Welcome and thanks for stopping by!
There is a
thread here that has some excellent tips on it. The PDF file posted by Vlad is there but if I just click on it, it eventually says the file is corrupt. BUT if you right click and do a "save as" to save it locally, I can open it after it's on my drive. Go figure.....
Just my two cents worth to keep it showroom (with a bit of labor):
1. Never use an automatic car wash that touches the car.
2. Touchless car washes are OK as long as you don't have a convertible.
3. Follow Vlad's recommendation for TWO hand wash buckets - a wash bucket and a rinse bucket. Get the dirt out of your wash rag/sponge before soaping up again.
Wax? I use Meguiar's Gold three 3 step. But this is always a great topic of debate - which wax is best????
