I work on the length of SCC. Sometimes (very rarely) in the houses of the old fund, the cable channels are blocked to such an extent that only the conductor passes. The cable is no longer there. It is customary to lubricate the cable with car oil. It works on ur. Five more pass after him. A couple of times it was not at hand. I took ordinary vegetables from subscribers. The effect is no worse. But he did not find him the other day either. Then I lubricated the cable with mayonnaise.
So now I wonder... What other culinary tricks to use in the installation business?
