A friend of mine has started to use this and her car looks great, (this is a spray on cleaner-no water required) you then simply wipe it off,with a micro fibre cloth. It cleans all sorts of dirt, salt etc .
There are several types around, one is regularly featured on a well known shopping channel.
Has anyone else tried this and does it really work long term or cause any damage.
Thankyou for your comments.
