Thank you very much Sir ! I am very very happy
after reading your inspiring comment. To my surprise, my car is as quiet as it comes straight from factory, no squeaking noises anymore nor that bloody chir chir :). Alhamdo Lillah, engine bay of my car is quite clean but still it needs some professional detailing with those degreasers. Exterior of my car is also fine but not excellent because had never got time to detailed it properly as it is a daily runner. Moreover, I am also very much interested in detailing my car with those meguairs products but actually my problem is that I don't know which detailing product my car's exterior needs for good results. Bcz there are too many detailing products in the market. And also I don't know the exact procedure & steps of a detailing session. So , I am very much Thankful to you, if you suggest me some specific detailing products with their step-by-step application procedure 
And those "chaddi & phatti hui bunyaan" are extremely reliable during such types of jobs
