Angelwax is a Scottish manufacturer with a strong following for its concentrated chemicals, and Bilberry is the product that made the name: a superior wheel cleaner sold as a concentrate that dilutes a long way, which is why it appears in so many professional setups. The wider range covers Superior Automotive Shampoo, Fastfoam snow foam, Cleanliness citrus pre-wash, Vision glass cleaner, H2GO rain repellent, Heaven For Leather and the Enigma ceramic line.

Bilberry is sold as a concentrate specifically so you can dial the strength to the job, using it stronger on neglected wheels and much weaker for regular maintenance cleaning. Always follow the dilution on the bottle for your version, work on cool dry wheels, and never let it dry on the surface. Because it is acid free in normal use it suits most painted and coated wheel finishes, which is the main reason it became a default choice.

Enigma AIO is an all-in-one ceramic compound, so it corrects light defects and leaves ceramic protection in the same pass, which makes it useful on a car that needs tidying rather than full correction. Enigma QED is a ceramic quick detailer for maintenance: it goes on after a wash, adds gloss and water behaviour, and takes minutes. AIO is the once-a-year job, QED is the one you use most weekends.

Yes, H2GO is a glass rain repellent and the windscreen is exactly where it earns its place, because above roughly 40mph the water beads and clears without wipers. Preparation is what decides how long it lasts: clean the glass properly first, ideally with a glass polish to remove bonded contamination and old repellent, then apply to dry glass and buff off any residue thoroughly or you will see smearing at night.
