I have been catching up on some much needed maintenance lately (1999 Intrepid 2.7. replace leaking water outlet, burned out lights, various pet peeve type fixes), and decided to do a little detail cleaning since i had some extra time today. The cleaning actually started when i reached under the flase floor in the trunk to try to locate a lost tool and felt water, deep water, but that's another story for another thread. I ended up having to go to the car wash to use their vacuum to suck the water out, and decided to use the high pressure water. I have been noticing my door jambs and truck jamb lately, and how grimy they have become. I decided to get them clean. While at the car wash i simply opened my doors and used the pressurized water to spray off the jambs, being careful to minimize the amount of water getting into the cabin of course, and i was completely amazed at how well it worked. The jambs came nearly 100% clean with just the use of pressure sprayer. When i say clean, i mean i could rub all around the jambs with a fresh white rag, and the rag would come out still fresh and white. Basically, all of the jambs on the car look freshly painted. There was a little water in the cabin, but after the first door i got smart and covered up the power switches with rags just to be sure they wouldn't corrode or short, and i just wiped up the rest of the water with the rags. It was simple, cost me about 2 dollars, took me about five minutes, and now the jambs look like i spent all day cleaning them. I also had to remove the tail lamp assemblies to remedy some burned bulbs, and i decided to clean the bumper cover and hidden surfaces of the lamp assemblies while i had them out, and they turned out great, look like brand new. After the unexpected success, i decided to go back to the car wash and spray the jamb surfaces of the actual doors and truck lid, and i got the same result as with the body jambs. This process is completely worth your time and money and effort! I feel much better about my car now. It doesn't even look like the same car... that's how big of a difference it made!
