Description
Introducing the Kärcher House & Siding cleaner: Highly concentrated and specially formulated for cleaning houses, buildings, siding, and other structures, it effectively removes environmental dirt, grime, algae, mold, and mildew stains. This concentrated formula makes up to 40 gallons of cleaning solution, perfect for heavy-duty cleaning jobs. Fast-acting and designed for tough pressure wash jobs, it rinses clean without leaving any residue. This phosphate-free and powerful formula cleans, brightens, and restores various surfaces including vinyl, aluminum, fiber cement, wood, gutters, roofing, brick, and stucco.
Directions: Pour it into your pressure washer's onboard detergent tank or connect the siphon tube to the product container. Refer to your pressure washer owner's manual for specific instructions. Adjust the metering valve if available to achieve the desired strength.
For optimal results, start spraying from the bottom up, allowing the detergent to penetrate surface dirt for 1-5 minutes. Avoid letting it dry. Rinse the surface at high pressure with clean water. For stubborn dirt, a soft bristle brush can be used. Remember to wash from the bottom up and rinse from the top down for the best outcome.
If you prefer using a foam cannon, the Kärcher House & Siding cleaner can be easily applied by placing it in the foam cannon bottle. Adjust the foam cannon metering valve to your desired strength and follow a similar washing process as described above.
For manual application, dilute the detergent by mixing 1 part with 39 parts water. Adjust the strength according to your needs. Apply the solution to the surface for 1-5 minutes, ensuring it doesn't dry. Rinse with high pressure from the top down.
Notes: Always test on an inconspicuous area first. Before starting, saturate any surrounding vegetation with water. Once cleaning is complete, repeat saturating vegetation.

Great pressure washer soap!
[This review was collected as part of a promotion.] The Deck and Fence Cleaner Pressure Washer Soap is a good product for cleaning. We used it to clean my parents' concrete back porch. It worked really well, taking off years of stains. I absolutely loved the scent. It was weird how lovely it smells. Great value for the money. I received this product as a complimentary sample to test and review.

great soap to get ready for summer backyard partie
[This review was collected as part of a promotion.] This deck cleaner made it so much easier to power wash and effectively clean dirt and get stains off our deck. Perfect way to get the backyard ready for summer. The scent was also really pleasant and felt like a luxurious treatment for our wood. Love that it’s a concentrate that will last us for summers to come!

Made cleaning up outback super easy!
[This review was collected as part of a promotion.] I was excited to receive the Karcher Deck and Fence Cleaner to use with my new pressure washer and have honestly been so impressed by its efficacy. Our deck has been looking pretty worn out and covered in that usual layer of dirt and grime that builds up over time. This stuff made the whole process so easy. It foams up really well, sticks to the surface long enough to actually clean, and rinses off without leaving behind any streaks or residue. I didn’t have to scrub like crazy either which was a win in my book! Everything looked so much brighter and cleaner after I finished. Definitely keeping this on hand for the next round of outdoor cleanup.

Fresh scent and powerful clean
[This review was collected as part of a promotion.] The Karcher 1 Gal. Cleaner smells great and did a fantastic job removing dirt, algae, and mildew from my deck. It’s powerful, easy to use with a pressure washer, and one gallon goes a long way—up to 36 gallons. Great value, great results.

Works well for fencing
[This review was collected as part of a promotion.] I received the Kärcher Deck and Fence Cleaner, 1 Gal, Pressure Washer Soap complimentary for my honest review. This is an extremely easy to use product, especially if you have a pressure washer. It is a concentrate so you add it into your canister for best results. While spraying this on and washing off, it really made a great difference in removing the dirt and grime on my fence. We live in a hot and humid climate and we easily get build up on our fence despite our best efforts. After spraying this on and washing it off, we saw noticeable results and those results have lasted over the last week. It is extremely easy to use. The packaging is easy to open. And it has made a great difference. I would recommend this for anybody who has deck or fencing that they need to clean for mold, mildew, or algae

Great product, 5 stars ⭐️
[This review was collected as part of a promotion.] I tried this Deck and Fence Cleaner for use with my pressure washer, and wow, what a difference! It tackled years of dirt, mold, and grime on both my wooden deck and vinyl fence. The formula is super concentrated, so one gallon goes a long way (I easily mixed up enough for multiple cleaning sessions). It foams up just enough and rinses off clean, with no residue left behind. What I love most is that it’s phosphate-free but still incredibly effective it even removed some old iron stains I thought were permanent. My outdoor space looks refreshed and ready for summer. If you’re looking for a reliable cleaner that works fast and delivers real results, this is it. Highly recommend!

Clean deck!
[This review was collected as part of a promotion.] This fence cleaner is just what we’re looking for, after a bad polen season we found that our deck was turning yellow. We used a washer pressure to clean deeply, of course this cleaner helped a lot. It has a great scent and great eco friendly product.

Cleans well, smells fresh, eco-friendly, and gets
[This review was collected as part of a promotion.] Used this with my pressure washer and it cleaned my deck and fence really well, dirt and mildew came off easily, and the wood looked refreshed. The scent is light and clean, not harsh or chemical-like. I also like that it’s labeled as environmentally friendly, which gives me peace of mind when using it outdoors. Directions could be clearer, but overall it’s a solid, effective cleaner.

Works great
[This review was collected as part of a promotion.] We have only done one wash with it so far, and it did amazing. Our deck and ramp look so much better, and It got the slick slime stuff off, so now we don't slip and fall when it rains. I don't really get much of a scent from it but it definitely works.
