Karcher Foam Cleaner: Professional-Grade Cleaning at Home

Keeping your car, outdoor furniture, and patio surfaces spotless can be difficult with just water and pressure. Grime, mud, bird droppings, pollen, grease, and air pollution all cling to surfaces stubbornly. If you’ve ever wished for that same showroom-clean effect you see at professional car washes or detailing studios, the Karcher foam cleaner brings that experience directly to your home.

Specially formulated for Karcher pressure washers, this ultra foam detergent creates a rich, thick foam that clings to surfaces and lifts dirt efficiently — saving you time, effort, and frustration.

Create a Thick Foam Blanket That Does the Work for You

The key to this cleaner’s performance is the ultra-dense foam it generates. When sprayed with a Karcher foam nozzle or Plug & Clean system, it forms a deep layer of white foam that clings to vertical and horizontal surfaces alike.

Instead of running off immediately, the foam remains in place, loosening stubborn dirt, softening dried-on stains, and giving the detergent time to break down oils, dust, and residue. You simply rinse away the foam — and the grime goes with it.

Safe and Powerful on All Exterior Surfaces

One of the standout benefits of the Ultra Foam Cleaner is its versatility. While powerful against dirt, it is also gentle on all common outdoor and vehicle surfaces, including:

• Automotive paint (including matte and ceramic-coated finishes)

• Chrome and alloy wheels

• Plastic bumpers and trims

• Glass and mirrors

• UPVC window frames

• Painted fences and garden walls

• Wooden, rattan, and metal outdoor furniture

This makes it ideal not only for cars but also for homeowners who want to maintain the cleanliness and appearance of their entire exterior space.

Perfect for Quick and Safe Car Cleaning

This foam cleaner was designed with vehicle owners in mind. It loosens traffic film, brake dust, bird droppings, and oily road grime without needing brushes or scrubbing. Just foam, wait a couple of minutes, and rinse.

It’s especially useful if you:

• Wash your car regularly and want to reduce contact cleaning

• Use a snow foam as a pre-wash before shampooing

• Want to maintain a ceramic-coated or waxed car

• Detail your bike, scooter, or van at home

It’s the first step to a scratch-free car wash — helping lift dirt so you don’t drag it across your paintwork during contact washing.

Great for More Than Just Vehicles

Though ideal for cars, the Karcher foam cleaner also delivers exceptional results on other outdoor surfaces:

• Patios and block paving: Removes moss, algae, and grime

• Plastic bins and containers: Deodorizes and freshens

• BBQs and outdoor cooking areas: Cuts through grease buildup

• Window shutters, frames, and conservatories: Brightens and restores

• Garage doors and driveway gates: Removes weathering marks and stains

Because it’s safe on painted and plastic surfaces, you can use it liberally across many areas without worry.

Ready for Use with Karcher Plug & Clean and Foam Nozzles

For users of Karcher pressure washers that support the Plug & Clean system, the bottle connects directly to the unit — no mixing, measuring, or pouring required. The machine draws detergent directly, ensuring consistent foam every time.

For other models, simply pour the cleaner into a foam sprayer or bottle attachment, dilute it with water (typically 1:5 to 1:10), and apply. The result is the same: thick, shaving-cream-like foam that does all the heavy lifting.

Fast Application Saves You Time

This cleaner is a huge time-saver. You can apply a full coat of foam over your car or patio in less than 2 minutes. After a brief dwell time, rinse with your pressure washer — job done.

There’s no need to pre-soak or scrub, and because it’s efficient, you use less water and less effort overall. For regular maintenance or weekly washes, it cuts your cleaning routine in half.

Economical and Long-Lasting Formula

Each 1-litre bottle of Karcher foam cleaner lasts longer than you’d expect. Because it’s highly concentrated, just a small amount delivers big results. You’ll typically get:

• Up to 10 full vehicle washes

• 3–4 large patio cleaning sessions

• Multiple rounds of garden furniture cleaning

• Extended use in high-traffic outdoor areas

Its long shelf life and wide application range make it one of the most cost-effective ways to boost your cleaning game.

Gentle on the Environment and Your Garden

This detergent is biodegradable and phosphate-free, meaning it breaks down safely after use and won’t pollute your garden or drains. Used correctly and rinsed thoroughly, it won’t harm plants, pets, or wildlife.

You can confidently wash near lawns, flower beds, vegetable patches, and children’s play areas without worrying about long-term environmental impact.

No Streaks, No Residue—Only Shine

After rinsing, you’re left with a clean, smooth surface with no streaks or residue. Unlike some harsher soaps, this cleaner doesn’t leave behind chalky marks, and it won’t dull painted or plastic surfaces.

Use it regularly and you’ll see your vehicle, furniture, and hard surfaces stay cleaner for longer between washes, with a visible improvement in gloss and finish.

Ideal for All Seasons and Weather Conditions

The Karcher foam cleaner isn’t limited to summer use. In winter, it removes salty road grime from your car. In autumn, it cleans leaf stains and mildew from decks. In spring, it freshens outdoor spaces after months of rain and wind.

It’s your all-season cleaning solution for all outdoor surfaces.

How to Get the Most from Your Foam Cleaner

• Shake well before use

• Store upright in a cool, shaded area

• Rinse the foam sprayer or lance after each use to prevent buildup

• Never let the foam dry — always rinse before it starts to evaporate

• Dilute correctly for optimal coverage and performance

Proper care and storage ensure every bottle gives you consistent, powerful results until the last drop.
