How to use Rob Parker’s Best Rust Remover

Rob Parkers Rust Remover will remove rust stains from stone paved surfaces.

Rust stains can be caused by a number of reasons.

To ensure you achieve great results using our product please read these guidance notes.

What causes rust staining on stone paving?

Naturally occurring rust deposits within Indian grey sandstone sometimes leach to the surface of the paving.  These natural deposits are sometimes brought to the surface whilst the patio is laid, when harsh chemicals such as brick acid have been used. (We do not recommend brick acid on any natural paving- try our Conclear, a much gentler but still effective product)

Grey sandstone from some sources seems to suffer more from these deposits than others. Our own grey sandstone doesn’t suffer so much as others we have heard of.  Wherever you have bought your grey sandstone from, rest assured your patio can be restored, by using Rob Parkers Rust Remover. Customers who have experienced rust staining on Kandla grey sandstone  report great results using our product.

Rob Parkers Rust Remover will also remove the tannin stains that sometimes occur on imported Indian sandstone.  These stains are caused by the transportation crates that the paving has been shipped in.

Rust deposits can also occur from metal garden furniture being left on the surface, and beginning to rust.

Moss killing lawn feed is made from ferrous sulphate.  If it is accidentally spilt on the patio, and then reacts with dew, iron spots will appear on the patio.

Rob Parkers Rust Remover can address all these problems.

For best results using Rob Parker’s Best Rust Remover:

We suggest you try a test area first.  Find a stained slab and try different concentrates until you find the most effective for you.  Effervescence will occur when the rust is being treated.

Work a small area at a time

Apply to small areas at a time, up to 5 sqm at once. (As a guide 1Litre will cover 3-5sqm, but this is dependant on the severity of the problem)

By working on a small area at a time, you will be able to manage the activation process, if you try to work over too large an area, evaporation will begin to occur and activation will cease.  You can aid the prevention of evaporation by covering the surface with plastic if necessary.

Apply product to dry surfaces

The product is very liquid and therefore free flowing.  This means it will go a long way, but care should be taken to only treat the required area.

Apply to dry stone areas to ensure the best activation of the product.

For best results apply with a paint brush; this will enable you to agitate  the surface as you apply ensuring excellent contact with the stone surface.

Once the selected area is covered with Rob Parkers Rust Remover, start again, repeating the above method, by either reapplying product if it has dried or agitate existing product thoroughly on the surface if still wet.

It is important to keep the area you are treating wet with product, as once its dried it is no longer active. Effervescence will occur when it is activated. Use as much as required to achieve the desired result.

Repeat again unless staining has disappeared.

Thoroughly rinse product off once desired effect has been achieved.

Be careful where product is used

Do not allow product to drip onto plants, clothing, skin, etc, as this is a mild acid that will burn.

Do not allow pets or children to use areas during active treatment.

Do not use on limestone or polished stone surfaces, as this product will burn the stone surface.

    Hi, I’ve recently treated a many areas with this rust removed with great results, however with one of my small paving slabs (grey sandstone ) it has left a grease mark / looks wet when its dry. There is a subtle grease residue left on the paving slab which might be causing it to appear wet?

    Any suggestions? Like i said, ive tried it everywhere else without fault and so I’m baffled to why this paving slab has come out differently?

    Most of my issues were rust spots, small areas on the slabs, but this particular slab (quite a small rectangle) needed to be covered in the rust remover.

    Appreciate any potential reasons for this? Could it be that I’ve left it on too long? In the meantime, I’ve recoated the slab with the rust remover and rinsed off quickly, I’ve then cleaned the slab with dish soap / hose? Currently waiting for it to dry.

      HI Oli, we are not sure what has caused this. Has your latest clean helped at all? Was the slab different in any way before the treatment began? Please send a picture of this issue to sales@stoneworld.co.uk if you require further help with this issue. We will try and help
