Rubber,vinyl parts maintenance in cars?

First I recommend you clean your engine bay with enginebrite foamy cleaner.....but you must wrap all of your sensors and harnesses with surran wrap.....not doing so will create shorts...

Be sure to do this when you engine is cool.

Then once air dryed....get some Meguiar's rubber/vinyl cleaner....and spray away LIGHTLY...using a cotton towel where ever you can....wipe it until you almost remove the cleaner complety off.....this will leave a clean, mor natural look to your rubber,plastic parts....

Once done, get office cleaner compressed air and blow the wire harness connectors/sensors dry....just incase.

Take your car for a spin just to finish drying it off and cooking the residual spray off....your engine should look new....

Be sure to take this time to inspect and or replace hoses and belts as needed.

Armour All makes different products. What you have is good for any rubber on the car.

A quick trip to the auto parts store and ask the gentleman in charge and he/she will set you straight on what to use. Also an detail shop would know and a phone call will take you about 2 min to get your answer.
