Guys my servant sahab washed my car with tht "Gaaey soap" which is not coming off. From the body, it has, after 2-3 washes of shampoo but not from the glass.Since it was parked under sunlight, the soap dried and seems like it is impossible to clean it.
I washed the glass with surf, shampoo 2-3 times but no good.Even by scratching hard with my finger nail it doesnt come off
Wht to do!!!?
Thinner?
Boiled water?
