How to treat rust?

Hello everyone!
I recently purchased a product intended to solve a specific rust-related issue, but unfortunately, I am disappointed with its inefficiency. Today, I am reaching out to you in the hope of receiving advice and recommendations for finding an alternative solution.
The product in question, which is Rust Converter, promised remarkable results, but despite following the instructions, I did not achieve the desired effects. I have invested time and money into this purchase, and I am truly dismayed.
I am seeking your experience and knowledge. If you have encountered a similar situation or if you know of more effective alternatives, I would be extremely grateful if you could share your recommendations. Your valuable assistance will help me address this issue and make a more informed choice in the future.
Thank you in advance for your support!

On our sailboat, and in a welding shop I ran in the 80’s we used Ospho, brush it on let is sit for a bit then wash it off with water. It is advertised on Amzon.
Basically it is phosphoric acid, it turns ferrous oxide into ferrous sulphate which is water soluble.

What’s that got to do with CNC?
Sounds like you’re trolling.

@JanVanderlinden @Fernand434,The OP was asking about ways to deal with rust. In the '70’s & 80’s was involved in Yachts and steelwork and discovered Ospho.
I assure you I am not trolling, nor do I have any interest in Ospho, but did find it to be the best simplest method for rust removal.
It works chemically the way Naval Jelly works but is cheaper and easier to use.
Thank you.
