Sour Power is Dodo Juice's Gloss-Enhancing Shampoo with added premium carnauba wax to enhance gloss and add protection during the wash process. The performance above and beyond normal 'wash and wax' car washes has helped it to achieve an AutoEXPRESS 4 stars commended rating. pH neutral in recipe terms, this shampoo won't strip wax or sealant already applied to your car and is actually a great way to maintain an existing wax coating or rejuvenate one that is starting to fail... why simply maintain the existing coating when you can keep topping it up every time you wash?! It is also highly concentrated - about three times as strong as normal high street shampoos at 1:600 with water - and it foams and lubes exceptionally well, helping dirt and grime slip away from the vehicle's surface. The final benefit is a small one, but you'll appreciate it every time you wash the car - the fragrance is delicious, smelling of fresh apples. Various sizes are available, from 250ml to 1 litre. This 500ml size is a great size - large enough to be economical, and not so expensive as to be a big risk if trying it for the first time. Give it a go... especially if you've never tried one of Dodo Juice's detailer grade car shampoos...
