Like the title says.

I picked up a 96 civic recently and interior cleaners aren’t working as well as I need them to. Anyone have any tips and tricks they can share?

 

Pick up a steamer. I have a $100 unit I picked up many years back and it works great for this. For really dirty interiors, I steam the surface to warm it up, then spray APC on it (I like Optimum APC diluted at 1:10 for usual; 4:10 for heavy duty), agitate with a brush, then hit with steam again, then wipe clean with a microfiber. If really bad you may need to do this a couple times.

Some people like to use a magic eraser but I would avoid that unless really necessary. It is pretty abrasive.
