i use Griot's Interior Cleaner for cleaning cloths seats and carpeting in general.
if ur ride is a dd i would scotchguard it now (if that's cloth, not leather) and just follow up with this. spray into door panel directly or regular hand towel and scrub gently. follow up with a warm water wringed towel
