Magnum 6 mask fogging problem

I recently purchased a Sherwood, Magnum 6 mask with the 6 windows. I have made 5 dives with it so far and have tried nearly everything to prevent it from fogging. Yet is STILL FOGS up! I also own a Sea Vision 2000 mask with the red tint and it doesn't fog much ever. What can I do about my Magnum 6? I was really excited about it when I bought it but now I am growing to hate the mask because of the intense fogging.

Here's what I've tried so far:

1. DEFOG by Sea Vision
2. SPIT by Jaws Products
3. Washing the mask with dishwashing detergent
4. Washing the mask with toothpaste
5. Baby shampoo as a defogging agent
