2. RECOMMENDED – Simoniz Liquid Diamond polish and wax

Price: £5.39

Buy from: Amazon

Min price per litre: £12.53

The Simoniz Liquid Diamond polish is great value for a generally excellent all-round polish. It doesn’t match some others when it comes to deeper scratches or trolley scuffs, but it was easy to apply, polished up quickly delivers a really impressive shine and water-repellence that helped to keep the paint looking great for days. It does exactly what you want a polish to do and, for the money, you just can’t knock it.  Autocar says 4 stars

3. Turtle Wax Renew Polish – Best budget buy

Price: £6.10

Buy from: Amazon

Min price per litre: £12.20

The Turtle Wax goes on really nicely and polishes up quickly, buffing with very little effort to a glossy, high shine that also leaves the paintwork smooth to the touch. Deeper scratches are better served with the T-Cut or Meguiar’s but for working out the general haze and dullness of years of ungaraged life and daily use, the Turtle Wax does a really fine job. As a general polish that leaves the paint looking fresh for many days afterwards, this is a solid choice at a great price.

4. Autoglym Super Resin polish

Price: £10.89

Buy from: Amazon

Min price per litre: £33.51 

The Super Resin polish does a good job of proving why Autoglym is consistently such a popular, trusted brand when it comes to car care. It did wonders for out lightly abused BMW’s paintwork, bringing a bright shine and glossy finish that resisted fading for many days afterwards. It’s not as good as the Meguiar’s when it came to buffing out deeper scratches, but if you want a high quality, long lasting shine-and-protect polish that really repels water and muck as well as bringing an instant shine, the Autoglym is one of the best out there.

5. T-Cut Colour Fast

Price: £11.99

Buy from: Amazon

Min price per litre: £23.98 

T-Cut remains a household name when it comes to polish, and we can see why from the results that this colour-specific polish delivered. It’s intended to be particularly good for deeper scratches, with the pigment of the polish helping to blur out the damage. It works, too. We had a lightly vandalised white Corsa in mind when we chose to try this T-Cut product, and the polish worked wonders on the key-mark, polishing out the worst of it out so that it was only visible where the scratch was very deep. It also comes with great polish and buffing pads.

6. Sonax car polish

Price: £9.80 (250ml)

Buy from: Amazon

Min price per litre: £21.10

Ironically, the only English on the Sonax’s packaging is the phrase ‘Made in Germany’, which is self-evident given that everything else is in German, including the instructions. Thankfully, polish isn’t complicated to use and the Sonax proved to be very good. It does dry a little too quickly than is always convenient, but it did a good job of bringing the paint’s colour and metallic finish, leaving it smooth to the touch and impressively shiny. Not the cheapest, and with a few linguistic challenges that we weren’t expecting, but ultimately a good product.

7. MER Ultimate Shine Polish

Price: £12.88

Buy from: Amazon

Min price per litre: £12.88 

You can only get the Mer in a 1.0-litre container, which is fine but may be a pain if you haven’t got loads of space to store it. The child-proof cap is also so effective that it’ll keep most able-bodied and hearty adults from getting the lid off, never mind if you’re unfortunate enough to suffer from arthritic hands. Still, if you’ve got the shelf space and the strength to live with it, the Mer polish does the job. It left our battered BMW’s paint looking bright and free of the worst of the haze and marks. It doesn’t seem any better than cheaper options here, though, and it doesn’t remove deeper scratches as well as our more highly-rated polishes.
