you to all who responded to my question about laundry detergentwhen I couldn't find Dynamo.
 Many people said Tide Free and so I called Proctor and Gamble They said that all their laundry products are GF but they can't be sure of the fragrances put into them.  To be absolutly certain, using the ones labeled "FREE" would be the best. ( Although 1 person said they got a rash from Tide)
Others used Gain with Bleach, Era, Dr. Bonner's Castile soap, Fab, Ajax, Cheer, and many used All(Free and Clear).
I also found Dynamo again being sold at the Walmart.
