The SCREEN spline on my patio was very hard and I could not remove it no matter what I tried. I found this, sprayed it on the spline and waited a couple of minutes. Using the tool that has a bent sharp end, I was able to remove the spline! This worked great and now I will be able to replace the screens.

I have a leaky bathroom faucet. It's an old faucet. I figured I'd take a shot and change the washer. Unfortunately, I found that the under-sink shut off valves were totally frozen. I checked YouTube, and one guy said to spray some WD-40 on the valves and let it soak in overnight. I thought I had some in the garage, but I must've used it up. There was no WD-40 to be found. I bought this one and sprayed it on the valves. I wasn't really expecting much, because the cold valve in particular was totally stuck. I couldn't even budge it with a wrench. The next day I gave the valve a turn with the wrench, and it was totally free. I didn't even need the wrench. I could've easily turned the valve with my hand. This WD-40 came through with flying colors. Of course it worked, it's WD-40. If I could give it six stars I would. absolutely recommended.

People who use this product don't need to be convinced--it has a million uses. Keep it around your home just in case. I recently used it on old door locks and there is a big difference. I keep it in my car too.
