On this project, I clean a pretty dirty Skoda Octavia 1.6 from 2014. Because on Romania is winter time, but never really snow this year, the car is full of stones and sand and in almost 6 years it has not had a complete cleaning inside. Below you will find a list of all the products i use in car cleaning:
