Quote: "Damp sponge" you say ...
 
 Well, sorry, but for me everything goes beautifully, the tip is just as shiny as new. and the sponge to the tap for a moment and squeeze. 
 Quote: - and the temperature of the tip is what ??. 
 the fact that, as I said, the tin has only a topic, the very beginning of the melting of the tin, about 200 degrees, then everything goes down, the sponge does not burn because you only need to use the spike tip because you do not hold the grout on the sponge for five minutes only 0 , 5 sec - for (t) reluctant I will say that it is like you want to clean something, wipe it.
