Patio Rust Stain Removal Help

Not sure if this is the right group to post this in.....

I was spring cleaning the patio this morning, when I moved the bench - to reveal several rust stains . Now a quick dab of Hammerite will cure the rusty bits of the bench , but how do I remove the rust stains from the blue limestone patio pavers? Does anyone know of any off the shelf cleaner that can remedy this?
Mrs Smiffy is not well pleased as she told me to move the bench inside last October !
TIA

 

Oh dear Smiffy... :rolleyes:
Try a wire brush and white spirit or the stronger thinners used with the Hammerite.

 

Ozalic acid will shift it:

Thanks WiseOldOwl, Paladin ,Pro-Gard for the replies.
I was talking to a friend who works in the building trade - he said rust stains on slabs or stone are a nightmare to remove :eek: !
I'll try the white vinegar and thinners tomorrow weather permitting.
Pro gard the oxalic acid I can buy on Ebay

How do I apply this? You have used this before...

P.S. Anyone want to buy a bench with cast iron sides and inserts !!!!! It is deffo going on Ebay next week !

 

how about an old car mat (becsue its rubber) under each corner when it doesn't sell

 

Apply it as a solution rubbing it in with a scrubbing brush or mix it with some saw dust or similar and apply it as a poultice.

It does work but the dilution is best achived by starting weak and increasing the concentration until you shift it.

 

Thanks All for the tips....
I soaked the pavers with lemonjuice , and 10 minutes work with a wire brush has removed the stains!
The Oxalic acid tip from Pro-gard could be useful if you ever suffer deep staining. I gave my bench a coat of Hammerite this morning - I had already glued rubber to the feet to stop staining. So roll on BBQ weather

 

Well done smiffy
No how's about you pop over and rub this baby down and slap on a coat of green hammerite for me. :D

 

Paladin
My estimate is in the post to you !

A quick wire brush and then one coat of smooth white Hammertite , will make it look like new , that is a lovely cast iron seat.

 

Sad to say Smiffy,it's not cast iron. It's a cast alloy and as light as a feather. I'm going to gently burn off the white oil based paint and use a green hammerite to match my other benches.

 

But Nick, it`s already green. :D :D

 

Lovely seat Pal, We have this to strip and paint, dreading it, Ill wait untill you finish yours, then you can give us some tips..

 

Paladin , Daisy
Looks like a very fiddly and time consuming strip and paint - best of luck. You can get these things acid dipped - but as you say they are a zinc based alloy this may not be an option.
Daisy - what are them squigly things on your pic ?

 

So we can't get them dipped? B*ggar..
There metal Smiffy, stick em in the soil and grow sweet peas up, I dont know what there called, but you can buy them in GCs,..
