For something that smells as good as they do, I must say I'm surprised at how effective the stain removers are. They leave very little shadow. I plan to really put them to the test on some quite old stains that nothing - not even time - has managed to fade. I find they work best with a little time to work - a spray as I'm sorting, not just before they go in the machine, seems more effective. The fabric sprays are great too - just the thing for when clothes aren't really dirty, but an airing just isn't enough. I'm old enough now to avoid smokey places, but I'm tempted to find one just to test the spray!
