Hanna Andersson rainbow striped bodysuit size 3T 90cm

Hanna Andersson bodysuit with snaps there are some very faint stains/discoloration near neck area see pics(it's barely noticeable but I tried my best to capture it in photos). we use only natural detergent and wash cold so I haven't attempted a stain release of any sort on this bodysuit. ask questions if you have any and bundle to save!
