EGR cleaning sprays. Do they wreck the engine?

The EGR Cleaners that you spray into the air-intake. Whats the story with them? If they are supposed to dislodge soot and carbon, then I guess it goes straight into the engine??

On the other hand are they any use, as opposed to taking apart the EGR, throttle body, etc? To get the heavy dirt out I assume I need to take everything apart but can the spray be used every couple of months to keep things clear or are they a no go?

thanks.

Best to take the EGR off and soak it overnight in carb cleaner than trying to clean it on the car. Just be careful if it has any electrical connections on it to not submerge them.

Other than that if you want to do it on the car use a brush with the cleaner and try brush the carbon out of the valve and not into the intake, can't imagine it would do any harm to the engine as the intake beyond the EGR valve is bound to be covered in carbon also.

Another reason to take the EGR off, you'd be able to give the intake hose a good clean, can get awfully blocked with carbon buildup.

Agree with above, not that hard to take off and clean manually. I would only see the spray working if it was very low miles & done regularly as it can be very baked on

Thanks, out with the scrubbing brush it is then!!
