A little elbow grease waxing your car can make all the difference in helping it through the cold weather. So invest in Comma Top Gloss polish (£4.99), or if your paint is new, Turtle Wax Platinum Extra Gloss (£9.99), plus Turtle Wax Black In A Flash (£3.69) for plastic. Keep rubber supple with Autoglym Vinyl & Rubber Care (£5.99).
