So your car is squeaky clean, waxed and buffed to the max. \u00a0Your wheels are clean enough to eat off, as is your engine bay.\u00a0You revel in the shine and gloss of your beautiful ride. \u00a0You open the door to jump inside and take a drive\u2026<\/p>\n

As you sit down, you notice an obscure area, visible only in a flash. \u00a0You look again; it\u2019s your doorjamb looking straight back at you. \u00a0It is dark, uninviting, and elusive. \u00a0As you disregard the neglected doorjamb and start to close the door, a ray of light shines through and lights up the dark crevice: \u00a0Oh my Goodness!<\/span><\/p>\n

Doorjambs serve many purposes. First, they act as a seal between the door and the body, shielding the elements, wind, and temperatures from the cabin. Dirt many times accumulates in the jambs by design and is left to bake and freeze under sun and snow. \u00a0 Even more, these areas usually never get rinsed off when washed. \u00a0Doorjambs also are the housings to the structures that allow the door to open and close; one or more hinges, door strikers, guides and knobs, each smothered in grease. Vehicle manufacturers and dealers slop up the doorjambs to prevent customer complaints about squeaks and noises from opening and closing the door. \u00a0Most people will never look twice at the doorjambs, but that is not the case with a car enthusiast or hobbyist detailer, or you probably would not be on this website this right now.<\/span><\/p>\n

Why clean your doorjambs? \u00a0It makes it easier to clean in the future. It makes the car look better maintained, and cleaner overall. \u00a0We really hate seeing filth on our cars any time we get in or out. \u00a0We’ve wondered if passengers ever notice how bad they are (OK, were). \u00a0But the best thing about cleaning your doorjambs is you will greatly decrease the risk of rust forming around your doors, and gives you a chance to do an early diagnostics of any problem areas arising. \u00a0Remember; the dirt, grime, grease, and moisture accumulate in the jambs and can stay there for years. \u00a0If your vehicle\u2019s roof \u201cgutters\u201d drains into the doorjambs, you have a perfect place for farming rust. This is especially important for domestic pick-up trucks. \u00a0Once clean and waxed, no dirt will ever last there, and keeping them clean will be a matter of a quick wipe with a Quick Detailer <\/a>after every other wash or so.<\/span><\/p>\n

This will also work for trunk jambs, engine bay jambs, behind the fuel door, etc.<\/span><\/p>\n

So how do we clean them? In a simple word: patience.<\/p>\n

Cleaning your doorjambs will take some effort, and crouching down or lying on the floor for the harder to reach areas. \u00a0This is nothing complicated or difficult so anyone can do it. \u00a0Set aside about 2 hours in the shade on a cool car. \u00a0We prefer to do the jambs before washing the car<\/a>.<\/span><\/p>\n

We will refer to all parts of the door to body interface as the \u201cjamb\u201d. \u00a0This includes the door edges, underneath, the A-pillar jamb area and the B-pillar jamb area. \u00a0If a 4-door, then the C-pillar jamb areas and rear door edge too. \u00a0The dirtiest areas are typically underneath the doors, so pay special attention there.<\/span><\/p>\n

\"Degreaser,<\/p>\n

You will need a few smaller brushes with medium to long bristles, an old toothbrush or two, a few general purpose microfiber towels<\/a>, and some cleaners. \u00a0To start out with, Meguiar\u2019s APC <\/a>at 4:1 does a good job of loosening the grime, but any cleaner may take more than one application to get the jambs sparkling (you can also do the jambs little by little with each time you wash). You will also need a spray bottle <\/a>filled with warm water, or if possible, some Optimum No-Rinse <\/a>mix, to flush the loosened grime and chemicals from the finish.<\/span><\/p>\n

Remember this is a painted area and therefore deserves special care in the same way as the rest of your finish. \u00a0Brushes must be soft as to not cause marring or swirls in the jambs. \u00a0As you can imagine, polishing out swirls from the doorjambs is almost impossible in certain areas. \u00a0Also, do not let the cleaners dry upon the surface. \u00a0Start with one door and stick to it until you can rinse it off. \u00a0Don\u2019t try to do too much too quick and spray all doors with APC, then have to hurry up to keep it from drying.<\/span><\/p>\n

Once you have on your nitrile gloves, spray the APC directly into the doorjamb. \u00a0Don\u2019t be shy! \u00a0Make sure to keep the spray from falling on your interior surfaces (it will clean away any dressings and can stain interior plastic at this strong of a concentration). \u00a0Let dwell for 30 seconds, and start to agitate with the brushes. \u00a0Use the toothbrush for hidden areas, and where components bolt to the body (like the hinges, etc.). \u00a0Make sure to brush off the rubber casing that carries your electrical connections from the body into the door. \u00a0Try not to spray APC into the door latch itself. Instead, spray the brush lightly, brush off, and wipe the rest away leaving the latch mechanism clean and dry.<\/span><\/p>\n

Focusing on the tricky areas. \u00a0Make sure you clean around and underneath the rubber seals as good as possible. \u00a0Take your time and repeat the process a few times. \u00a0Get into the folds of the door seals. \u00a0When wiping, get the towel up into the seal crevice. \u00a0If it turns dirty, repeat the cleaning. \u00a0This is the stuff that will stay there forever if you don\u2019t get it\u00a0 now, and if it contacts metal, can cause the doors to rust prematurely.<\/p>\n

As you brush you will notice the grime that is coming off. \u00a0Keep spraying new APC to clean further, but remember to rinse off the APC every once in awhile, before it dries on the surface. \u00a0Once clean enough, spray off excess with your water bottle or Optimum No-Rinse mix. \u00a0Try to use the stream pattern (open the nozzle tip a bit more) and get water to force the grime and APC out of the crevices. \u00a0Alternatively, and only for the very brave or Jeep owners, use your pressure hose and spray off the doorjamb (this WILL get your interior very wet and can fry your electronics, damage your leather, etc.). \u00a0Once rinsed, wipe off the excess moisture and any streaks of grease still present.<\/span><\/p>\n

Once dry, use a Quick Detailer <\/a>or Spray Wax<\/a> and spray down the jambs. \u00a0Wipe off and buff with a soft microfiber towel <\/a>to reveal a slick, clean doorjamb.<\/span><\/p>\n

Options:<\/p>\n

If the grime is really tough, use a stronger yet\u00a0safe cleaner like P21S Total Auto Wash<\/a>.\u00a0\u00a0Just be cautious when using other\u00a0very strong cleaners and strong ratios though because you could potentially run the risk of damaging something you do not intend to.<\/span><\/p>\n

While washing the exterior of a vehicle with a pressure washer, open and slightly close the door so it is latched but not fully closed (you would need to pull the handle to unlatch or bump the door again to shut it). \u00a0Spray into the jamb with a fan spray to use the water\u2019s velocity to yank out grime and dirt. \u00a0This can get your interior very wet if the seals are not contacting the frame, but in most cars it will only get slightly damp. \u00a0The high-pressure water is a very powerful tool for getting really caked-in stuff off.<\/span><\/p>\n

You can hand polish the larger, open areas of the jamb, quite easily with some M205<\/a>, or Klasse AIO <\/a>on a foam applicator<\/a>. \u00a0Just like the exterior of the car: the more polished the better your results will look.<\/span><\/p>\n

Remember that with no grease anywhere, your doors will squeak. I found a clear grease lubricant packaged in a syringe at my local auto parts store that permits me to administer lube exactly where I want it, while keeping it off the visible areas.<\/span><\/p>\n
