Autoglym Ultimate Screenwash, Concentrated 500ml review
Drivers who want one bottle that handles both summer bug/grime removal and proper sub-zero winter screen protection.
By Tom Calder · Price last checked 20 Sep 2026, 12:29 BST · price-tracked
A genuinely versatile concentrate rather than a single-use product: dilute it weak for everyday summer topping-up or strong for real freeze protection, so one small bottle replaces several seasonal screenwashes. A sensible, low-drama boot-kit staple.

We may earn a commission when you buy, or a fee when you request a quote, through our links — it never affects what we recommend.

- Adjustable dilution covers -1°C (weak mix) right through to -45°C neat, so it works year-round
- Concentrate makes up to 8 litres, working out cheaper per litre than ready-mixed jugs
- Safe on paintwork, trim and headlight washer jets
- You have to measure and mix it yourself — no ready-to-use option at this size
- Stronger winter dilutions use the bottle up faster than a pre-diluted jug
Who shouldn't buy this
You'd rather not measure and mix — buy a pre-diluted 5L winter screenwash jug instead and skip the dilution step.
