Rust on flag stones
« on: April 12, 2014, 12:03:56 pm »
Whats the best product for getting rust of paving? Stains left from barrell type flower pots just got circles of rust which I couldnt remove. Lee has told me Tensid do a product but just want any other suggestions or any tips?
Paving is flag stones but old and really weathered.

You need an Acid solution that will act as  a chelating agent for metal cations . This will dissolve rust staining from concrete surfaces.
We could carry out this process for you... if you do not feel confident of not damaging the concrete.
I take it you did not want to pay tensid prices?

Cheap option is soak then apply well diluted Hydrochloric Acid, this will take the rust almost immeddiately so rinse after about 20 seconds. Repeat as required, increase strength as required. I'd start about 4 part water.

Tesid will be Safety Clean. Great product, a genuine acid alternative. Use in the same way but less likely to damage anything.

Tensid offer samples, might be just enough for waht you need then try both.

Depending on the colour of the paving slabs you could use either Citric acid or Oxalic acid .
Any chance you can put up a photo of the staining?

Thanks for the replies I think I will try oxalic acid. Tensid a bit expensive for me.
Never took any photos while I was there. They are 2x2 yellow flags, really weathered.

That is oxalic acid.

Chris

No that is one of the ingredients in it.  It is a little more complicated than just a buffered acid.

Buffer solutions stop PH levels having pre menstral mood swings when acid or alkali's are in the mix .  ;D
They remove hydrogen ions or hydroxide ions...with those bad boys gone things remain stable.
