Ashoka Restaurant - 23/Feb/2010 As part of a major refurbishment and upgrade we were asked to clean the natural slate floor in the restaurant area. The floor required a really deep clean due to food spillages etc, this was carried out using a mild detergent and a rotary scrubber with the cleaning agent being allowed to dwell for a considerable time.<br />After the floor was fully cleaned a water based sealer was applied to protect the slate from future abuse.
