Got the broth to buy etc. to liberate my Kaercher Power scrubbing brush the grill terrace of fat. The Kaercher agent was me as opposed to this product too expensive. Since this product is advertised as a concentrate and can be diluted to 1:50, lt. Product description, I chose this concentrate. So now to the facts: Have the means UNVERDUENNT applied, leave on 20 minutes and then scrubbed the whole terrace above hardware. It was exhausting, but the terrace was largely clean. Now when you consider that I unverduennt auftrug the means and the power scrubbing brush (the thing is more Hammer) came into use, the remedies not a miracle cure and perspective my decision somewhat. Nevertheless 4Stars to the bottom line
