Hi there,

You can buy this product inexpensively, online. 
Follow these steps :

Apply and evenly distribute Lithofin MN Power-Clean diluted up to 1:10 and wipe the surface.
In case of stubborn dirt deposits, apply undiluted or diluted up to 1:5 with a brush and distribute. 
Allow the product to work for approx. 15 minutes; brush occasionally. 
Do not allow to dry; add water if necessary. 
Brush again before wiping up. On large areas, use a squeegee to remove the product. 
Wash the surface thoroughly with clean water. If the result is not satisfying, repeat the process allowing the product to work longer and
brushing more vigorously.

I hope it helps.

Hi .. Clean stone surfaces with a neutral cleaner, stone soap, or a mild liquid dishwashing detergent and warm water. Similar to any item cleaned in your home, an excessive concentration of cleaner or soap may leave a film and cause streaks

you can use a hot wash and then seal it with storm dry you will never have that problem again it's the best sealant for that I always use it and its amazing stuff but if the hot wash don't get it off there's a chemical you can use then you seal it after its been washed I hope that helps you
