All engines, whether they have EFI systems or standard engine components, require an occasional clean, especially if you are into performance driving or long road trips. The two most common cleaning operations include fuel injection systems and throttle bodies. The fuel injection systems are cleaned by professional services, and best left at that. Throttle body cleaning is a much simpler operation and can be performed by anyone with a basic understanding of car engine mechanics.
Cleaning a throttle body will improve the car’s performance, will improve MPG, and will improve power and torque performance. The best way to notice a declining throttle body is by feeling for a rough idle, stumbling initial acceleration or even stalling.
Take peek inside your throttle body, notice how full of gunk, resins, carbon deposits and unknown substances that just like to cover hidden surfaces.
In this article, I present you with two throttle cleaning fluid options and three throttle cleaning brush sets. Cleaning fluids are essentially different formulations of Methanol, Topline and Acetone with a CO2 pressurized gas as venting agent. Throttle body cleaners come with no Naphtha content, as such, they do not leave a residue.
Brushes are even more basic and they come in steel variations using nylon. The top rated brush sets will come with at least 15 pieces of varying diameters including brushes and needles.

How to Clean a Throttle Body
Cleaning a throttle body is not a big issue, while there are some throttle bodies that are hard to reach or open, you might forgo cleaning it yourself and take it into the shop for cleaning. If your throttle body is easy to locate and is easy to disassemble, then just remember that it’s made of aluminum, and the brushes are steel.
When brushing, try not to let the brush shaft rub against the air intakes, since this will chaff them. Only allow the nylon contact. When using the needles, make sure you only insert them to remove the dirt, don’t scrape the sides.
- Torx screwdrivers or socket wrenches
- Brush and needle set
- Eye protection.
- Throttle body cleaner, or acetone
- Household oil
- Cotton swabs
- Paper towels
- Rubber gloves (or surgeons gloves for better feel)
- Park and secure your vehicle in a well-ventilated location
- Pop the hood and disconnect the battery negative
- Locate the throttle body which usually between the air cleaner and the intake manifold
- The throttle body is made from aluminum
- If you have an issue finding the throttle body, have someone sit in the cab and press the fuel peddle, then look for movement, that will be the throttle shaft that leads to the throttle body.
- The throttle body is attached to air-intake tubes, check which tools you need to disconnect these, label each connection before removing it, use a colored tape on the throttle body and the hose, so you match each one when returning it.
- Do not disturb or disconnect the electrical wires.
- Make sure you are not damaging any gaskets, or you will need to replace them.
- Put on your eye protection if you haven’t done so yet, and also your rubber/surgeon gloves.
- Spray into the air duct and use the brushes to clean the sides.
- DO NOT LET ANYTHING FALL INTO THE AIR DUCT OR THROTTLE BODY
- Brush all the surfaces until they are clean, you will see the aluminum shine.
- Using the cotton wool and the oil, swab the throttle shaft slightly (don’t overdo it) and one drop of oil to the rotor too.
- Using the paper towels, clean up all residues and liquids from the engine surface that fell during the cleaning operation.
- Re-assemble the throttle body ducts
- Tighten the hose clamps.
- Clean the surfaces of any tools and waster.
- Reattach the neghative tyo the battery.
- Close the hood.
- Start the engine.
Sometimes engines will start a bit rough, but that’s common. After the initial ignition, the engine will start to perform better than before.
Leave the engine running for a few minutes, and then take it for a test drive. You will notice that your engine now performs significantly better and your throttle reaction together with your overall control has improved.
