Is it useful to hang bottles to remove carbon deposits?

For some novice drivers, whenever they encounter car problems, they will definitely be at a loss. Here is to introduce whether it is useful to remove carbon deposits with a bottle of water. I hope I can help some novice friends to avoid detours and enjoy the fun of car life better, which is helpful for car use and travel. Okay, let's get down to business. Carbon deposition can be removed to some extent, but the effect is not particularly obvious. The key to cleaning carbon deposits by hanging bottles is to spray cleaning agents on the throttle and intake manifold of vehicles to achieve the effect of cleaning carbon deposits. There are two ways to hang the bottle, one is before the throttle and the other is after the throttle. Front: After the engine is ignited, you need to find the position of the throttle. Put the cleaned fuel nozzle in front of the throttle, and the suction of the engine will automatically suck the cleaning liquid in. In this way, the effect of cleaning the throttle is achieved. Behind the throttle: Pull off the PCV breather pipe behind the throttle and place the fuel injector in this position. When the engine is working, it will also suck the cleaning agent in, so it can clean up the carbon deposit. In the actual cleaning process, you will find that the cleaning effect is not very good. Only the carbon deposits in the intake pipe have been removed, and there are carbon deposits on the back of the throttle, the top of the piston and the top of the cylinder head. Of course, the effect of cleaning carbon deposits with bottles is not very good. In the process of using vehicles at ordinary times, it is necessary to regularly maintain the use of vehicles, regularly maintain vehicles, and clean up carbon deposits in time.
