Interiors are graded by material, not by area, because the same cleaner that is correct on a rubber floor mat will strip the finish off coated leather. Work top down, vacuum before anything wet, and test any new chemistry on a hidden section first — a door pocket, under a seat.
The single most common interior mistake is over-wetting. Fabric and foam hold water, water holds odour, and a seat that was cleaned enthusiastically on Tuesday smells on Thursday.
