## Questions & Answers

**Q: If using this for a car key to get the ignition to work better without sticking; should you apply this directly on the car key or inside the ignition?**
A: The formula within this lubricant was designed to be best used with padlocks, cylinders and mechanisms within the lock.

**Q: Is this product good for use with a combination padlock (lock without a key.)**
A: Pamela I don't really know. I've only used it on my key locks and works fine with them. If you put a few drops in the shackle opening it should work ok.

**Q: Would this be suitable for micrometers and other delicate measuring instruments?**
A: Yes it should work fine on your micrometers and calipers, especially if they are kept climate controlled.

**Q: Silicone based? I didn’t see where it says, only biodegradable?**
A: PTFE formula, whatever that translates to. Good stuff.

### ⭐⭐⭐⭐⭐ Review
*by B***T on 25 August 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. Recommend.
