I buy these Tesco Value Sponge Pan Cleaners regularly with my weekly shopping. There are 5 sponge scourers in the pack and although they may not be as big as some other sponge scourers available on the market I find that they work equally as well and at this price I can throw them away daily or after cleaning something really mucky without worrying about feeling wasteful. Changing them so regularly means that there's no chance of harmful bacteria building up. I use them mostly for washing up, the scourer side gets dried on food off easily with a little scrub. But they are great for cleaning all sorts of surfaces around the house, I usually use the scouring side to clean with first and the sponge side to rinse with, then I use a soft cloth to polish the surface with afterwards, I think they're great for using on shower doors in particluar. At less than 3p each sponge (14p for the pack), I think the value for money is brilliant.
