Wash time

Thought it was a good day to give the aged dogs basket bedding a wash - didn't realise it had been such a long time since last washed and changed. The water turned an instant brown - even after x2 hand washes, 1 washing machine wash , 2 rinse cycles and 1 final long rinse - the water was still coming out brown - good drying day - the dog was quite suspicious getting into a clean basket
