frame rust removal

[Grewth]

I need a localised chemical rust killer to treat the frame of my Heritage Special.
I'm planning some frame mods later on, so I just want to kill the rust and hand (brush) paint everything for the time being.
I've got an aversion to overpriced overhyped snake oil.
Is there anything commercial out there that will work.
In the past I've used "Brick Acid" to strip rust.
Now I could do with finding a gel version

This I what I need to deal with

Wire brush then

Not sure what it is called in English but has been used for at least 50 years Rust protective paint
In steel building and shipping machinery ask at the paint shop they must know it.
Usually red and in the 70 ies contained Thinner so it was intoxicating if in closed spaces Is it thinner in English also
Then on that the colored paint top surface in this case black that can be found in high gloss if one wants that.

Looks OK and wont rust ., After a couple of years the surface can loose its sparkle .then you just brush paint over it .

You can even skip the rust protective paint .. As long as the surface is wire brushed . And wiped with a solvent
The paint is normally sticking good enough
As in this case when it will come oft within a few ears

The red stuff Rust protective paint is the real deal I painted inside a rear fender with no over paint
No rust I got comments so I eventually painted over it with silver paint. Just because it looked nicer.
But no rust.

This is what I use. I’ve been using it for many years.

I’ve used a product called Krud Kutter with great success. It’s a rust converter in gel form. Between that and some coarse bristle brushes it turned out well. Check this link for my rustoration attempt. Starts at post 47.

Thanks Guys.
I just bought this (because it was half the price of the stuff in fancy packages)
It doesn't actually name the active ingrediant but I'm assuming Muriatic Acid.

Naval Jelly is a localized rust converter. You can get it at most auto parts stores.

I believe that's phosphoric acid.

There you go. That should do the trick. I use a black enamel spray paint to re-cover it. You could even brush it on if you wanted for more control. Something I did that helped blend with the original paint was after the paint had flashed and was almost dry, I used a plastic grocery bag and rubbed over the surface. This cut back on the gloss finish and blended in with the slightly faded factory paint.

I've had super results with this. I got a center stand that was pure rust, brushed all the loose rust off and sprayed it and the rust hasn't come back in 10 years. It won't stick very well to anything but rust, but loves rust. Result looks like flat black paint.

Phosphoric and sulfuric.

Thanks for that.
Not too common in the UK, but available.

Thanks also.
Available in the UK and relatively inexpensive too.
I'll be ordering some soon.

In the pics the rust didn’t look very heavy. Wire or nylon brush to get the loose stuff off then paint with Rustoleum or Tremclad rust paint but 100 % sure if those grand names are available in the UK . Another great option is to clean the loose rust off and degrease. Then paint with POR15 paint. Goes on nicely with a brush and lines flow out well. Need to topcoat the paint with another coat to protect the POR15 from UV degradation.

I've never heard of Tremclad before, apparently not generally available over here, except maybe from a specialist importer.
Rustolium are well established over here one stockist listing 129 products.
