What would be the best way to remove the rust off our patio table?
Clr Calcium lime and rust remover . Is that stone like table top ? Than maybe cut muriatic acid .
My best process is to just buy a gallon of white vinegar from the grocery store (really cheap).
Then a 6-pack of "0000" steel wool.
Using a sponge and gloves —- liberally apply the vinegar, and let it set for a few hours. Then use the steel wool to rub off the rust.
Rinse and allow to dry thoroughly.
Nest step might be to paint the metal with the Rustoleum of your choice.
Vinegar is a mild acid —- and is good for a lot of things.
I use it when restoring old furniture to soften decades old glue joints, or to clean up a joint when the excess glue squeezes out of a biscuit, dowel, or mortise & tenon joint.
That looks like just surface rust that should come off nicely.
Best, Fred
Thanks for the advice. I'll try the suggestions tomorrow
Is that a stone insert? How about turn it upside down?
It's a metal table
CLR
I will defer to Benni on this one that has way more experience, but I have had good luck with Evaporust products. Cant remember the last one I used but the whole concept/process was basically turning the oxide/rust into another kind of oxide that your were able to paint over and would be inert.
put a thin coat of Vaseline on the metal frame surrounding the white inserts(..stone?)
if its polished limestone or marble, acids will etch it quickly. if its a honed finish, it won't make much difference in appearance and you can wet sand it with 400-800 wet/dry sand paper after the acid wash.
wear gloves & goggles.
spot cleaning leaves clean spots .acid wash all four inserts and rinse with baking soda and water to neutralize any acid residue creeping around the metal edges that can cause rust/corrosion issues later on.
if the acid cleaner needs to soak in for awhile, lay an old bath towel or paper towels over the rust area to keep the solution wet were you want it.
don't use acid solutions over finished concrete as it will instantly burn spots into the finish. flood concrete surfaces with water first or do it over wet grass .
It's not concrete or stone, it's metal
Here's the result after some CLR....I'm thinking I'll try vinegar and steel wool next...
I was going to suggest Naval Jelly or Evapo-rust which I have used in the past. When looking for a comparison review, I found this DIY (https://www.youtube.com/watch?v=fVYZmeReKKY&ab_channel=BeyondBallistics)video.
Hmm, looks interesting.
Lime Away (may discolor the metal), Naval Jelly, muriatic acid, wire brush and sand, bead blast it, sand blast it, soda blast it.
After any of the above paint with Rustoleum rusty metal primer then topcoat then clearcoat with urethane.
Wash it, clearcoat it with urethane, call it an antique.
Trash it.
Just use it as is until you get a round tuit.

Another youtuber, posted this confirmation video (https://www.youtube.com/watch?v=htMqcGgDcXQ&ab_channel=AJRestorations)using BeyondBallistics' recipe.
I will have to give this recipe a try and bonus, it can be used with ultrasonic machine.

Suggest starting with 2/0 steel wool, after a few hour white vinegar soak —- then do another soak of a couple of hours and finish up with the 4/0 steel wool. Rinse and evaluate.
Best, Fred
It looks to me like transferred rust from whatever object was placed on top and not necessarily rust on the table top. And I don't think that we have established:
A) what type of metal
B) whether it has been painted or coated with something
The de-rusting process will vary depending on the metal and any surface finish, and whether PJ is dealing with actual rusting steel, or a stain from a rusting steel object left on top.
For example, if the surface is painted or coated, the rust stains could be superficial from whatever rusting object was left on top of it. Strong acid or solvent based products will damage the paint. In this case, aren't you supposed to use PH neutral product?
