Note: Use protective gloves and eyewear while cleaning your throttle body for safety. Throttle body cleansing solutions may cause skin irritation and emit dangerous fumes. Because the cleansers are very combustible, stay away from cigarettes and flammable objects while working on this task. Leave your car in an open, flat spot with good lighting. Because of the toxic smoke produced by the cleaner, do not undertake this task in an enclosed space like the garage. Before beginning the cleanup procedure, unplug the ground connection from the batteries for safe operation. Name-tag any gaskets and bolts connected to your throttle mechanism or air vents before removal so you can remember where to put them back after the cleanup is complete. Remove any electrical cables. You may need to use a Torx or Phillips wrench to loosen the clamp nuts that fasten the air vents. If you can’t loosen the air vents, bring your car to a qualified technician. After removing the air ducts, you can now access your throttle body where the cleaner comes in handy.  After you've put on your protective gear, spray the cleaning solution onto the air ducts.  Clean dust and unwanted sediments using a tiny brush, and then wipe them away using paper towels. It's going to take many sweeps to get a spotless surface. You can use a flashlight to look for any dirt that you may have missed. Apply a bit of multi-purpose oil to the throttle shafts with a cotton bud. This facilitates the easy movement of your throttle blades. Clean your motor and surrounding area with wet wipes to remove residual fluids or filth. Assemble the air vents and ensure your clamps are tightly fitted. Take whatever you're using out of the car's hood before restoring the batteries.  Then, get the motor started; car readjustment might take a few minutes. Warm up your engine by letting it idle for a couple of minutes. Finally, take the car out for a trial run. How effective this cleanup is on performance depends on the amount of gunk cleaned out of your throttle body.
