I was thrilled to receive my pillow for my screened in porch from this manufacturer a few months ago. However though being labeled indooroutdoor I am very disappointed to see possible mold spots have developed. Can this pillow go in the washing machine It’s tag does not say washable. I feel though I should register a complaint as I don’t think I will display this new pillow in its present shape. All my other porch pillows have done fine. Please let me know what I should do about this...
