Great Stuff works well 

This works better than Calgon and you only use it once per month. I live in Swindon and the water is very very hard

This product is good and does what it says no mess no bother.

I’ve used it for my new machine and the one before that and it does very good job.

Good value for money!

The third time I've bought this product.
Excellent degreasing and cleaning capacity.
