Salt and Sand
Salt air and sand is great when you’re enjoying the beach. They can, however, have an adverse effect on your vehicle. Sand can build up under your vehicle and also can hold moisture, which accelerates rust and corrosion. Salt air and sand can create minute scratches in your vehicle’s clear coat finish and paint that can lead to small rust spots.
Rock salt and sand is applied to road surfaces to melt ice and assist with traction during snow or icy conditions. While this is a great benefit for traction, the salt residue that gets on your vehicle (mostly on the under carriage, the bottom of your vehicle, and on the vehicle’s body) accelerates rust and corrosion. Sand also can build up under your vehicle, and since it can hold moisture, it also accelerates rust and corrosion.
Rustproofing your vehicle will substantially help prevent the start of rust and corrosion.
Apply a good quality wax to the finish of your vehicle. This will help protect against the salt and sand effects.
When driving on roads that have been treated with salt or sand, wash your vehicle at least every two weeks. This may appear excessive, especially since salt and sand will get on your vehicle just from driving home from the car wash. However, this will ensure that salt and sand does not build up on your vehicle. Be sure to get the underside clean.
If you drive near an ocean (or any body of salt water), wash your vehicle at least every two weeks. This will ensure that sand and the salt in the air will not build up on your vehicle.
If left neglected, rust and corrosion can eat away at your vehicle and may affect safe operation. Areas commonly affected by rust and corrosion include: brake lines, fuel tank, fuel lines, frame rails and suspension parts, floor boards, and lower body panels (the lower portion of door edges and fenders).
