    How would the amount of salt and chemicals in say 50ml or 100ml of dish liquid diluted in a bucket of water, scratch paintwork that is designed to be hard wearing and chemical resistant? Just asking!

    However, for the price, I'd just buy the 'correct' stuff!

    Just have a look at the paintwork on any car that has been constantly brushed and sponge washed (a bright sunlight day for best results) and you will see the swirl marks....as we tend to follow the circular arc of our arm swing.... salt is an abrasive and over time these micro scratches gradually cover the paintwork and dull the shine.

    I think the salt is completely dissolved, not in crystal form, so scratching would usually be from dragging dirt/grit over the panel when washing.
