The stains used on our bed frames varies, depending on the color selected. Rustic raw does not use a stain, and is the most "pure" of the available options (and our personal favorite, shown below).
Other color options use the following color stains:
Natural: Brown by J.E. Moser's® (water soluble)
Expresso: J.E. Moser's® Black and Brown 20 Sheen Aniline Dye Stain (water soluble)
White: Old-Fashioned Milk Paint by J.E. Moser's® (water soluble)
Grey: Old-Fashioned Milk Paint and Espresso by J.E. Moser's® (water soluble)
