This is exactly what I was going to say too, that now the market is over flooded with such cleaning gadgets.
If you’ve tried the imported and expensive one like maguiers, mothers, Coach Chemi, Turtle wax, etc. then I will suggest you should give it a try to local products. There is a person I know from Lalamusa. He produces the cleaning chemicals and supplying to whole PK. Its his online biz.
He will share you many of the videos. I’ve tried his products and still have some in my shelf. They works fine.
I am suggesting this since commercial steam washing of cars is almost replaced with such gadgets.
Even you call people at home and they will do cleaning of vehicle like its new. Services at door steps are available now.
