In other words you connect 8 hoses to the bottom of your water heater tank and spray through the filter all at once?

@@dannewtonful I think you are trying too hard to find fault. Hot water is not needed but if users prefer it good for them. High pressure is not recommenced. A flat hose nozzle works best as seen in the videos. Give it a try and see for your own. If you DPF has been heat cleaned it may be cracked? Cobra Clean will NOT crack a DPF.

Thank you, try it it works! Happy Holidays

Thank you, Spread the word!

Lol. Don't give out the secret of how you get a new engine. 😄

It may be partially clean and could damage/crack the ceramic DPF median

I think he means its been cleaned 8 times not at once.

Either way.. this method dosnt remove the ash content inside the ceramic traps... you need to cook it 1000f amd then use air pressure to get it all out.

@@ununius7436 the process of baking it is to burn the remaining soot. Then after the ash is blown out and the ash should be contained.

Cleaning 8 times was done on a bus, stop and go over 800,000 miles.

@@ununius7436 even cooking it at 1000 doesn't break down the ash, both methods only attack the soot, thats fine for cars that have clogged from missing a few regens or from faulty glow plugs If you want to clean an old dpf use this method first to remove as much soot as possible and then soak it in 1 part brick cleaner 3 parts water, that will dissolve the ash extremely quickly whilst having little to no effect on the stainless, platinum or cladding, just don't soak it for too long, you'll know its working if the liquid coming from it is stained red as the ash is red and the soot is black I hope this helps you clean it from home as it seems extremely difficult to find information on the dpf even from garages, however theres many people cashing in big on flushing a single solution through or running a forced regen that will only last a few months edit: make sure you use either this method or a heavy degreaser such as caustic soda drain unblocker first, as the acid solution has piratically no effect on the oil/soot which can then protect the ash deposits ( and make sure the drain unblocker remains under 100 degrees c as beyond that point it will react with the silica)

Melts Carbon on DOC's and EGR Valves, not damage.

Jun The solution after soaking the DPF should be rinsed out on a wash rack with a filter. The Cobra Clean after it is used up after a few cleanings can be disposed of with waste oil. Cobra Clean is a Biodegradable Non Acidic Non Toxic solution.

You are advised to rinse your DPF in a wash rack that has a filter. Most commercial facilities have a filter on them. DO NOT use a pressure washer. Some trap it and recycle it with their oil.

You can dispose of the used Cobra Clean with waste oil. Note just because it is black does not mean it is spent. if you set it aside covered the soot sinks to the nottom. 15 gal can clean 2 sometimes 3 DPF's.

It is best to rinse in a filtered wash rack in a commercial garage. If not avail some use a homemade filter to trap the carbon. The COBRA CLEAN itsel is Biodegradable.

Down the drain..

Cracked DPF need to be replaced, heat cleaning or pressure washing could damage a filter.

Why? I really don't understand.

This is why it’s on KZfaq… to make it accessible for DIY’ers. I don’t think the professionals would use these methods as they have a much more complex and functional set up with all the right equipment. This is a layman’s video so the whole point is not paying a dime to do the job that needs done.

@@jobbiejew Commercial and municipal governments are the primary user of Cobra Clean. Some even own a FSX professional oven and stopped because Cobra Clean dis a better job with no damage.

Soot is burned out, I would not use water because it with cause ash to turn into concreate.

Your call heating one will dmage it. Cobra Clean melts the Ash.

Richard sorry to hear that go to ECOFuelMax.com and use the phone on that site. I am a warehouse distributor not a salesperson.

SLAWEK The Cobra Clean is a Biodegradable Non Toxic, Non Acidic cleaning solution that melt5s Carbon. When rinsing the soot out it is advised to trap the soot in a filter on the wash rack or drain filter. Good Luck & save $$

Richard thank you for your question/response. For a standard Truck DPF that is approx 14" tall and 14" in circumference you will need 13-14 gallons as can be seen in the You Tube videos. a 15 gallon container should be able to clean 2-3 DPF's so do not dispose of the used Cobra Clean. Note, Do NOT let it FREEZE. To see more videos go to ECOFuelMax.com in the right link column click on Cobra Clean. detailed instructions are there. You can always call me 561-860-6888

A typical DPF needs 15 gallons.

Sky, it will not work and the sensors may shut your vehicle down.

Flow. You can also measure it, the flow. To see if it is to restricted

When its cracked it TOAST!!!! If you have to perform a forced regeneration on any DPF system you have something WRONG!! Most likely its Upstream Failure from an over fueling injector, cracked injector cup, leaking EGR cooler, burning engine oil, failed turbo, ECT. You have to address the failure FIRST before replacing the DPF or you will this same issue agai . If the aftertreatment is performing like it should per OEM specs you will need to remove and clean it every 300,000 miles.

Cracked will not perform the same way and your NOX conversion and EGR pressure will change and truck will debate eventually.. also may not reach proper regeneration temperatures

When a DPF is cracked replace it. A cracked clean DPF will not work properly. In the future using Cobra Clean will extend the life of your DPF, heat kills it.

Thank you for your comment. Sorry to say thousands of DPF's have been successfully cleaned without heat. Heat damages a DPF. The Cobra Clean is 100% biodegradable Non Acidic, Non Caustic. The KZfaq DPF video you commented on was one check out the others on KZfaq click on CobraCleanUSA and have fun. If you prefer heat that's your call but beware you may have to replace your DPF after 2-3 cleanings with heat (+/-$2300). Order 15 gallons and test it, you will be a believer. Cobra Clean costs +/- 75% less. Have a GREAT Day!

False, Cobra Clean will melt the carbon

yes

Astra: DPFs should be dry for best results. Some use a wetvac, some a air hose and others put it in the sun if avail. A diesel motor exhaust gets to 1100-1200 degrees so a slightly damp dpf will dry. A wet one could restrict air flow, not reccommended.

every 100k kilometers

Monthly if your lucky

It depends on your duty cycle.. if you idle alot of the time you will need to do it more often like yearly

When it gets dirty. depends on use. some do a 6 month service thats for stop and go vehicles. Check out the ECOFuellMax to reduce particulates.

No it is reccommended to filter the waste particles.

Absolutely, the key is soaking it for 24 hours and melting the Carbon Particulates.

After soaking spray with water either way is OK.

Bake it 2-3 time and replace it. Some after cleaning with Cobra Clean pressure test it and yes it works as good if not better than heat, no damage. One Florida Municipality that has a FSX machine washes, rinses and then uses the air to dry and pressure test it. If it didn't work why would they stop using the $45k cleaning machine.

Yes it is recommended that a filtered drain be used to trap the soot. Commercial users who are 95%+ rinse and trap the soot.

Yes, a cleaned filter should be rinsed in a wash rack that has a filter.

Backyard mechanic: no, we just rinse it out with water in a ditch behind the shop and hope nobody notices. Lol 😁

yes, it is reccommended to filter the soot.

Ununius By using Cobra Clean a Non Toxic Non Acidic cleaner that melts carbon you will not need to bake a DPF at 1800 degrees. By not using heat a DPF can be cleaned more than the 2-3 times using heat. Testing has shown a superior cleaning verses baking. Soak, Rinse, Dry reinstall and off you go. Thousands have tried it and swear by it. It is hard to comment unless you tried it yourself. Good Luck.

Here is another answer. Baking a DPF will damage it aftew a few cleaning. Replacement is +/-$3,000. Your call don't knock it until you try it.

Any design suggestions for creating a better dying system? I was thinking they could increase and further control the spray nozzle with something 3D printed, something that sprays the entire flow through as opposed to spot rinsing. They could also add a frac tank to let heavy carbon sediment drop out and re-circulate the water and or solution.

@@dannewtonful Use a flat nozzle sprayer so you won't get wet. I have tried many different variations, the flat head hose nozzle works best. Yes it takes +/-10 minutes per filter to rinse, that's the hard part.

Devin Don't knock it until you try it. Heat 1,800 degrees is proven to damage a DPF
