Requiring filter removal and a 2-hour soak, this pre-mixed, biodegradable formula safely restores airflow and engine performance without harming catalytic components, making it the go-to choice for workshops aiming to extend filter life and optimize fuel efficiency. ## Description A powerful solution for Diesel Particulate Filters (DPFs) that are severely clogged beyond the point of standard regeneration. Designed for professional workshop use, this heavy-duty cleaner is intended for DPFs with over 70% soot loading, where conventional regeneration methods have proven ineffective. It provides an in-depth cleaning process that requires the filter to be removed from the vehicle, ensuring direct application and maximum penetration of the chemical solution. With approximately two hours of soak time, it effectively dissolves soot, ash, and other particulate matter, allowing the DPF to be restored to proper functionality. This cleaner is pre-mixed and ready to use, eliminating the need for dilution and ensuring a precise chemical balance for effective results. Simply remove the DPF from the vehicle, apply the solution, and allow it to soak for the recommended duration. The specially designed formula works to break down contaminants deep within the filter, restoring optimal airflow and improving overall engine performance. Manufactured with a biodegradable composition, it is safe for use on all DPF types and does not interfere with the catalytic elements present in the filter. This guarantees that the emissions system remains intact while benefiting from a complete and thorough cleaning. A blocked DPF can cause numerous performance issues including reduced acceleration, increased emissions, and higher fuel consumption. By restoring the filter to its correct pressure levels, this cleaner ensures better engine efficiency and prolonged component lifespan. A must-have solution for professional workshops and automotive specialists dealing with critically blocked Diesel Particulate Filters, this cleaner provides a reliable, effective, and environmentally friendly way to restore performance and reduce the need for costly filter replacements. ## Features - ✅ HEAVY-DUTY CLEANING SOLUTION FOR SEVERELY BLOCKED DPFs: Designed specifically for Diesel Particulate Filters (DPFs) that are heavily clogged with more than 70% soot loading. When standard regeneration methods fail to restore the filter’s functionality, this cleaning solution provides a powerful alternative. Formulated to break down stubborn soot, ash, and other particulate matter, it effectively eliminates obstructions that hinder proper engine performance. - ✅ PROFESSIONAL-GRADE IN-HOUSE WORKSHOP CLEANING FORMULA: Developed as a specialised workshop solution, this formula is designed for professional use when dealing with critically clogged DPFs. Unlike standard cleaning additives, this advanced chemical formulation requires the removal of the filter from the vehicle to ensure thorough cleaning. By soaking the DPF for approximately two hours, the solution penetrates deep into the filter’s structure, dissolving accumulated deposits and restoring airflow. - ✅ READY-TO-USE AND EASY APPLICATION FOR MAXIMUM EFFECTIVENESS: This DPF cleaner is pre-mixed and does not require any dilution, simplifying the cleaning process and ensuring precise chemical composition. For proper application, the Diesel Particulate Filter must be dismounted from the vehicle before treatment. Once removed, the solution is applied directly to the filter, allowing it to soak for the recommended time to maximise cleaning performance. No complex preparation or mixing is required, making the process straightforward while delivering exceptional results. - ✅ SAFE, BIODEGRADABLE FORMULATION FOR ALL DPF TYPES: Manufactured with a biodegradable composition, this cleaner is safe for use on all types of Diesel Particulate Filters. The carefully developed formula ensures that it does not affect the function of the catalytic elements present in the filter, maintaining the integrity of the emissions system. It is designed to remove contaminants without causing damage to delicate components, making it a reliable solution for restoring blocked DPFs while prioritising environmental responsibility. - ✅ RESTORES PROPER DPF PRESSURE LEVELS AND ENGINE PERFORMANCE: By effectively eliminating blockages caused by soot, ash, and other harmful contaminants, this cleaner plays a crucial role in restoring the DPF to its correct pressure levels. A clean DPF allows the engine to function as intended, reducing backpressure and improving fuel efficiency. Vehicles struggling with poor acceleration, increased emissions, and frequent regeneration cycles can benefit from this deep-cleaning treatment, ensuring smoother performance and prolonged filter life. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B07ZDQ2J8B | | Best Sellers Rank | 1,310 in Automotive (See Top 100 in Automotive) 43 in Fuel Systems | | Brand | Wynn's | | Customer Reviews | 4.6 4.6 out of 5 stars (716) 4.6 out of 5 stars | | Date First Available | 2 May 2018 | | Guaranteed Software Updates Until | unknown | | Item Model Number | 18985 | | Item Weight | 5.32 kg | | Manufacturer | Krafft | | Manufacturer Part Number | 18985 | | Model | 18985 | | Product Dimensions | 4.6 x 8.4 x 21.6 cm; 5.32 kg | ## Images ![Wynn's Off-Car Diesel Particulate Filter Cleaner - Heavy-Duty Cleaning - 5L - Image 1](https://m.media-amazon.com/images/I/81BQyOcsxhL.jpg) ![Wynn's Off-Car Diesel Particulate Filter Cleaner - Heavy-Duty Cleaning - 5L - Image 2](https://m.media-amazon.com/images/I/71t1mgdGU9L.jpg) ![Wynn's Off-Car Diesel Particulate Filter Cleaner - Heavy-Duty Cleaning - 5L - Image 3](https://m.media-amazon.com/images/I/81+EXqH-TCL.jpg) ## Questions & Answers **Q: Can use this to clean turbo ..** A: Hi, it's a powerful cleaner, so might work, but you're better off using a turbo cleaner. **Q: does this product actually remove ash from the DPF?** A: A mechanic did my van but from what he told me you pour the whole tube in then leave it for 20-30 minutes, then start the vehicle then let it run on idle, this is when you get a grey to black foam out the rear of the exhaust. It works very well **Q: Can this be used with dpf in situ or does it need to be removed and washed through ?** A: Yes you can. Ideally you want spray it in so it foams up to agitate the soot/Ash. Make sure the engine itself is warm or up to operational temperature for better results. Once sprayed in leave it for 15 to 20mins or so to soak in. Ideally you want to see the dpf pressure readings when starting the engine and keep the revs around the 3k mark.. The pressure readings will drop gradually as the dpf heats up. You want to do this with the car stationary. Please check your engine oil level is fine before starting the car. You can use 2.5 litres to start with and if the dpf pressure has not dropped to satisfactory levels you can use the remaining 2.5ltrs and repeat the procedure. **Q: Do i have to put this inside my diesel car tank? Or how do i use it?** A: Hi There, with this product it’s not to be used inside your diesel tank. You will need to take the DPF off the car, and soak it in this product for a few hours. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as it should. 5***** *by on Reviewed in the United Kingdom 22 September 2026* Wonderful stuff. Tried many a different snake il recently to unblock an old Saab 9-3 with a heavily clogged DPF. I used this and applied using a 5-litre pump bottle sprayer via the pressure sensor pipe. The Saabs have this high up, easily reached and the DPF itself is very low down, so little or no risk of anything going the 'wrong way' into the turbo or valve gear. Left it about 4 or 5 hours. Used half, so 2.5 Litres. Popped the pipe back on and ran it on tick over after the 5 hours and wow, what a load came out! Caught as much foam as I could, plenty of it, black as soot, thankfully. Then as soon as foam finished, as engine got hot, car heated up and then steam / smoke. Took it out for a few miles and drove it like I stole it. Light went out. Doube checked and reset the DPF and all is good. Literally 50 or more BHP, like it was new again. Car has 130k miles done, so very pleased. 5*****. I had used the 1 litre pack of Ash-X, but although it made a good effort, it was nothing close to the Wynns. 5* and I have half left for another day. ### ⭐⭐⭐⭐⭐ works great, in depth review *by on Reviewed in the United Kingdom 26 June 2024* I used this on a blocked Transit van DPF with a soot content of 350%, I blanked off the inlet side of the DPF and all the pipes and holes then filled it up from where the exhaust would normally exit and left it for 2 days soaking and only agitated it 4 times over the 2 days then drained in to a bucket, back flushed it with hot water then carefully with a jet wash ( NOT A STEAM CLEANER) until the water coming out ( with agitation while draining) run clean, I let it drain out for a few days but after fitting and running there was still water in it so I let the engine dry it out on idle. the DPF differential psi is good at 6kpa but after cleaning it was 2 kpa, originally its kpa on idle was much higher and owing to the soot content at 350% the DPF needed removingI reset the soot content and done a forced regen, not one puff of smoke that's how well this cleaned the DPF ( with a good flushing)NB!!! this is great for removing soot and oil, if you need to remove ash a diluted version of brick acid or an ash cleaner will be needed, there are many YouTube videos to show various methods, but for soot and oil you will not go wrong with this product.NOTE! before following the below instructions you must ensure the readings you are getting on your diagnostic are in fact correct, and all other issues have been ruled out/ fixed. take a copy of your readings before DPF removal or trying on vehicle cleaning. <------ IMPORTANT!!!instructionRemove DPFBlock off the intake end ( the flange coming from the inlet manifold) you are flushing the DPF out in the reverse direction to which way the exhaust flowsfill with the DPF cleaner and agitate then leave it over night minimum, it says 8 hours but 24 minimum, I left mine 48 hoursDrain the chemical in to a bucket if you wish to keep it,flush with hot water ( tap water hot) use a good few gallons and as the water runs through agitate the DPF turning it 12 to 6 and then 6 to 12 and shake it up and down as the water runs through, do this until the water running through the DPF begins to run clean ( it takes a while)leave to drain over nightfit back on to the vehiclewhen fitted and running the vehicle up you will note water running out of the exhaust as the engine runs, let the engine idle for around 30 mins, while letting the engine idle use a diagnostic to check the DPF pressure differential, please check what your vehicles Pressure differential ratio is ( it is around 6kpa for a transit on idle) I had 1-2 KPA which means the DPF is very clear. 100KPA on idle is a blocked DPF, on 2000 RPM after cleaning mine read 5KPAwhen you are satisfied it is in fact clear reset the soot content( running the engine on idle till hot and revving the engine while viewing the exhaust is an indication but the DPF psi differential is the best indication.do a forced regen when you are completely satisfied your vehicle now meets the criteria!after the regen erase all the faults and restart the vehicleNow the vehicle should no longer be in limp modeif you are unsure about anything you have read I suggest you seek professional help because doing a regen with a blocked DPF can seriously damage your engine.if you have ash blockage this product will not remove the ash, this product is great for removing oil and sootI will add some pictures later ### ⭐⭐⭐⭐⭐ Works a treat for 2011 Renault Scenic 1.5dci *by on Reviewed in the United Kingdom 3 December 2025* Used this on my 2011 Renault Grand Scenic 1.5 dci with K9K engine. Had clogged DPF. The DPF and CAT are in one unit but after a discussion with Wynn's this was found not to be an issue. Removed unit, easier than expected, and reverse filled the unit after removing the sensors. Had to plug Exhaust Manifold side. The Cleaning Fluid drips out of sensor hole when DPF full. Left for 8 hours, agitated every hour using exhaust flexy as bellows. Refitted unit. Soot went from 80g to 2g. 'Stop - Engine Failure Hazard ' error cleared itself. Excellent, saved a wad of cash. ## Frequently Bought Together - Wynn's Diesel Particulate Filter Cleaner - Heavy-Duty Cleaning for Severely Blocked DPFs - Restores Optimal Pressure Levels & Engine Performance - Biodegradable Formula - 5L - Redex DPF Cleaner Diesel, DPF Diesel Particulate Filter Cleaner To Clear Soot Blockages Quickly & Avoid Costly Repairs, Hassle-Free DPF Cleaner To Prevent Clogging & Reduce Emissions, 250ml - WYNNS Diesel EGR System Cleaner Aerosol - Powerful Jet Spray for Deep Cleaning - Dissolves Carbon, Tar & Varnish - Restores Engine Performance & Prevents Starting Issues - 150ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/422122552-wynns-off-car-diesel-particulate-filter-cleaner-heavy-duty-cleaning](https://www.desertcart.gr/products/422122552-wynns-off-car-diesel-particulate-filter-cleaner-heavy-duty-cleaning) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-07*
