DH and I treated ourselves to new sheets (naice ones) from JL. High thread count and cost too much.
Both knackered when we got in yesterday so just chucked them on and didn't do the normal prewash.
Both admitted this morning the sheets were stiff and scratchy.
I've read up that if you just do the normal wash, the fabric softener locks in the chemicals and to wash them first with baking soda and vinegar 
Mostly American websites and never heard of this! So before I strip the bed and make my move...any suggestions?
