With the cold winter weather effectively putting paid to those events, taking the roof bars off and packing them away may sound obvious, but in reality complacency often dictates they’ll be left on. And that can prove costly.
Figures from the RAC and compiled by the Energy Saving Trust, show the wind resistance they create can cause a car to use more fuel through the ‘drag’ effect. It is estimated an empty roof rack adds around 16 per cent drag when driving at the national speed limit. At the same speed, a roof top box adds close on 40 per cent making a vehicle less fuel efficient.
By simply taking it off makes sense, and so does a simple prep for their winter hibernation to ensure they will be in full working order come the spring. And that’s where the combination of WD-40 Specialist® Degreaser and WD-40 Specialist® Spray Grease come into their own.
WD-40 Specialist® Degreaser is perfect for cleaning all the residual grease off the internal mechanism. A simple but liberal spray of solution on all moving parts and then a wipe off will inevitably clean all old lubricant that will eventually prove problematic. Once clean, a careful spray of WD-40 Specialist® Spray Grease will prepare the roof rack for its winter hibernation and ensure it will be problem free when needed in the new year.
