First, I apologize if this seems a bit off topic but since I can't find a StackExchange site where this fits, I imagine experienced gardeners would probably know how to solve this problem. So, I figured I'd ask here and take a chance.
This past Easter I bought my wife some flowers which contained Easter lilies. After the lilies bloomed, pollen fell onto a enamel-painted, white charger that the vase was sitting on.
When my wife went to clean off the pollen, and wash the charger, the pollen stained the charger and she cannot get the pollen off.
Are there any old, tried-and-true tricks that we can use to get the pollen stain off of a hard, painted surface?
