 |
|
I took the daily "modern" to an old established country garage on Friday and happened to arrive at "morning cuppa" time and I was kindly given a mug of tea with enough tannin to scour a sewer pipe.
The shelves has penetrating oils for their own use - the usual, WD40, Duff and others and I asked one of the joint proprietors which in his opinion was the best.
"None of them" was the short answer.
Their favourite and most used was a 50/50 mixture of "Three In One" oil and white vinegar.
Apparently it will release or unseize anything that they would not heat up with a gas axe and is ideal for rust seized nuts and bolts.
I'd never heard of that one.
Have you?

Acetone + diesel or ATF seem to be the favourites 'round 'ere.

| I've tried the acetone and ATF mix and not been very impressed TBH - maybe the grade of ATF makes a difference? Plusgas is my preferred fluid at the moment, but hard to come by these days - you might find one or possibly two sellers on fleabay but forget finding it in a shop anywhere nearby. I think it's more common in aerosols but I don't like aerosols for stuff like this, you seem to pay a lot for the can and propellant while getting very little of the product, much of which will go to waste anyway. |

Although it sound unlikely I have had success with Coca Cola.

I had a "tin" of Plusgas that lasted me over 10 years, the same sized aerosol lasted about a month  as well as all propellants, loads gets wasted as it sprays a large area rather than just adding the couple of drops that a tin would.
A tip I was once given when dealing with a seized component is to actually try and tighten it a tad first....

Back in the day (1960's Coal Board), we frequently had to deal with seized bolts and the practice of applying tightening force first was often the norm. Plus-Gas in gallon containers was the product of choice.
When I worked at the Vinegar Brewery, a mixture of diesel and white vinegar was both popular and abundent, I have no idea of the proportions but the idea was the vinegar softened or dissolved rust and the diesel provide lubrication to the newly acquired spaces.
We didn't have the same access to impact wrenches back then, I wasn't convinced until I was invited to try one. Two days later I went shopping.
Used in conjunction of heat (where appropriate), release/lubrication agents and gentle repetitive persuasion I would not want to be without one. Used it only a handful of times in the last 2 years but saved hours or even days of difficult and tiring struggles. |

I like plus gas, have a couple of tins that I decanter into a small pump type oil can, I also have an aerosol version should it be more convenient.
For those times when a small component needs de-seizing, I place. It in a container of diesel, leave for a few days and it seems to work.

The solution I arrived at was ...soak it in GT85...leave for ten minutes, then thin motor oil...the former seems to get the latter moving into the invisible gaps!
