If the impregnator has not been on the surface for more than 24 hours, use a bit of the impregnator itself to reactivate the residues.

If the impregnator has been on the surface for several days, use Lithofin WAX-OFF, let it work for 10-25 minutes (scrub occasionally). Then rinse off thoroughly.

Apply Lithofin WAX-OFF undiluted and allow it to work for 5-10 minutes. Add some water, brush, and then remove the product. Rinse thoroughly with clear water. You may have to repeat this procedure.

In case of stubborn, deep-seated stains apply Lithofin OIL-EX in a 2 mm thick layer to the dry surface and cover it with some foil. Remove the foil after about 12 hours and brush off the white powder after one more hour.

The impregnator has probably been applied to a still moist surface. Remove the protective treatment with Lithofin WAX-OFF. When the surface has completely dried, reapply the impregnator Lithofin STAINSTOP >W<.

Product residues were not removed in time and have dried on the surface. These dull areas can be removed with Lithofin WAX-OFF and a white nylon pad.

Put some Lithofin WAX-OFF (undiluted) on the spot. Allow the product to work for 10 to 15 minutes, brushing occasionally. Then rinse the surface with plenty of clear water.

Lithofin MN Colour Intensifier has probably been applied too generously. The stone could not absorb the quantity of product and the product residues formed puddles which dried on the surface.

This surface film can be dissolved with Lithofin MN Colour Intensifier. Simply reapply the product and ensure an even distribution. After 5 to 10 minutes, remove all surface residues with a dry cloth. The colour intensifying effect and the impregnator’s effectiveness remain intact.

Alternatively, you can remove the impregnator entirely with Lithofin WAX-OFF. Apply the product with a brush and allow it to work for 15 to 20 minutes scrubbing occasionally. The rinse the surface with plenty of clear water.
