There’s nothing better than seeing a freshly washed BMW glinting in the sun, except maybe sitting behind the wheel and feeling it roar to life. While you can take your car to a car wash once a week for a wash and wax, that can get expensive quickly — especially if you’re springing for the hand detailing. If you want to save a bit of money, how can you wash your BMW at home?

Clean It Often
You might not think you need to wash your BMW every week, but if you run into a situation where you end up with bird poop or tree sap on your paint job, you’ll want to break out the cleaning supplies. These substances are often acidic enough to burn right through the clear coat and paint, leaving your vehicle susceptible to rust.
The best thing you can do to maintain your BMW’s appearance is to wash it once a week. Of course, before you start breaking out the buckets and sponges, you’ll need to know what type of supplies to use.
Choose the Right Supplies
How many times did your dad let you help wash the car as a kid? The first thing you were sent to retrieve was probably the dish soap from the kitchen, because it made great suds and easily cut through road grease and grime.

Don’t make that mistake as an adult, though. Make sure you’re using soap and other supplies that are specifically designed for use on cars. That standard dish soap may work great on road grime, but it often contains abrasives to help you cut through stuck-on food while you’re cleaning dishes. These micro-abrasives can damage your car’s clear coat and paint.
Choose a soap or cleaning solvent specifically designed to work without harming car paint. You have a number of different industrial and consumer cleaners to choose from, all with one specific purpose in mind — keeping your BMW as clean as the day it rolled off the line.
Park in a Shady Spot
You might be tempted to park out in your driveway or street on a sunny day so you can soak up some Vitamin D while you’re washing your car, but we recommend against it. Yes, washing your car in direct sunlight sill causes the water to evaporate faster, but that quick evaporation will leave water spots and other unsightly marks on your exterior.

Instead of using the sun, wash your car in a nice shady spot and dry it off with soft microfiber towels to prevent the water from leaving spots or streaks on your finish. It might sound like an extra chore, but it can help preserve your exterior and prevent little things from becoming bigger problems in the long run.
Enjoy Your Hard Work
That’s all there is to it. As long as the water is beading up and rolling off your car, there’s no need for a new coat of wax, so all that’s left to do is sit back and enjoy all your hard work. Everybody loves the look of a freshly cleaned BMW, plus you get the satisfaction of a job well done.
