How to clean Toyota Corolla 13 by carbon deposition?

Disassembly and washing: The most traditional disassembly and washing method is to remove the engine from the car, and then wash it slowly with detergent to clean up the carbon deposits. The advantage of this method is that it can be cleaned and the cleaning effect is the best. The disadvantage is that it takes a long time, and because of the high technical cost, it is expensive.

Hanging a bottle: Hanging a bottle means hanging a bottle-shaped tool above the engine, pouring the cleaning agent into the engine through a conduit for cleaning, and then discharging the dirt mixture through the engine. The method is simple to operate, and the cleaning effect and cost are moderate.

Matters needing attention in cleaning car carbon deposit

Under normal circumstances, we only need to clean up the engine carbon deposit when the engine has adverse reactions caused by carbon deposit, such as idling jitter.

It should be noted that, under normal circumstances, the carbon deposit in the engine has basically accumulated to a certain extent when the vehicle travels for 20,000-40,000 kilometers, so if you don't know much about the adverse reactions caused by carbon deposit, the cleaning frequency every 20,000-40,000 kilometers is correct.
