JAR said:Kalkwasser with water. Heat about a cup in the microwave until it boils.(be careful, boiling water in the microwave can become superheated and explode into a violent boil when moved)
Use a syringe and inject "EVIL MONSTER" with the boiling hot stuff and watch it cook/melt before your eyes. (very satisfying)
This method works with just plain boiling water also.
You can inject into cracks and crevices.
I like to use a 20ml syringe with a 1mm stainless steel tip.
