Start over. There shouldn't have been a clear coat applied to an exterior surface, especially a wood deck. I'm not aware of any clear product recommended for a deck/porch. Even when exterior doors are stained and clear coated, when they are exposed to the sun and rain, they will degrade and need maintenance every 1-2 years. A deck/porch is an difficult surface to coat, it is exposed to the sun at an extreme angle and rain/snow also lays on the surface.

Once you remove the clear product and the stain, I would apply an acrylic deck stain product. I use Pittsburgh Paints Sunproof Deck and Siding Finish. If you use a semi-transparent product expect 1.5 - 2 years before re-applying. Solid color 3-5 years. Even though they are acrylic/water soluable products it does not mean they are inferior. There has been tremendous strides in the past 10 years to make these products superior to many alkyd/oil based products.

Visit a paint store and they will steer you in the right direction.

Good Luck
