Pro mechanic here, and WD 40 definitely has its uses: Lubricates moving parts such as hinges, wheels, rollers, chains, and gears Protects against rust and corrosion on tools Loosens rusted/stuck plumbing joints Loosens rusted bolts Lubricates and protects power tools Removes rust from saw blades Lubricates squeaky doors and drawers Prevents metal surfaces from rusting Cleans and softens paintbrushes Unsticks painted radiator valves Keeps lawnmower wheels turning smoothly Untangles jewelry chains Removes chewing gum from almost any surface, especially when it’s left on the bedpost overnight Wow....your copy and paste skills are commendable

I don't mind them. They kinda keep things rolling along. If they really wanted to be taken seriously, they'd sign up.

Pro mechanic here, and WD 40 definitely has its uses: Loosens rusted bolts A number of years ago I purchased 1 gallon of WD40, which cost me £20. Should see me through the rest of my life! My friend bought a circular knitting machine which was siezed. I left it soaking in a tub of WD40 for a few days and it now works fine.

I’m in the mechanical contracting business and have used WD 40 and other similar products for many decades. When used in the correct circumstances and applied properly, WD 40 is well worth its weight in gold & blue… 🤓

Ace Lube-E costs about 1/3 the price of WD 40 and will do anything WD 40 will do and better.

Got hold of a load more used weights recently. All had at least a little rust, some had so much that all the paint had gone and some had been repainted years ago in a yellow and had rusted again. I tried several methods to tidy them up.
The very rusty plates that had lost all their paint I cleaned, wire brushed and then brushed on virgin olive oil with a small paint bush. Olive oil has an acid in it that stablises rust and helps protect against new rust forming. Virgin has more of this acid than the other olive oils. It also gives the plates a semi gloss black/brown look that I really like. I let the olive oil do it's magic overnight and wiped them with a dry cloth the next day.
With the plates with just minor rust I gave them a clean, brushed on a little olive oil and then wiped off the excess immediately after with a dry cloth. I found the best way with this method was to oil and wipe clean each plate as I went rather than oil a load and then wipe them all after. Makes the paint nice and shiny again.
The repainted plates I put in two 15 ltr buckets, added about 150 grams of citric acid to each bucket, filled them with hot water and let them soak for about a week. This method took all of the paint off some plates but very little off others. It was great for removing rust though. With the plates where all the paint came off I left them to one side to get a little rusty again. It may sound a bit silly to let them rust again but I wanted to try a phosphoric acid rust converter (Check the label) on them that forms a protective black or brown layer but it does not work on rust free metal. The phosphoric acid has to react with rust. It looks good on rusty metal but sometimes goes a bit white on painted surfaces which is ok if you plan to repaint but not so good if you don't so it's best if all the paint is gone and a coat of rust has formed.
I had hoped all the paint was going to come off the repainted plates and I would have used olive oil or let them rust a bit and used rust converter on them but as there was so much yellow paint still on them I had to repaint them with a paint that requires no primer on bare metal and will etch itself onto existing paint. They came out looking good but if I had known that a lot of the yellow paint was not going to come off I would not have bothered with the citric acid and would have just repainted them especially as the paint I used can also be used directly on rust. I certainly won't bother stripping paint again and will just go straight for the repaint.
Bars and dumbbell handles. Citric acid works well at removing the rust on chrome but will very quickly start on the chrome so I wouldn't recommend walking away from chrome that is soaking in a citric acid solution. Check on it every ten minutes but don't let it take of all the rust as by that time it will start damaging chrome. I found it best to just use a brass wire brush (brass doesn't scratch chrome or steel) and a phosphoric acid rust converter. Some handles were very rusty so after the rust converter I masked up the ends and painted the knurled parts.
In conclusion all methods well for the different situations but I could have skipped the citric acid stage with the yellow plates, m8s.

Bruv, ever use CLR (calcium, lime, and rust remover) for rust? My homes sump pump quit several weeks ago due to calcification deposits that jammed the float switch mechanism that turns on the pump. I replaced it just as covid came around, so it should still be good. The whole thing was covered in white calcium due to the hard/mineral content of the underground water in my area. It's like a thin eggshell that when dry cracks off like a shell. I put the pump in a 5 gallon bucket with 1/2 water and 1/2 CLR and left submerged for 8 hours. Took it out and rinsed off and looks and work like new.

One thing I've had good luck with in getting rust off of metal is steel wool (SoS or Brillo pads).

I used CLR on a bullworker a few years ago. It worked quite well. Rust is not a problem. I use a steel wire brush for the plates and a brass wire brush for chrome and soak in citric acid if need be. It's just a few dollars for 150 g from the supermarket. It's used in cooking and for descaling kettles etc. I was hoping it was going to remove all the paint. I could have used paint stripper but that's more expensive, labour intensive, messy and the fumes are horrible. Citric acid is safe and fairly easy. It was just an experiment. I know now to not bother with stripping paint and just repaint with a self etching paint in future.

I tried ketchup on a very rusty curl bar the other day. It works surprisingly well at removing rust. It's the vinegar that does the rust removal. It's no good just brushing on vinegar because that will just dry before it's started working. I could have just gone over the rust with rust converter which turns the rust black but it also turns the rust stains on the chrome black too so I wanted to clean the bar up first without having to spend a lot of time doing it. I brushed on a thick layer of ketchup on one half and left it for about 24 hours before washing it off with a plastic scouring pad. Steel wool will scratch the chrome. I don't think it needed as much as 24 hours as I think the vinegar had started to attack the chrome. I'm not bothered really as it's not like it's ever going to look pretty. I meant to take a pic before doing the other half which was the reason I only did one half but I forgot and have now brushed on more ketchup. I have another really rusty bar so I'll try to remember to do it with that one. When I've cleaned off the rust I'll let a little surface rust build up for a day and then coat it with rust converter.
I also tried the ketchup on some rusty weights. It worked pretty good but leaving them in a bucket of citric acid and water for 24 hours and then a quick rinse off would have been easier.
