Hello! I am the proud new co-owner of a 1998 260 Mackinaw and looking for some guidance on the infamous Monkey Fir aka the 70's berber carpet on the walls....how does one best go about cleaning this? At first go, it was emitting what I thought was salt, but I came to realize I think its just "crumbling". I then attempted a hard brush with some cleaning solution on it and that caused it to start to pull up the glue from the wall. My next thought is to go to a hand held steamer....looking for anyone with experience with this. Thanks in advance!
