First; make sure it’s a warm enough day so that the water isn’t going to freeze when it touches the cold metal of the vehicle. Always wet the vehicle down first. Take a hose and run clear water over the whole car. (Make sure your windows are up). Take a bucket and put some specific car washing detergent/ shampoo in it, then add the warm water to the top of the bucket. You should have lots of suds now!
Second; Take an old soft rag and without wringing it out, start on the roof and use plenty of the soapy mixture. Now do ½ of your car top to bottom. Rinse this off well with clear water from the hosepipe. Now do the other ½ of the car.
Third; After it has been completely soaped and rinsed, take a clean chamois cloth and start drying it off, wringing out the chamois frequently. Do this all over the vehicle until it is completely dried. There may be some spots where water will continue to dribble down, like from the mirror or back brake lights.
Lastly; You may have to go around the car a second time to ensure that there are no drip spots where it has run down or wipe it down with a shammy or microfiber cloth.
At this point you could take some spray wax and lightly spray a small section of your car at a time and rub this into your paint using a clean soft cloth such as a microfiber cloth or flannel material, until you have a smooth, even and shiny finish.
You should be able to throw the cloth across the roof of your car and it will slide to the other side…
That’s when you will know that all the spray on wax has been rubbed off and there will be no visible signs of it left on your car…
By keeping your car clean and waxed this way, it will preserve the paint longer, keep it from rusting sooner, and will make you very proud to show off your vehicle as you drive it to your destinations and by taking care of your car it also shows that you have respect for what you are putting your hard-earned money into.
