shampoo
sham-POO
/ʃæmˈpuː/
A specialized, pH-neutral soap designed to lubricate and clean automotive paint without stripping waxes or sealants.
Automotive shampoo is highly concentrated and engineered to produce thick suds that lift and suspend dirt away from the paint surface, preventing scratches during washing.
The story behind the word. The word shampoo has a fascinating origin, coming from the Hindi word 'cā̃po', which meant to massage or knead the scalp. Introduced to Britain in the 18th century as a head massage treatment, the term eventually shifted from the physical act of massaging to the liquid soap used during the wash, and finally to specialized cleaners for cars and carpets.
