Auto Express have published their impressions of ten pressure washer shampoos. 'Even if you're not looking for the easy life, a pressure washer and specialist shampoo can help protect your paint - the less grime you have to shift from the car with a sponge or mitt, the less likely you are to scratch the finish. These shampoos were once the preserve of pressure washer makers, but there's now a big choice as car care producers and specialist detailers offer their own versions. They usually come in big five-litre packs, and represent better value than just filling the washer reservoir with standard car shampoo.'
