Wd-40

What would we do without this amazing product?

When I turned the heating on, I noticed that I had one radiator that wasn’t warming up and a quick examination showed that it was due to a stuck TRV pin. During the warmer weather over the last couple of days, I sprayed WD 40 on the pin and left it. Then this morning due to it being a cold misty morning here, the heating came on and the TRV worked again.

Of course, I had to get some more because I couldn’t find my can of it. Which will no doubt turn up when I am looking for something else.

For those interested, a link to the history of WD-40

One more time for the gipper…. For things that move but shouldn’t, Gaffer Tape and for things that don’t move but should, WD-40 :joy::joy::joy::joy:.

Exactly the same. Two TRVs were stuck: 1 I freed by turning it repeatedly from 5 to off, the other I attempted to free gently using pliers.

As it was still not working, I applied a tiny amount of WD40 using their straw-like applicator and the TRV is now working correctly.

Use with caution though, it’ll destroy rubber

That’s true of natural rubber.

It’s fine with most rubbers such as nitrile, hypalon and viton.

It’s a good idea to switch the heating on every so often in the summer and exercise the valves.

Be careful with WD40, it can damage some plastics and it might be the TVR pin seal has a plastic content.

I too have experienced sticking TVR’s, for the last 5 yesrs or so I’ve put a few drops of 3-in-1 light oil on the pin about once a year. This year I didn’t do that but all TVR’s worked OK on their 1st season heat up.

Once used WD40 to light a barbecue on a stubbornly windy day.

The Wiser system we use cycles the valves periodically when not in use.

A couple of squirts on your knees each morning works wonders!

GT-85 (made by the same company) is better.

I use more WD40 than GT85. Tomorrow I’ll be using WD with wet’n’dry to polish some camshaft journals.

I find GT-85 better for cleaning as it’s thinner and more penetrative than WD-40.

GT-85 is the best for folding car door mirrors, locks etc WD can get a bit messy.

I’ll be micro-polishing the camshaft bearing surfaces rather than cleaning, WD is just the ticket for this.

Some years ago my then 95 year old neighbour arrived at my back door and demanded to know if I had any UB40.

Took a few moments to realse it was lubrication she was after not an unemployment benefit form. :roll_eyes:

And the new cans seem to now have a fixed/hinged spray spout (rather than the finicky losable straw) - a definite upgrade !

I saw on a bike forum recently someone saying that WD-40 is a degreaser primarily, ie It’s not an oil or lubricant.

That post on that other forum made me wonder what WD-40 is chemically And whether that post was correct?
