Product Description

Product Description

Master Lock 2300D pen oiler lock lubricant with PTFE. Over time, airborne dust, dirt, and chemicals can settle on and in locks and create friction inside the precision locking and keying components, thus interfering with the function. Locks must be maintained to keep them functioning properly and lengthen the product life. This is the ideal lubricant formulated specifically for locks. What is PTFE? PTFE is the acronym for Polytetrafluoroethylene, which is the most slippery material known to science today. All surfaces have microscopic irregularities, which create friction when rubbed against each other. The introduction of PTFE into these irregularities smoothes out the surfaces, reducing the wear and sticking that friction causes. The most familiar name of PTFE is Teflon, which is the registered trademark for DuPont’s non-stick cookware. Where can the new lock lubricant be used? Everywhere. This formulation is ideal for padlocks, door locks, automotive, marine, and multipurpose applications. The 2300D pen oiler is convenient for consumers and can easily be applied to keyways or shackle holes.

Specially Made for Locks, Here to Buy Tube #2 After Four Years
Well.I bought my little tube in 2015 (yes, almost 4 years ago), and I've been using this occasionally over the years, more as a preventative measure than anything else.Yesterday's events have encouraged me, however, to write a positive review for it.A Master lock on my property has been locked outside in the South Florida elements for at least several years, and during that time, not only did it go through Hurricane Irma, but it never got used (i.e. unlocked).Yesterday I needed to finally unlock it, and just as I feared, it was rusted shut. Although the key went in, it wouldn't turn a bit. I didn't want to wait, and I really didn't want to shell out $$$ and buy a bolt cutter, so I did some research, and went back there again with this little tube and a hammer. Greased up the holes, waited, banged the lock, jiggled key in lock. Repeated several times, and voila! it worked. The lock still isn't working buttery smooth, but who cares, I got it off.Don't know what's in this lubricant exactly, but it sure loosened up the rusty insides of my Master Lock, giving me access and saving me $.The lubricant i have is actually so old now that it's not even that runny, and the label is cracking too, but it still worked like a charm, and really proved itself too. :-DSo,I'm here to buy another tube after yesterday's events, and although $5 for this little thing sounds expensive, for me that has worked out to be $1.25 a year on 3-4 padlocks, for saving me a lot of backyard sweating and cussing (which I do enough anyway), and emergency trips to the local home improvement store, so it's worth it!Also, I don't know if regular corn oil would have worked just as well, but this lubricant specially made for locks claims it has "PTFE" so I dont want to use regular cooking oil or WD-40 and ruin perfectly good locks or make a bad situation worse.That's a picture of my old lubricant, the lock which came off with its help, and the q-tips I'm using to clean out its insides, showing all the rust.Recommend.

Reviewed in the United States on August 25, 2019
Well.

I bought my little tube in 2015 (yes, almost 4 years ago), and I've been using this occasionally over the years, more as a preventative measure than anything else.

Yesterday's events have encouraged me, however, to write a positive review for it.

A Master lock on my property has been locked outside in the South Florida elements for at least several years, and during that time, not only did it go through Hurricane Irma, but it never got used (i.e. unlocked).

Yesterday I needed to finally unlock it, and just as I feared, it was rusted shut. Although the key went in, it wouldn't turn a bit. I didn't want to wait, and I really didn't want to shell out $$$ and buy a bolt cutter, so I did some research, and went back there again with this little tube and a hammer. Greased up the holes, waited, banged the lock, jiggled key in lock. Repeated several times, and voila! it worked. The lock still isn't working buttery smooth, but who cares, I got it off.

Don't know what's in this lubricant exactly, but it sure loosened up the rusty insides of my Master Lock, giving me access and saving me $.

The lubricant i have is actually so old now that it's not even that runny, and the label is cracking too, but it still worked like a charm, and really proved itself too. :-D

So,I'm here to buy another tube after yesterday's events, and although $5 for this little thing sounds expensive, for me that has worked out to be $1.25 a year on 3-4 padlocks, for saving me a lot of backyard sweating and cussing (which I do enough anyway), and emergency trips to the local home improvement store, so it's worth it!

Also, I don't know if regular corn oil would have worked just as well, but this lubricant specially made for locks claims it has "PTFE" so I dont want to use regular cooking oil or WD-40 and ruin perfectly good locks or make a bad situation worse.

That's a picture of my old lubricant, the lock which came off with its help, and the q-tips I'm using to clean out its insides, showing all the rust.
