Will your Sandstone Cleaner remove oil and tar stains?

Our Sandstone Cleaner is water based and, while it is a degreaser and will certainly work on residual stains, it will not work as effectively on major spills as MASONRY CLINIC’s Oil, Grease & Tar Remover.

Do you recommend your Sandstone Cleaner for organic growths such as mould moss and algae?

Certainly or Sandstone Cleaner will remove such contaminants, but for the most powerful anti-bacterial and long term treatment of hard surfaces we suggest MASONRY CLINIC’s Patio, Path & Wall Fungicide. It works like magic!

How much MASONRY CLINIC Sandstone Cleaner do I need?

Much depends on the degree of soiling but, as a yard of thumb estimate, a litre will clean around 9 square metres (or 97 square feet).

What are the main things that can be removed with your product?

Dirt of all kinds can be cleaned with Sandstone Cleaner including everyday dirt and grime, residual oil, and all kinds of food and animal stains.

What surfaces can your Sandstone Cleaner be used on?

Our product has been specifically formulated for sandstone walls, flooring and paving whether in slabs, setts or blocks – in rougher “rubble” or smoother ”ashlar”.

What is the main advantage MASONRY CLINIC Sandstone Cleaner has against competing products?

With an unbeatably effective bio-degradable formula our Sandstone Cleaner is safe, non-toxic, plant and animal friendly and, unlike others, is so safe it can be sprayed.

Why do I need to use cleaner specific to Sandstone?

Because different types of stone vary in their surface properties, particularly between sandstone and limestone, and are less consistent and more readily damaged than some man-made materials such as brick.

Is Sandstone Cleaner easy to use?

It certainly is – with a simple brush or with a pressure washer. After wetting the surface thoroughly the Sandstone Cleaner is applied generously with a brush, and washed off with cold water. Full directions are on the package.

Why do you call your MASONRY CLINIC Sandstone Cleaner “the world’s best”?

Because we keep an eye on all competing products around the globe and make sure that our formulas are at the cutting edge of scientific excellence. In fact, if any customer feels they have found a competing retail product that does the job better, sending us the used item with a note explaining why they feel it is better, we will refund their last purchase of MASONRY CLINIC Sandstone Cleaner made at any time in the previous six months!

Sandstone cleaner

Works ok needed to attempt to remove the stains several times to eliminate about 95 percent of the unknown stain while adding a bit more of the treatment as I was working it in with a scrubbing brush. The customer service was excellent.
