Frequently asked questions about the Car shampoo category
What is car shampoo?
Car shampoo is a specialized cleaning agent for removing dirt, dust and road grime from a vehicle’s body. It gently cleans while protecting paintwork and adding shine; available as concentrates, wax-containing formulas and products for contactless/foam washing.
How does concentrated car shampoo differ from regular?
Concentrated car shampoo must be diluted with water per instructions (commonly 1:10 to 1:100), making it more economical. It delivers the same cleaning power with lower consumption and is suitable for foam generators and manual washing.
When to choose a car shampoo with wax?
Choose a car shampoo with wax when you want cleaning plus a protective layer and extra shine. These products are good for regular maintenance and provide temporary hydrophobic protection without separate polishing.
Is car shampoo suitable for contactless washing?
Use shampoos labelled for contactless washing or foam use — they’re formulated for foam generators and dissolve dirt without scrubbing. The category includes Grass Active Foam and Active Foam Extra products designed for contactless application.
How to use car shampoo for manual washing?
Dilute concentrate per instructions or use ready-made shampoo in a bucket of warm water, apply with a soft sponge or mitt, rinse with clean water and dry with a microfiber towel. Wax shampoos should be worked gently to preserve the protective layer.
Can I use a universal cleaner instead of car shampoo?
Universal cleaners (e.g. Universal Cleaner 5.4 kg Grass) work for heavy dirt and specific parts, but a specialised car shampoo is preferable for the body — it’s gentler on paintwork and provides shine/protection.
Which shampoos in the range suit heavy dirt?
For heavy dirt use Grass Active Foam Power and Active Foam Extra series and concentrated heavy-duty cleaners. They’re formulated to dissolve ingrained grime and oil residues without damaging the paint.
What is shampoo consumption for manual wash and foam generator?
Consumption depends on dilution: ready-made shampoos use more — about 20–50 ml per 10 L water; concentrates are diluted (e.g. 1:50–1:100). When using a foam generator, dilute concentrates according to the foam unit and shampoo instructions.
Can car shampoo be used to clean the interior or engine?
No — shampoos for the exterior are not suitable for interior or engine cleaning. Use specialised products: Textile Cleaner for upholstery and Motor Cleaner/engine cleaners from the Grass range for engine parts.
Which products in the catalogue suit regular maintenance and shine?
For regular maintenance and shine choose wax-containing car shampoos (e.g. CAR SHAMPOO WITH WAX HG 1L) and light concentrates like Active Foam Light/Active Foam Magic, which clean and give a glossy finish without aggressive action.
