Unhappy Problems with poly on stair treads

We used minwax stain and minwax poly on our oak stair treads. When I put the poly on the treads, it turned white, kind of looked like it was eating the stain. The more the poly dried the worse it got. We steel wooled and sanded to remove this white, restained and poly with new poly and different types and the problem is back. Can anyone help.

Polyurethane turned milky

When polyurethane turns milky it can be because of too humid conditions. Most often it is because the coating was applied too thick. The surface will quickly dry and the moisture in the polyurethane gets trapped beneath, resulting in a white, cloudy, or milky appearance. This tends to disappear after several days. If it does not, your only option is to resand and refinish under less humid conditions and to apply thinner coats. Multiple thin coats are best. You can go to www.minwax.com for helpful info and a discussion forum.
