Review on Biodegradable Lubricant for Master Lock 2300D by William Stewart

I bought this bike mount lock oil from Revain on the recommendation of many users. A few weeks later, after being pounded by hurricane after hurricane, I wanted to open my barn and couldn't even get the key to put it in the lock - no exaggeration. The last storm was such a strong wind that we must have gotten too much rain in the lock. After trying to insert this key for a few minutes, I remembered that I had just bought this oil. Luckily, having just bought it, I knew exactly where it was (you all know what I mean). I injected something into the lock and inserted the key. Within 15 seconds, not only did the key slide in smoother than ever, but the lock worked like new. I didn't buy the product for this purpose, but it certainly fits - now I just have to remember to do it once a year. Very good product - glad I had it on hand.
