If you don't wash, you risk contaminating the product with whatever was on the petals.
But isn't all the idea of the distillation here is to evaporate
the hydrosol+water and condensed them back,while all the contamination is remaining with the petals solution
on the bottom of the big pot?
And if i will wash the petals before the refining,wouldn't the petals lose from their strength and i will get,since that,less fragrance hydrosol solution?
