my MW just scooped it out with a sieve and put it in a bucket. DH got rid of it the next day when EVERYTHING (apart from pool) was wrapped up and taken to the tip. So I didn't even see it. I was only aware of one time she scooped some out. They don't talk about it, it's just dealt with.

It's beyond your control anyway. Imagin you had a post-pack tube, then stickytaped a tube of toothpaste in it. And then tried to pass a cricket-ball through the tube. Nothing you can do, toothpaste has to squeeze out to let the ball (head) through!
