Autoglym has been a staple in the detailing world for decades. Founded in 1965 in Letchworth Garden City, the British brand is celebrating its 60th anniversary in 2025, with its products now sold in over 45 countries. It’s also famously supplied the Royal Household - a royal warrant that’s as much a marketing flex as it is an endorsement of quality.

So when a box of their products landed at our office, we decided to put them to the test. The candidate? My little yellow Honda S660 - a kei-car that turns heads everywhere it goes, but was in desperate need of a deep clean. Dust, road grime, fingerprints, and streaky glass made it the perfect canvas.

And just to be clear: this isn’t a sponsored feature. Autoglym did send the products, but what follows are my honest impressions from using them on one of the filthiest cars I’ve owned in recent memory.

The Process: From Pre-Wash to Ceramic Finish

Pre-Wash with All Purpose Cleaner

The Honda arrived covered in a thick film of dust. Autoglym recommends their All Purpose Cleaner ($29.99/1L) for dirty lower panels, wheels, and door jambs.

The instructions suggest applying it dry, but given the state of the paintwork I opted for a wet application to avoid dragging dust across the surface.

Spray, agitate with a wash mitt, and already the yellow paint began to show through again. It lifted grime quickly and without fuss - a huge difference in minutes.

Ceramic Wash & Protect

Next step: the wash itself. Autoglym’s Ceramic Wash & Protect ($42.99/1L) pairs with a microfibre wash mitt to both clean and leave behind a thin ceramic layer for gloss and hydrophobic protection. Foam was thick enough, lubrication was good, and after rinsing the water-sheeting effect was obvious even before adding any toppers.

Fast Glass for the Windows

The glass was another story. Dust and streaks inside, grime outside. Autoglym’s Fast Glass ($19.99/500ml) is safe on tints and touchscreens, and the results were impressive: streak-free, no haze, and mirrors that actually looked crystal clear. It’s one of those small steps that instantly lifts the whole look of a car.

Interior Revival

Inside, the S660’s cabin was - frankly - a dusty mess. Autoglym’s Interior Shampoo ($23.99/500ml) handled the fabrics and plastics, lifting grime from the steering wheel and carpets without leaving residue. A follow-up with Vinyl & Rubber Care ($27.99/500ml) restored the dashboard plastics with a subtle sheen — thankfully not the greasy shine some products leave behind.

Rapid Ceramic Spray

To finish, I applied Rapid Ceramic Spray ($37.99/500ml). A mist on each panel, buffed off with a microfibre cloth, deepened the gloss noticeably. It also left behind a hydrophobic coating rated for up to three months of protection. For a kei-car with limited garage time, that’s a welcome shield.

Wheels and Tyres

While this test was focused on paint and interior, Autoglym’s kit also included Advanced All Wheel Cleaner and Instant Tyre Dressing. On wheels, the cleaner’s colour-changing formula breaks down brake dust, while the tyre dressing gives sidewalls a fresh satin finish. It’s a good reminder that “the outfit isn’t complete if the shoes are dirty,” as their own tips note.

Tips That Made the Difference

Autoglym stresses a few rules that I found genuinely useful:

• Cloth discipline matters. Keep separate cloths: green for interiors, red for exterior paint. It avoids cross-contamination and swirl marks.
• Work top to bottom. The dirtiest areas are at the bottom of the car - tackle them last to avoid dragging grit upwards.
• Don’t skip the glass. Clean glass changes how the whole car looks, inside and out. Fast Glass might be the unsung hero of their range.
• Protection pays off. Ceramic layers, even spray-on ones, reduce how dirty the car gets between washes, making the next detail easier.

Verdict

After a long afternoon with the Honda, the results spoke for themselves. The yellow paint popped, the glass was crystal clear, the interior felt fresh, and water beaded across the bonnet like it had just left a professional detailer.

Autoglym’s range isn’t the cheapest — products hover around the $20–$40 mark — but they deliver on ease of use and results. The standouts? Fast Glass for convenience, All Purpose Cleaner for versatility, and Rapid Ceramic Spray for its instant gloss.

This wasn’t a sponsored clean, just a filthy car and a box of products. And after using them, I get why Autoglym has the reputation it does. The S660 went from neglected city runabout to something resembling a mini supercar again — and that’s about the highest compliment I can pay.
