If your car is beginning to wilt in the recent rain, why not treat it with these products I found in Mongkok. They could add some gleam to a grey day. Unicon Fabric Seat & Mat Cleaner, $55 Car interiors are made of so many different materials, but it's nice to know you can buy one product for most of these surfaces. This product can also be used on plastic and vinyl seats, dashboard and door panels. The foamy substance easily removes stains with the brush inside the box; while a piece of foam cleans plastic parts. The product is said to kill germs, too, so no wonder it smells rather like cough syrup. Soft 99 Room Multi Cleaner for Cars, $78 This product is said to clean all interior surfaces and, thanks to its green-tea extract, remove bad smells, which is useful in this musty damp. The product's soft brush worked on my carpet, and didn't leave a smell, as promised. STP Son of a Gun One Step Tire Care, $38 The American brand draws on the name of Nascar driver Richard Petty, but the product works just like any other tyre foam: just spray on the tyre walls and the stuff cleans, protects and shines. It works fine. The tyres are blackened with a moist-look in seconds. But the effect won't make you scream: 'Son of a gun!' Rain X Fast Wax $82 (473ml) The first thing we do with car waxes is smell them, and one sniff is enough to tell that the Fast Wax is a winner. The strong smell of coconut gives your car a whiff of the tropics, of beaches, sun and sand. Rain X Fast Wax claims to be easier to buff off than conventional waxes, and it's true. It gives the car a smooth surface and hides swirl mark, as premium waxes do. It can also be applied when the car is still wet. Rain X Wash & Wax, $69 (591ml) Look closely at this car wash, and you'll see there are hundreds of tiny bubbles suspended in the solution. It looks rather like sago sweet soup dessert. These are Carnauba wax beads that will dissolve under a running hose. As its name suggests, the product removes dirt and leaves a waxed feel. After use, the car body is noticeably smoother. If only the product had an aroma. Meguiar's Gold Class Wash Sponge ($28) Meguiar's should earn an award for crafty marketing with this product. Sponges are sponges, but the American manufacturer says the Gold Class Wash Sponge's fabric structure is stronger than ordinary squeezers in order to withstand the sharp edges of emblems and the likes. The Gold Class Wash Sponge is the right size and shape, user-friendly, and worth the money. It didn't tear when I used it on the exhaust pipes and mud flaps.
