Autoglym Hi-Tech Interior Microfibre

Can be used to remove dust or in combination with interior cleaners and dressings.
Nothing will replace the vacuum cleaner for dust shifting capabilities, but this cloth comes in a close second, and at 40 x 40cm it is small enough to fit in your glove box.
It is also perfect for de-misting your windscreen on cold mornings if your heater is struggling, and removing fingerprints from displays and navigation systems.
