SONAX Xtreme Auto Shampoo 2-in-1, 1 Litre

SONAX Xtreme Shampoo 2-in-1 is a concentrated car wash formula that combines deep cleaning power with a built-in drying aid that causes water to sheet off painted surfaces, reducing drying time and water spot formation. The 1-litre bottle produces multiple washes when diluted according to the recommended ratio, making it an economical choice for regular vehicle maintenance.

The pH-neutral formula is safe for all automotive paint types, clear coats, plastic trim, rubber seals, and glass surfaces. It lifts and suspends road grime, insect residue, tree sap, and general soiling in a rich foam that can be applied by hand wash mitt, sponge, or foam cannon. The integrated drying accelerator modifies the surface tension of rinse water, causing it to run off in broad sheets rather than forming droplets that can leave mineral deposits as they evaporate.

SONAX recommends adding approximately 25–50 ml of product to a bucket of warm water for hand washing or using the concentrate directly in a foam lance for pre-wash application. The shampoo rinses cleanly without leaving residue or film on the paint surface. It is compatible with existing wax and sealant coatings and will not strip protection from previously treated surfaces. SONAX is a German automotive care brand with over 70 years of experience in vehicle cleaning and protection products. The Xtreme range represents their premium product line.
