Been trying to work out for weeks what was causing the weird little brown circular stains all over my daughter's clothes. Today we finally figured out it's dandelion sap, from picking the flowers from the lawn! Cannot for the life of me get them out - I've tried two different stain removers and neither made the slightest bit of difference. Ironically it seems to have happened to most of her "nicest" clothes so I'd love to get them out. Anyone had any luck with this??
