Chocolatecatty, Oh gosh definately no offence taken hun.

I didn't think about the teething, Shelby is currently cutting a tooth so maybe that is causing a bit more of an acidic smell. I have asked DP to put me up a make shift line for me undercover to see if a bit of breeze helps.

Liz, I am a bit confused with the extra rinse to get rid of the washing powder? Could residual powder cause the urine smell to stick? I usually wash them in a hot rinse first (no powder) then a normal wash with half strength powder. I have never had a problem with the flat cloth smelling as they have always been soaked.
