If that isn't why people aren't getting it all out, then what is keeping them from mostly emptying the tanks? There are thread post upon thread post of people saying they didn't get the full amount out.

You aren't able to change the temperature of the foam in the tanks with hot water or any short term heating. It takes days for the heat to reach the inside. The reason they aren't getting it all out is because they aren't heating it long enough and they aren't shaking it enough. I've never had a problem.
