Karcher Foam Cleaner: Deep-Cleaning Power for a Spotless Finish

When it comes to car detailing, patio cleaning, or removing stubborn grime from outdoor surfaces, water pressure alone isn’t always enough. The right cleaning solution can make all the difference—and that’s exactly where the Karcher foam cleaner steps in. Specially formulated for use with Karcher pressure washers, this ultra foam detergent offers thick, long-lasting coverage and powerful cleaning action for a wide range of surfaces.

Whether you’re cleaning your car, motorcycle, garden furniture, or stonework, this foam cleaner turns a regular rinse into a professional-grade clean with minimal effort.

Engineered for Maximum Foam Performance

The Karcher Ultra Foam Cleaner (62957430) is not just any detergent. It’s designed to produce rich, clingy foam that sticks to surfaces for longer, giving the formula time to loosen dirt, grease, and road film. This extended contact time is key in breaking down heavy contamination, making the rinsing process much more effective.

Unlike cheap, watery soaps that run off in seconds, this foam grips paint, glass, metal, and plastic surfaces, ensuring deep and even cleaning without damaging the surface underneath.

Perfect for Car and Motorcycle Cleaning

This cleaner truly shines when used on vehicles. If you’re tired of swirl marks, water streaks, and leftover grime after every wash, the Karcher foam cleaner transforms your car washing routine. Applied through a Karcher foam nozzle or Plug & Clean system, it covers your car in a dense white layer of foam that lifts away:

• Road grime and tar

• Bird droppings

• Tree sap

• Brake dust

• Diesel stains

• General urban pollution

It’s safe for paintwork and won’t strip wax or sealants. Whether you’re washing a car, van, camper, or motorbike, this cleaner creates that glossy, streak-free finish every vehicle owner wants.

Gentle on Surfaces, Tough on Dirt

While the foam cleaner delivers powerful results, it remains pH-neutral—making it safe for delicate finishes like ceramic coatings, chrome, clear plastics, and polished metal. This makes it an excellent choice for high-end cars, electric scooters, e-bikes, and even carbon-fiber components.

You can also use it with confidence on:

• Garden tools

• Plastic or rattan garden furniture

• Painted metal gates and fences

• Outdoor toys and playsets

• PVC window frames and doors

Its versatility means one bottle serves multiple uses, saving you money on specialized products.

Ideal for Use with Karcher’s Plug & Clean System

The Karcher Ultra Foam Cleaner is part of the Plug & Clean range—designed to fit directly into your Karcher pressure washer (on compatible models like K4, K5, and K7). This system allows the detergent to be pulled automatically through the lance, producing thick foam without needing to mix manually.

If your pressure washer doesn’t have Plug & Clean compatibility, you can still apply it using a foam nozzle or foam sprayer accessory. Simply pour the cleaner into the bottle, dilute as needed (usually 1:5 to 1:10 with water), and apply.

Long-Lasting Value in Every Bottle

Each 1L bottle of Karcher foam cleaner goes a long way. Thanks to its concentrated formula, you only need a small amount per use. When properly diluted, one bottle can provide up to 10 car washes or multiple patio cleaning sessions.

This makes it a cost-effective solution compared to single-use foam sprays or household soaps that offer less coverage and less cleaning power.

Safe for Use Around Plants and Pets

Another benefit of this formula is its biodegradable and non-toxic nature. When used correctly and rinsed thoroughly, it won’t leave harmful residues on driveways or harm your garden’s plants. This makes it suitable for cleaning around pets, children’s play areas, and vegetable patches—as long as rinsing is done properly.

Environmentally responsible homeowners will appreciate that this cleaner is free from aggressive chemicals, abrasives, and artificial brighteners.

Transforms Pressure Washing into Professional Detailing

Pairing this foam cleaner with your pressure washer instantly upgrades your equipment into a professional-grade detailing machine. The foam pre-treatment loosens grime before high-pressure water is applied, reducing the need for physical scrubbing and lowering the risk of scratching surfaces.

The result is a more efficient, effective, and safe cleaning session—especially valuable when maintaining polished or high-gloss surfaces.

Streak-Free Finish Every Time

Because the foam lifts away dirt rather than smearing it, rinsing leaves behind a spotless, residue-free surface. You’ll notice an immediate improvement in:

• Gloss retention on paintwork

• Shine on metallic surfaces

• Clarity of glass and mirrors

• Clean scent after each wash

No more chalky residue or water marks—just a smooth, factory-fresh look.

Easy Application and Quick Rinse

To use, simply apply a layer of foam using your foam sprayer or Plug & Clean system. Allow it to sit for 2–5 minutes (do not let it dry), then rinse off with your pressure washer. For tougher areas, a soft detailing brush or microfiber mitt can be used for added agitation.

Thanks to its efficient coverage and gentle chemistry, it simplifies the cleaning process without compromising on results.
