Buy a bag of soda crystals. For around £1 you can use them for all sorts of things, I recently mixed a couple of tablespoons of soda with just a dash of detergent to wash down tiles. Brilliant result, no need to rinse or wipe. They also make a great soak for baked on stuff in oven trays, dishes etc.
