Im using Liqui moly wash and wax, its price was 800Rs if im not mistaken, 500ml.
It does awesome job, its mild on paint, and great for dust n greasy places... and have 5MFs, 1 water magnet and 3 applicators.. all what i need!
In past i also had a engine degreaser spray... it was a sweeeeet item too! But i emptied it quickly!
Armor all is 550Rs, turtle detailers start 900-1200-1500Rs.
Best value for money is armor all spray!
