I cannot sing the praises of the E-cloth enough. This E-cloth or any E-cloth for that matter. They are simply amazing.
Yes expensive, but it really is one of those investment decisions you make instead of opting for yet another £1.50 multi pack of sponges and scourers. The other day, I yanked out a pair of trousers, put them on and to my horror, some kind of dried on gunk lurked. I was late for an appointment. Tiny bit of water, E-cloth, 1 minute and gone. You can use these things for so many applications.
One other thing, if you really want to make the most of these, particularly if like me you have any allergies, or eczema or asthma, invest in a steam cleaner. No more harsh detergents and asides from a hoover, probably the only cleaning gadget you'll ever need. I have one and it's amazing. With the E-cloths in tow you'll never look back.
