&nbsp;&nbsp;&quot;BERT/27&quot; Extra Strong Detergent<br>
&nbsp;&nbsp;This is an extremely concentrated, acid-based detergent for granite, ceramic or gres. It should only be used for strongly-resistant soiling or to eliminate rust or potassium nitrate. One of its great advantages is that it forms a layer of foam that does not drip when used on vertical surfaces, so it is especially useful for the deep cleaning of wall-tiles immediately after fixing. <br>
