Thanks to the wonderful people of Mumsnet Housekeeping boards I discovered these little wonders.
I have been using them in my washing machine to do a maintenance wash and down the sink to get rid of small blockages and freshen up.
What else can they be used for? Can you dilute them in a spray bottle (with Zoflora of course!) for example? And it says on the packet they can use them to get rid of limescale, does that mean you can put them down the loo and use them to clean the bathroom?
