r/cardetailingtips

I bought an early 2010 lexus es350 which I love, but the problem is previous owner was a chain smoker. At the time I was like ok, how bad can it be?
Now I see it still can be bad. I tried to remove the grease and tar from the seats, speakers and let me tell you, it was bad! It was like you poured chocolate on speakers! Idk how the guy is still alive and don’t want to know how his lungs look like now but not my problem honestly.
I don’t want to mess up with electronics of the car but I saw some videos people clean the interior with wet brushes and detergent.
I also have a steam iron which I thought might help loosening up the grease from the fabric.
I’m also concerned how exactly I should clean the speakers inside the back. I don’t have enough knowledge to take parts out but at the same time I want to clean them so badly.

Give me all your tips please. I’m also a student so I can’t take it to a 200 dollar detailing shop or buy expensive products.

Thank you all!
