homayoon bhai dont have aspire new interor pic 
about engine bay cleaning
pls ref below pic, i used this pressure spray bottle, easily avilable at hyperstar lahore even metro price roughly rs300 to 350
i use trutle presoak its liquied form engine de-greaser, use 1 pat this de-greaser and 5 pat water in said presure spray bottle, cover all electric things in engine by any plastic bags than spray this solution on one part, wait couple of minuts than use some brushes to rubbing and than simple water to wash, however for new cars dont need much rubbing, simply spray solution wait few minuts than wash with water, for safty reasons i also use same presure spray bottle for water wash. for metal parts u can apply any car wax, synthetic wax would be better and for plastic parts apply any tyer dresser or interior protectant 
its real good de-greaser and here you go for its results
