The marketing claim
“Natural power of white vinegar”
The chemical reality
Astonish’s vinegar spray is acetic acid (CAS 64-19-7) at under 5% plus a drop of surfactant and perfume. Diluting 80% acetic acid 1:19 lands in the same band as the trigger bottle — without the citrus markup. This is not citric (Cillit Bang / Cif) and not soda crystals.

The Marketing Claim & The Catch
A 750 millilitres pack of Astonish White Vinegar Multi-Purpose Cleaner typically retails around £1.30 in household cleaning. That is a UK shelf-price snapshot for the maths on this page — not a live shop quote or a manufacturer RRP. Listings, sizes and deals move. The marketing line is that you are buying a finished lifestyle product, not a weighed chemical.
On the pack: Natural power of white vinegar; Cuts limescale, grease and everyday grime; and Zesty citrus — vegan and cruelty-free.
The catch: Astonish’s vinegar spray is acetic acid (CAS 64-19-7) at under 5% plus a drop of surfactant and perfume. Diluting 80% acetic acid 1:19 lands in the same band as the trigger bottle — without the citrus markup. This is not citric (Cillit Bang / Cif) and not soda crystals.

Proprietary Blend & Dosage Breakdown
The labelled active is Acetic acid at 5%. Everything else in the pack is water, non-ionic surfactant and perfume.
At 5% active, most of what you pay for is carrier and packaging. The brand is selling convenience, fragrance and a label — not a uniquely potent molecule.
Branded working strength is whatever comes out of the bottle. The bulk alternative is 80% Acetic acid 80% (diluted to ~4.5% w/v), mixed to 1:19 (50 ml of 80% in 950 ml water ≈ Astonish <5%).

The Active Chemical Alternative (Dupe Stack)
The dupe stack is Acetic acid 80% (diluted to ~4.5% w/v) at 80% bulk. Indexed as CAS 64-19-7, formula CH3COOH. Buy it as 5 litres for around £44.95 from Amazon UK.
Working strength: 1:19 (50 ml of 80% in 950 ml water ≈ Astonish <5%). Indicative cost £0.45 per diluted litre — 70% below a typical branded pack on a per-litre basis, before you reuse leftover bulk.
Follow the mixing method and the supplier SDS. Wear the listed PPE. Do not mix incompatible oxidisers, acids or ammonia.
- Corrosive concentrate. Gloves, splash goggles. Always add acid to water — never water to 80% acetic. Work in ventilation; the vapour is sharp.
- Pour 50 ml of 80% acetic acid into 950 ml of cold water in a labelled trigger bottle (1:19). A drop of washing-up liquid matches the branded grease cut.
- Spray, leave a minute, wipe. Rinse food-contact surfaces, plastics and metal. Do not use on marble, limestone, gold-plated taps or stone you care about.
- 5 litres of 80% at 1:19 makes about 100 litres of 5%-band spray — more than 130 Astonish bottles.
- Store the jerry locked and labelled. Do not mix with bleach, ammonia or bicarbonate in one bottle.

Active ingredient and cheaper alternative — FAQ
Is vinegar the same as Cillit Bang?
Same job family (mild acid on limescale film) but different molecules. Cillit Bang is often citric and/or sulfamic. This spray is acetic acid — the acid in vinegar. Pick the teardown that matches the bottle you hold.
Can I mix vinegar spray with bicarbonate or bleach?
Not in one bottle. Vinegar plus bicarbonate fizzes and cancels. Vinegar plus hypochlorite bleach risks chlorine gas. One chemistry, then rinse.
How do you mix the White Vinegar Multi-Purpose Cleaner dupe stack?
Corrosive concentrate. Gloves, splash goggles. Always add acid to water — never water to 80% acetic. Work in ventilation; the vapour is sharp. Pour 50 ml of 80% acetic acid into 950 ml of cold water in a labelled trigger bottle (1:19). A drop of washing-up liquid matches the branded grease cut. Spray, leave a minute, wipe. Rinse food-contact surfaces, plastics and metal. Do not use on marble, limestone, gold-plated taps or stone you care about. 5 litres of 80% at 1:19 makes about 100 litres of 5%-band spray — more than 130 Astonish bottles. Store the jerry locked and labelled. Do not mix with bleach, ammonia or bicarbonate in one bottle.
