— Water-Softening Car Shampoo
pH-Neutral Car Shampoo for Hard Water Conditions.
Aqua Soft Shampoo is a pH-neutral car shampoo for hard water,
created for drivers and detailers who want a smoother contact wash and
a cleaner drying stage. Its water-softening action helps reduce the
calcium and magnesium deposits that can remain after rinsing.
The formula delivers very good lubrication, dense foam and easy rinsing,
and is safe for ceramic coatings, waxes and PPF, making it a
practical choice for regular maintenance on protected and unprotected vehicles.
For everyday washing without the hard-water focus, see
Pure Shampoo.

Reduce loose contamination before contact washing, maintain lubrication
with a dedicated microfiber wash mitt, then dry the vehicle promptly so
mineral-rich water has less time to evaporate on the paint.
It helps reduce the effect of calcium and magnesium in the wash
water, supporting a cleaner rinse and easier drying.
Is Aqua Soft safe for ceramic coatings?
Yes. Its pH-neutral formula is suitable for ceramic coatings,
waxes, PPF, paint and chrome during regular maintenance washes.
Does it remove existing water spots?
It does not remove existing water spots. It helps reduce
fresh mineral deposits during washing. Existing mineral buildup may
require an acidic shampoo or dedicated treatment.
How much shampoo should I use?
Add 20–50 ml per 10 litres of water (about 0.7–1.7 fl oz
per 2.6 US gal), depending on the wash conditions and the level of
contamination.
Is pH-neutral car shampoo the same as car wash soap?
Yes. "Car wash soap" is the more common term in the US, while
"car shampoo" is more widely used in detailing circles and in
the UK. Aqua Soft Shampoo works as both — a pH-neutral car wash
soap for regular maintenance washes.
