    5 Stars
    Worked when nothing else would.
    Used this to get a VERY stuck, VERY old sewer pipe cap out. Before using this, three very strong men and woman, a large variety of wrenches, and a few tears of frustration couldn’t get the dang thing to budge. I had never truly had a nemesis before this stupid pipe cap...it even destroyed the basin wrench with a little help from a cheat bar.But then my local plumbing supply company recommended penetrating oil (and hitting it really hard with a hammer). One Amazon order, a few prayers, and one personal vendetta later...Voila!That whole sink is still my nemesis, but at least I can carry on the war to other battle grounds.TLDR: I highly recommend liquid wrench. It worked when nothing else would.

    Hard to find in big box stores lately, but found here on Amazon. Liquid wrench is the only brand I'd use to provide that added penetrating for rust and sticking of parts or screws. Worth the price and it's the best brand to use overall. A little goes a long way, so be careful how much you use. Highly recommended for the weekend mechanic or weekend DIYer around the house.
