About WD40 you have nothing to say really. I am always impressed with what the agent can do. So I managed to peel residue stubborn labels that were previously to persuade either with concentrated alcohol or with detergent to cooperate. The variable spray head which has both a nozzle and a fold-down zerstäuberähnliche tube for inaccessible places, which means take as to where it is needed. The fact that the tube is now firmly attached, do not have to constantly look frustrated, too.
