Review on Amlong Crystal Triangular Teaching Photography Science Education at Optics by Antonio Bacon

I received the prism and took it out of the box and the surface was blurry on all three sides. I rinsed with water and tried using a microfiber cloth to avoid scratching the surface, thinking it was food residue or fingerprints, but the fluffiness/stains didn't go away. There is also a small scratch on one side. Since I will be using it for photography I would like the prism not to have an annoying haze like this. Please see the attached pictures to see the defect on the three sides of the prism.
