Soft99 Water Block Shampoo White: pH Balanced Hydrophobic Shampoo

Add the recommended dose to a wash bucket filled with water and agitate to build a rich lather. Wash panels with a quality wash mitt using the two-bucket method, working from the roof down. Rinse each panel thoroughly and dry with a clean microfibre. The hydrophobic agents work best when the surface is rinsed off quickly before drying.

Yes. The formula is pH-balanced and gentle enough not to degrade ceramic coatings, paint sealants or carnauba waxes. It's designed to maintain and lightly reinforce the hydrophobic properties of whatever protection layer is already on the paint.

The optical brighteners in this variant are calibrated for white and light-coloured paint. Using it on dark or black paint won't cause damage, but you won't get the full optical benefit. Soft99 offers colour-matched Water Block Shampoo variants for dark and silver paint, so choose the one matched to your vehicle's colour for the best result.

Not as a long-term standalone. The hydrophobic agents boost and maintain existing protection, but they're not a substitute for a wax, sealant or coating applied to bare paint. Think of it as a maintenance product that keeps your base layer performing between full detail sessions.

Refer to the product label for Soft99's recommended dilution, as it can vary by container size and water hardness. As a general guide for a 10-litre wash bucket, a cap-full or two builds ample lather for a full vehicle. More product won't necessarily increase protection, so follow the label guidance.

Yes, Water Block Shampoo can be used in a foam lance for a pre-wash or contact-wash stage. Adjust the dilution to suit your lance's output ratio - typically a higher concentration than a bucket wash. The foam clings well and the hydrophobic agents remain active through the rinse.

The hydrophobic components in the shampoo deposit a light water-repellent layer with each wash. On a coated or sealed surface, you'll notice tighter, more defined beading immediately after rinsing. On unprotected paint the effect is more subtle. Consistency is key - regular use builds cumulative hydrophobic behaviour over time.

The shampoo is primarily formulated for painted bodywork, but it's gentle enough for glass and most plastic trim. On wheels, it will clean light brake dust and road grime, though heavily contaminated wheels may need a dedicated wheel cleaner first. Always rinse wheel surfaces thoroughly, especially if they are hot after driving.
