How to remove Thompson's water sealer from deck?

Last Thursday, I had Thompson's Water Sealer put on my side deck. What a mistake. It is a real mess. What can I do? I won't let them put anymore on the other decks until this is removed.

  The water sealer , which is Natural Cedar, is very streaky and ran down the side of the deck. I really do no like it. I have heard that water and ammonia will remove the sealer. Have you used that to remove sealer? I so that reply from someone here.

You may now have to apply a solution that removes oil. After application use a power washer to get the worst of it off. Time will take care of the rest. If I were you I would look for a phone number on the can and call the company for advice.
