Highly effective cleaning and neutralization fluid required after cleaning the diesel particulate filter with Pro-Line Diesel Particulate Filter Cleaner. Pro-Line Diesel Particulate Filter Purge washes out the soot dissolved by the cleaner and distributes it in the diesel particulate filter so that it can be burned off with normal regeneration. The cleaner is neutralized by the Purge. This product is also used with the diesel particulate filter installed. Problems with clogged diesel particulate filters mostly affect vehicles driven short distances. That means the interval for cleaning with Pro-Line Diesel Particulate Filter Cleaner and Purge is very much dependent on the use of the vehicle. Regular cleaning can help reduce running costs. No more need for the usual and costly business of replacing the diesel particulate filter.
Areas of application
For rinsing the diesel particulate filter (DPF / FAP) in installed condition after cleaning with Pro-Line Diesel Particulate Filter Cleaner.
Application
Cleaning is performed with the DPF Pressure Cup Spray Gun (part no. 7946) and the specially developed DPF Gun with 5 spray probes (part no. 7945). Depending on the type of vehicle, access to the diesel particulate filter is to be established. On most vehicles, the temperature or pressure sensor of the diesel particulate filter must be removed for this. Note: The temperature of the particulate filter during cleaning should be less than 40 °C. In some vehicles the diesel particulate filter is located near the exhaust manifold or in some cases the turbocharger rather than on the underbody. For safety reasons, extreme care must be taken when cleaning these vehicles to ensure that no cleaning or flushing fluid gets into the combustion chamber through an exhaust valve that has been left open. The appropriate Pro-Line Spray Probe for the type of vehicle is introduced into the particulate filter through the opening that is created. The total amount of ProLine Diesel Particulate Filter Cleaner cleaning fluid (1 l) is sprayed directly onto the surface of the particulate filter in several intervals of 5 - 10 seconds with a break of 5 - 10 seconds in each case at an operating pressure of 6 - 8 bar. In order to coat the entire surface with Pro-Line Diesel Particulate Filter Cleaner to the greatest possible extent, the probe must be turned and moved back and forth when cleaning. Wait approx. 15 minutes to allow the cleaner to take effect. The particulate filter is then rinsed with the total amount of flushing fluid (500 ml) with Pro-Line Diesel Particulate Filter Purge. Processing is likewise performed with the DPF Pressure Cup Spray Gun (part no. 7946) at the same intervals as for the cleaning fluid. The cleaning process dissolves the soot enough and distributes it in the particulate filter so that it can be burned off with normal regeneration. After the sensor has been reinstalled, the service operation or the workshop must initiate a regeneration according to the manufacturer’s specifications. Attention: Refer to the safety data sheet for the protective measures to be taken when handling the product.
Comment
CAUTION: Depressurize After applying pressure vessel and completely. Gun should not be stored with material in the container.

Holy Grail Moisturizer for Rosacea
Style: Restorative Protective Cream-3.3 Fl Oz
In seeing so many negative reviews I felt compelled to weigh in as this is my favorite moisturizer. I have very dry, menopausal skin. Additionally, I have rosacea which seems to have been a nice gift from said menopause (you can only laugh, right?). It's very common for those of us in our 50's to have a compromised skin barrier and when an issue like rosacea is present, even more so. Because of all this my skin is very intolerant to most moisturizers and nearly all actives (over the last few years I've had to discontinue my retinols and chemical exfoliators). While ingredients like ALA's, petrolatum, mineral oil, parafin/bees wax, and lanolin are well tolerated and known to be quite soothing, they don't hydrate very well as they are more occlusive than moisturizing. Enter this product. Magically, it does both! It's marketed as a protective cream, which again implies occlusive, but it penetrates like no other. Gone is the tight, dry feeling that persisted even when I had a heavy layer of product on my skin (my previous moisturizer was Eucerin Original Healing Cream -- which still has its uses -- because it was the only thing I could put on my skin outside of squalane oil during a flare). Now, no topical can cure rosacea. However, the right product can calm the skin, repair the damaged lipid barrier, and improve its appearance. This moisturizer does just that and it's become my holy grail. Since starting this I've also added in the Cicalfate Serum which has only aided in repairing my skin. Another Avene product that works great for me is the XeraCalm Balm which helps with itching. I use all three of these daily and they've really helped fix the secondary issues that come with rosacea. As for the complaints about it being greasy or too heavy. I can see this not working for people with normal or oily skin (or perhaps only in moderation). But my skin loves the heavier weight and because one of the ways I soothe a flare is to keep a tiny mister bottle on hand and repeatedly spray my face so I have to guard against the drying effects of evaporation. These products are so lipid heavy that I can wet my face all day long without worrying about that, though I do reapply throughout the day. As for the watery consistency issue, I haven't had that problem but it does caution on the packaging not to expose the product to temperatures below 41 degrees F (5 C). I suspect that if it gets too cold either because of the weather or because of whatever warehouse it sat in during transit it will separate. Maybe open the package and before squeezing some out look to see if it has split and then shake it up/message the tube. So, if you have skin like mine don't hesitate to try this product. I'm leaving this absurdly long review for my struggling brothers and sisters out there with rosacea in hopes that it provides some relief! Happy moisturizing, internet strangers. ;)

Possible solution to seperation
Style: Restorative Protective Cream-1.3 Fl Oz
I love this product so much, but, like everyone else the water HEAVILY separated. A lot of water just shot out immediately and as i've used the cream it has felt more and more thick bc of that, shaking the tube or not. POSSIBLE SOLUTION: I actually think the company could salvage this problem by upgrading packaging to a Cosmetic JAR and then customers could take a toothpick and stir if separation has occurred by the time of purchase. I hope to try this with my next tube, just toothpaste squeezed everything out into a nice cosmetic jar and stir the water back into the product. This is such a simple solution that could really solve the product waste. This refreshes my skin, doesn't break me out, and is lovely. I break out so easily, and being middle aged my skin really requires a dense help with moisture. <3

Ordered in spring/summer and it arrived separated too BUT...
Style: Restorative Protective Cream-1.3 Fl Oz
Ok, So I heard great things about this cream and decided to order. I ordered on May 28th and I live on the Gulf Coast of Texas and it is in the low 90s right now. I was worried mine would arrived separated like many others claimed to have gotten theirs, and sadly it did. Warm weather or not, blue water shot out of the tube the minute I squeezed it. Luckily, I read Mia P's review and submerged my tube in warm water (hot water actually straight out of my instant hot water faucet). I left it for about 5 minutes then shook it vigoroously. It seemed to help but was still a bit wonky so I repeated the process again and success! My tube is totally fine now and comes out in a thick, rich, emollient cream as it is supposed to. I will update my review after I use it more but so far I love the way it feels on the skin. It is very thick but spreads nicely and completely absorbs into the skin and leaves no greasy residue which is a big deal because I have oily skin. I purchased this to help with my Retin A uglies (I actually am using Musely with .05% tretinoin) and am hoping it helps with the redness and peeling I am having. I will update my review once I've used it for a while but wanted to post this review as I saw so many people complaining about the separating and just thought I'd mention that you can fix this issue if you have it (and there is a good likely hood that you will). Update: I've been using this for a week now and I am absolutely in love with this cream! It is the most hydrating and healing cream I've ever used. Usually, thicker face creams like this would cause issues for me with acne or clogged pores as I do have oily skin that can break out if I use products with occlusive ingredients, but this one does not. In fact, my skin has never looked better! This is a must-have if you are using Retin-A/Tretinoin and going through the red/peely phase with your skin. The separation that occurred when I first received it has not been a problem and the cream is staying thick and free from any strange liquidy issues after I put it in hot water as mentioned in the first part of my review.
