WD40 Alternatives

[tonyabacus]

Searched the forums but found nothing, when we had the workshop we used a product that was extremely good and far more so than WD40, but unfortunately that was some time ago now and my memory can't recall the name of the product. This stuff used to penetrate and break down some of the rust to loosen parts rather than just lubricate it, so any suggestions please
Thanks

I used to use plusgas before WD40 came out

A mechanic friend put me on to an AC Delco product:

I've had good luck with Kroil

Duck oil in a liter pump-up sprayer is my go to penetrating oil (it's been around for donkey's years). I have a tin of Gt85 in my cars toolbox too which is good stuff.

The long-standing homemade trick of diluting pas fluid with acetone has served me well.

+1 on Kroil. Good stuff and I just found it also comes in a pint can in addition to the aerosole cans I've used for years. If I can't find Kroil, several of the auto parts stores sell PB Blaster, which is better than WD 40, which is not really a derusting agent.

Even though it's not sold as a penetrating fluid I've discovered that GT85 is very good, much more so that WD40 in terms of freeing off rusty bits.

Aldi often have it on special for £2 a tin.

My preference is to buy old cars from dry/arid climates , when I can't I have been using PB Blaster to help with rusty fasteners , I save the WD40 for other uses.

PS- not sure if PB Blaster is distributed outside North America.

I have read that the old timers (like my parents age we're talking really old) used kerosene (paraffin to the Brits). Thinking about it, it would seem about like acetone and oil; a mix of small and large molecules.
As an aside, I had an English bicycle (Rudge Supersport) with a hub gearchange. The service for the hub called for topping up with paraffin. I overheard, at the Bike Shop, of a customer that had melted some wax and poured it into his hub-changer! They seemed amazed that the guy had read the instructions and followed them!

Hey, what's this old timer bit, we may look a bit wrinkled but that's only on the outside, inside we are full of beans and these wrinkled containers have a lot of useful info stored up inside them, as shown by some comments above.

So beware old timers can bite back, old timers indeed, whatever is this forum coming to.!!

Plusgas is different and is to release rusted things. WD40 is only a Water Dispersant.
Plusgas is the one to used on rusted nuts and screws. WD40 is just to smell nice
