I recently acquired some 2nd hand Keester Kovers and they were stuck in my mailbox all day in searing 39C degree heat. When I opened them there was a bit of a urine smell and so far I haven't been able to shift it.
I have washed several times and done strip washes and sunned them heaps and I can still smell it. Granted it isn't really strong and you have to stick your nose right on the cover to smell it but I'm fussy
What are the rules with
fleece and what could I add in perhaps to remove the odour?
TIA
