What is the best method of cleaning the EGR valve? i.e, the best way to get the crud off it?
I have heard people say there are 2 stages (after removal):
1. Give it a good scrub with Carb Cleaner and a toothbrush to get the main dirt off, then
2. Soak it in petrol to get the hard to reach and more stubborn soot off.
I want to clean mine soonish, with the minimum spent and minimum fuss.
Is the above method the best for this?
Being a novice I am naturally wary of handling petrol as it's flammable.
After the EGR has been soaked in the petrol do you have to make sure it is bone dry before refitting it to the engine?
Any other hazards to be aware of?
