Something you might like to try.

I've found a product that you'll probably want to know about... It's called JL69.

Basically it's made by a company called Juice Lubes that started making things like fork oil, chain lube, grease and brake cleaner for bikes. But they now do a grown up's version of WD40/GT85 called JL69.

You can get it from bike shops and it's a little more expensive but seriously it works!

The description of it sounds just like WD40, GT85 - and even the product name is similar (two letters followed by two numbers).

I would like to see a comparative (scientific) test of all of these products. Something like a piece of freshly shot-blasted mild steel with a squirt of each of them in different locations then left out in the rain to see which shows signs of rust first and last.

I've tried various different types of spray lube - and to be honest they are all pretty similar in terms of protection & performance even though all of the manufacturers make bold claims about how good they are compared to the others.

You can make your own - by mixing your favorite heavy oil or grease with thinners. The result is thin enough to run into the smallest gaps and penetrate. The thinners evaporate, leaving the oil / grease behind. I've found this works every bit as well as any of the off the shelf brands!

By coincidence, the spray I have mixed up (GP Grease and rapid paint thinners), I've marked up as SJ67 - my first two initials and birth year. I suspect that might be where all the other names come from too?

I use GT85 on my bike sprockets & chain when offroading. brilliant stuff.
I also use it on the electrical contacts under the bonnet.

You should try the new product.. I've had it in at work for ages and it works an absolute treat!

"It’s excellent searching power also results in the release of all rust bound parts without the need the for a six foot bar on the end of your spanner and a blow torch…"

Right, I'll get a can, and I'll be testing that one out.


(What will I do with the cracker bar and the 6' scaffold pole now?)

sell it to a landrover owner?

My preferred penetrating spray is plusgas, Halfwits stock it sometimes.

WD40 IIRC got it's name from being the 40th attempt at making a Water Displacement spray.

Plusgas for me too.
WD40 is a water displacer, not a release oil.

Actually, diesel does a better job as a penetrating oil, but it smells.


The JL69 arrived, but I've not tested its release abilitis yet.

inox for me, the usual fishoil based anti-rust, anti-corrosion lubricant and general loosener.
