3rd floor restaurant terrace access via restaurant and service elivator.
Terrace is white stone marble in style it's foam backed sitting on rubber spacers before the spacers sit on a membrane.
2years of grease and weather have left the slabs stinking.
We have no access to running water due to location so rotary scrub and power wash are out. So is the use of abrasive chemicals due to membrane and rubber pads any other options or is it scrub brush and hot water
Many thanks pics of kit be useful to
