Mine looked just like yours. I used a citrus based varnish remover. When clean, it looked like a spotted pony. There were light and darker spots all over it. I used a Scotch Brite sanding pad and then used a good quality oil stain to bring the light color spots in line with the regular color. Looking back, a wood bleach would have made it all the same color and it would have perhaps taken the stain more evenly.
