Houdini 2.5 Lock & General Purpose Cleaner Lubricant

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.

Amazing stuff. I put a quick shot in all my keyhole & latch mechanisms. Sticky tumblers are now smooth. The seller also gets 5 stars. This was packaged nicely & shipped quickly.

A very good product actually. And smells quite good ( like oranges)

It works good, it smells good, it's pricey but tolerable, and does loosen all the nasty from mechanical instruments.However, it claims to have no oil, yet it leaves a oily residue everywhere you spray it, I though it would evaporate, but here we are.Not bad overall.
