Our household has subscribed to Choice magazine (published by the Australian Consumers' Association) for over twenty years. The subscription has paid for itself many times over as the Choice team test and review all sorts of stuff: appliances, technology, food, cleaning products, service providers ... and we regularly consult back issues of the magazine when faced with a purchasing decision. Our washing machine, fridge, iron, vacuum cleaner and mobile phones were all selected based on Choice's advice. No regrets!
So, when a piping hot bowl of turmeric-packed curry and rice recently flew (seemingly in slow motion) through the air and upended on our light grey carpet (whoops) we consulted Choice for advice on carpet cleaners. They tested 26 different substances about two years ago and we were surprised and delighted to learn that a home recipe had outclassed all the commercial products! We tried it and it worked well. Here's the recipe (I'm going out on a limb and assuming that 'home recipes' aren't copyright):
2 tablespoons dish washing liquid [Choice suggested Fairy Platinum Lemon, as it had scored highly in other tests]
3 tablespoons white vinegar
0.25 cup water
Work the combined mixture into the stain, being careful not to over-wet the carpet. Blot it dry with a clean towel.
Thank you Choice! Excellent advice, as usual.
