I have a 2011 CR-V 4WD that has a rebuilt title. The liftgate was replaced. Guessing by the condition of the interior, the prior owner parked it in a field somewhere in the weather for awhile atleast and it sat the entire time missing the liftgate. The seats are all stained which I am currently working on but there is small pieces of dead grass embedded into the carpet upholstry that I have never had much luck getting out. Another thing that bugs me is the exterior door handle assembly's are caked full of dirty on the inside. They look clean outside but there are always streaks of dirt coming down the door from the handles. See pics. The interior pics are not the best but it is just under the seat but it has looked like that for the whole year and a half I have owned it. Every creavous is filthy, the engine is coved in a layer of dust, the vents are filled with dust, ect...Im on SSD and complete detail is expensive. Any helpful tips on how I can get this car cleaned up in a DIY fashion? Thanks.
