Best lubrication for Mul-T-Lock?

[FlushingDIYer]

Hey all,

Just wondering what folks us to lubricate their Mul-T-Lock deadbolts. I've been using an Angal (off-brand Mul-T-Lock) deadbolt for three years and would like for it to last as long as possible. The keys are exact duplicates of the simple Mul-T-Lock keys.

Mul-T-Lock makes their own spray. But at $15 plus shipping, I was just wondering if there were a more affordable alternative.I've always used graphite sprays from HD or Lowe's or regular locks and deadbolts. Haven't had any problems since! I know the Mul-T-Locks are significantly more complicated, just wanted to know if anyone had used it in one of these locks before I jammed it up somehow.

Thanks much!

Just look up the manufacturers MSDS sheet for the product and I'll bet you'll find Multi's spray matches up to the same contents as any other dry silicone lock lube.

I would not recommend any wet lubricant in a lock. Wet lubricants attract and retain dirt that will wear out the lock.

In my Medeco locks, I use CRC Heavy Duty Silicone Lubricant:

Walmart has been the cheapest source I've been able to find for it.

CRC makes the best silicone spray that I've found. Silicone is dry enough that it doesn't collect dirt, and it is also water repellent (something you want in a lock).

As for graphite, it works in many locks, but I've been told that it can jam up Medeco locks, and I would have the same fear with Mul-T-Lock's small tolerances.

If my lock is sticking, I'll flush it out first with naphtha (liquid lighter fluid). This gets all the dirt out, but leaves no residue. Then finish off with a silicone spray and some vigorous key working (and cleaning).

I just checked it out... The only chemicals coming up are "liquefied petroleum gas" (36.2%) and "px17" (63.7%)...

Thanks for this information! If it works in Medeco locks, I'm sure it'd work in the generic Mul-T-Lock. Thank you for these pointers! I'll pick these up at Walmart later in the week.

Locks are one of those things that will last forever if, and only if, you take care of them...

I have had great success with "Super Lube multi purpose synthetic lube w/PTFE" on door locks both on cars and house.

I use Boron nitride powder (Ebay), dry powder, non- hydroscopic, slicker then Teflon, does not build up like Teflon powder. Dip key in powder, insert into keyway, work the mechanism, repeat once more, good for 1 year. Used Borden's/Remington Teflon spray for years, great stuff, but this is better, have a pound of this stuff.

I wonder if it'd work for ratchets, too!

It will work on anything, though it is a very dry powder. You can mix it with a little oil or grease if you figure it will work it's way out of a mechanism. Requires very little, as in locks, the amount of dust it forms dipping a key in it is very little.

The supplier you found is expensive, the one below is a lot cheaper, 8x the amount (100gram =almost 4 oz) for $15. Also the supplier you got mentions it is hydroscopic, my information is that it is hydrophobic, maybe depends on the particle size.

Tri Flow.

The best stuff on the market in my opinion. It is very runny though. Great penetrant as sell.

The graphite binds up most quality locks with tight tolerances I've found. Works ok in the looser, cheaper locks but still can bind some pins. We used to get a brand from the wholesale but I can't recall the name. It left a light film. Lok lube or something wierd like that.

The tri flow works awesome in my experience. We use a spray silicone but it doesn't pent rate down into the pins and chambers of lock cylinders, it just builds up. The tri flow has no issues getting into the tight places. I remove the lock and spray until.it comes out clean, the work the key a bunch to work it in. Wipe off any excess and blow air through the keyway to get any left over excess out. I wish try flow was alittle less runny but sometimes that's what it takes to free up something. I reach for that over pb blaster even. The locks for our yard gate at work get hit every spring with a few shots of it and they work great, the last lube would freeze up and gum up the locks.

The cosmetic grade is 2.5 - 5 micron, or perhaps even larger.
The lubrication grade is 0.5 micron. I just picked up a jar of the 0.5 micron stuff, and tried it out in two of my Medeco locks, and it works great! When I do my spring cleaning of the rest of the cylinders, I'll be putting it in a bunch more.

Before I used the powder I "washed" out the locks with a contact cleaner, inserted the key and worked the lock, repeated a couple times. All I used was the slightest amount of the dry powder possible, but it has lasted a couple years. I will need to do it again soon, this does not build up in the lock mechanism.

I used this supplier. Yes, price ***** but you will not ruin the locks. https://www.mul-t-lock-online.com/store/index.php?dispatch=products.view&product_id=91[/url]
