a best effort is done to clean its bay.
i put my hand , fingers, cloth, brush whereever i could reach inside the bay. i cleaned all the grease, black spots, and found some welding downside which was giving impression of grease.
now i want to go for a thorogh service of it, but the rust down there is scaring me, coz in car wash water may get inside the car down the carpet and will cause more rust.
SUGGEStions requiredddd !!!!!!!!
