Tidy up. It might sound pretty straightforward, but making sure you’ve got a tidy car will make everything a lot easier. Declutter, empty the bins, and remove any rubbish from the car’s floor or the backseats. Also be sure to take as much out of the boot as possible – it’ll make it look bigger.

Windows. Windows are the best place to start as they are already half done – you’ll have already cleaned the exterior so any dirt or smear marks on the inside will be easy to spot. Use car window cleaner rather than household and use a slightly damp micro fibre cloth to wipe the windows down.

Plastics. Wipe down the dashboard and other plastic interiors (such as cup holders and the glove box) with a general purpose cleaner. Be sure to spray the product onto the cloth and not the plastic – you don’t want liquid creeping its way down cracks and getting near electronic.
 
Vacuum. Get a stiff brush and rub the whole carpet rigorously with it. This will help bring up all the dirt. Move the driver and passenger seat chairs all the way to the front, and vacuum the back of the car, then push them all the way to the back and do the front.
 
Nooks and crannies. Use a paint brush to clean smaller areas, like in between air vents.

Upholstery. Use a specialist car upholstery spray and spray a fine mist over the seats. Leave for a moment then wipe. You can reuse the micro fibre cloths again; just ensure they’ve been rinsed and dried.

Mats. Cleaning your mats is probably the most tiring part of the process – but it’s also the last. There’s no quick fix way to cleaning your mats, just hang them on the line, and beat them with a stiff brush until all the dust and dirt has come out. You’ll feel like a housewife from the 60s, but it’ll be worth it. Don’t put them in the washing machine, as this may clog your pipes. And don’t stand down wind.
