Sir JazakAllah
Mein khud bhi seikh raha hun abhi 
First thing with detailing is that ITS TIME CONSUMING
THEN u need to start from basic things like washing with double bucket method, get some products like a car shampoo like turtle ice, microfiber cloths & a good wax. Im not telling u to get all the stuff like clay, polish or compound because first i want u to buy & apply these simple products weekly or twice weekly & when u r up for it go for more products to explore
To abhi sirf apne hath se apni gari dho kar dekhen 
Wash with a shampoo, get some detailing cloth & a wax like Meguire's NXT or Gold Class
