Houdini 2.5 Lock & General Purpose Cleaner Lubricant

The best lubricant we ever used around the house.

I worked in the hardware industry for a long time. So I am familiar with graphite powder and liquid graphite, wd-40, liquid wrench, 3in1 oil, and many more.None of these compare to this product. I’m in another industry now and I came across this on an Internet forum where persnickety gearhead debate tools, oil, coolant and other gearhead topics. Someone recommended this and I took a chance and bought a bottle.Worked great, lubricated the pins in the cylinder and smoothed the whole operation of the door lock, from turning the knob to putting the key into the cylinder.I had a sticky latch on my garage door and I tried everything including dry lube and graphite. Sprayed with this Houdini and the next day the latch springs back like it was brand new.What remains to be seen if how long this lasts. I did the garage and front door, plus one of the breezeway enters locks that felt “stiff” when inserting the key. They all work great now, but time will tell if this attracts dirt or doesn’t last.If anything like that happens, I’ll update the review.But so far this stuff works great.

Asked my locksmith what he used when keys get sticky because my front door is not too protected from the wind. He recommended Houdini. Also, I haven't needed to open my side door from the outside since my front gate is always locked. Never had to use the key. So since I bought Houdini I tried the key but it wouldn't go in. Used Houdini and now I can lock the door if I have to when working in the backyard.

What is it with so many people receiving this without the straw? It's pretty useless without the straw and since it's a non-standard diameter straw, it's really difficult to source a replacement. Sellers, quit removing the straws - there's tape residue on the can I received so I know it originally had one!

We used this on the weather-exposed locks on a bank of 80 mailboxes and it worked quite well. Keeping it handy for future needs.

This lock lubricant works very well. I'm only giving it 3 stars because it arrived with $3.88 postage due. The seller tried to send it as a letter. The post office flagged it because it was too thick to send as a letter. I didn't enjoy having to go to the post office to pick it up and to pay the additional cost.

Better for your locks doesn’t collect dust

Works great as a lubricant, but I am quite chemically sensitive and am able to quickly discern whether a product is low VOC or toxic to the respiratory system. This one, unfortunately, is worse than I thought. After breathing a bit of it in I experience tightness in my chest and know that I've inhaled something that is not good for me.Surprisingly I found the Seafoam deep creep brand to be much MUCH safer for use, no I'm not paid to say that or work for either company. I can barely smell the deep creep lubricant, don't notice any chest tightness when breathing it in, and if it gets on my hands I barely notice it, which I was surprised as it's technically a "petroleum" based product. I've tried most premium lubricants in search of the ideal one, which is what led me to Houdini. If you wear a mask and avoid breathing it in, it's great, but its just not that safe IMHO.
