Ok dont laugh please, how to clean the car?

where do you buy your car care stuff in Costa Rica?

The most important thing in my opinion is to buy the best towels you can have shipped to you. Don't use any towels from autostores or big discount department stores. Cheap towels will ruin your paint. I buy my towels by the 12 pack from Poorboysworld.com (mega towel) or from Detailcity.com. They sell basically the same towel it just comes in different colors. The towel has silk binding which is VERY IMPORTANT. Loose or unlooped threads are bad for paint.

The 2nd most important thing is don't touch the paint when its dry. Wet the paint and the towel, ALWAYS. That means pre-rinsing when washing and spraying the paint with a quick detail spray before using any type of wax paste or spray. Lubrication when cleaning/waxing will keep the paint looking brand new.
Also dry the car using the flood method and don't wipe the car dry. you want to press down not wipe left to right when drying.
