Any suggestions? Mine is very soiled.

 

Degreaser such as Purple Power or Simple Green and a pressure washer ... after they've been removed of course.

Search the web for Youtube videos as there are some very good ideas out there.

But the above recommendation, I've found, works the best.

 

pressure washer needed? or will a regular hose do the trick?

 

you could use a towel and same results, pressure washer less time, you will have to remove the seat belts. I have my car in pieces righ now working on detailing everything inside. Simply Green to the rescue

 

Degreaser and All purpose cleaner agitate with a soft bristle brush, tooth brush will do and wipe it clean.
