Question

We have been asked to clean the ceramic floors, ceramic tile walls, and freezer floors, in the food prep area in the restaurant in the airport. There is a catch - a two hour turn around time, between lessees, in which to accomplish the task. The area is about 40 x 60 with a number of tiled walls dividing food prep areas. We can do this, but were wondering if there was a good cleaning product on the market that could be used to remove the grease buildup up quickly in the food prep environment? Also, one of the freezers floors is badly worn and rusted and needs some TLC. Any ideas on what would be the best products to use on this?


Answer

If you have access to a truckmount with high temperature water and a hard floor tool, this should go quickly. Where needed, apply any properly diluted degreaser, let it sit for a bit, and then rinse the floor with hot water at about 1200 psi. The hot water will clean the freezer floor nicely, even the rusted areas. The vacuum will leave the floor dry, but the rusted areas will not improve in appearance, nor should anyone expect that.
If you cannot go with this, use a rotary floor machine with a scrub brush to work in the degreaser and pick up with a wet vac. Rinse and pick up again.
The walls can be presprayed and rinsed at lower pressure with a pickup device nearby to collect the solution. Use a squeegee to avoid water spotting the tile.
With the short time you have to work, you may have to make a number of visits. It all depends on the tools at hand and the size of your crew.
