Sour Power is our gloss-enhancing shampoo, designed to leave behind a very thin carnauba film after washing (unlike Born to be Mild, which is designed purely to clean, and leave nothing behind).
However, as well as adding a bit of gloss to paintwork and fortifying the wax underneath, it still contains an array of powerful cleaning and foaming agents, ensuring an effective, highly-lubricated wash. Don't take our word for it - you can feel how slick it is between your fingers.
What else? Well, being pH-neutral means it's kind to underlying waxes and sealants - so it won't strip them off and actually increases their inherent protection thanks to the wax residue left behind.
It's also super-concentrated (about 3x standard high street shampoo strength), so you can dilute it with water 1:600 and it'll still work a treat.
Please note that because of the small amount of wax content we'd recommend that Sour Power is NOT used for washing the windscreen, unless it the screen is cleaned afterwards to remove any wax residue (to prevent any potential visibility issues in the rain when you use your wipers).
