Sand can often be very awkward and time consuming to remove from carpets and mats. Once trodden in it works it’s way to the bottom of the fibres of the upholstery and will remain there until it is dealt with properly.
The first step to effectively removing sand is to take out all of the mats, then one by one beat them from the underside with a suitable implement to release as much loose sand as possible and to help bring the ingrained sand up to the surface. You should spend a little time doing this as the more sand you can remove now the better. Try to do this in a secluded area away from your car to prevent the sand and any other material from blowing back into, or onto your car.
The second step is to lay the mats down and use a stiff bristled upholstery or detailing brush to agitate them. This will further help to release any ingrained particles from the fibres, lifting them up to the surface. Work the brush in alternate directions and ensure all areas are sufficiently agitated.
After brushing the mats the third step is to give them a thorough vacuum. A crevice tool type attachment should be used as this provides the best possible suction. Again, vacuum the mats in alternate directions and continue to do so until all the sand has been removed. If initially, you sufficiently beat them then vacuuming should not keep pulling up sand, if it does however you should go back to the first step and repeat the process.
If the carpets of your car have been affected with sand deposits they too should be dealt with in a similar manner. Obviously you cannot beat the carpets like you can the mats, but instead you can simply use your hands to pat down on the surface. The vibrations of this patting down will help the bring ingrained sand particles up to the surface which can then further be agitated with the brush and thoroughly vacuumed up.
One thing you should not do when attempting to clean up sand is to wet the area with a cleaning product for example because the fluid will encapsulate and soak the sand particles down even deeper into the fibres and it will be even harder to remove.
Sand is one of the most awkward things to clean up and remove from the interior of a car and it can take a little time and persistence to successfully remove heavily affected areas but if you follow this method it will help to speed up the process and achieve successful results.
