white residue on door

Help! We have a custom mahogany-eucalyptus (?) front door. Gets heavy sun. It was stained a minwax cherry, but the sun has badly bleached it. My husband steel-wooled and sanded the door, restained it with the same stain, but after a few days a white residue appeared in places. After a few weeks, he redid the whole process, but the residue has come back and the door looks pretty awful. We are at a loss as to what to do now. Can anybody help?There has never been anything other that this particular minwax finish on the door. We also had the same problem on a different door. any help would be appreciated. :(

Stain is not a complete finish. It must be top coated.

What stain are you using? Steelwool is not an effective way of removing old stain and or finish.

A chemical stripper is the best way to remove old finish.

Use a NON poly varnish from a boat supply house or a marina. I may cost $45 or more per quart, worth every penny. Poly is easily damaged by UV.

Finishing is an 'Art & a Science'. Actually, it is a process. You must understand the properties and tendencies of the finish you are using. You must know the proper steps and techniques. Then, you must execute them properly.

To add to Scott's reply. Other than the Minwax Polyshades tinted poly, Minwax stains are intended to be applied to virgin wood or wood that has had any finish totally removed using a chemical paint remover. Use a paint remover containing methylene chloride for the best results.

Second, the stain should be applied and let set for 15-20 minutes and then all the excess wiped off. After the stain has dried for 24 hours or more, you can clear coat. As Scott suggested, a clear real marine non-poly varnish will give you the best and longest lasting durability. Go to a marine supply store and look for brands like Wolsey, Interlux, Pettit or, best of all, Epifanes. Carefully follow the directtions on the label.
