Hi everyone

we are a general/carpet cleaning company and have been asked to clean a house where the slate floor in the kitchen has been badly contaminated with urine. Can I have some advice please on products and methods to apply?
I am assuming I can use my Victor Sprite and a stripping pad? Any feedback much appreciated. Thanks

Most slate is not acid sensitive so no real problem here!

Just use some Aqua Mix High Alkaline Cleaner.  Use your Victor fitted with soft to medium scrubbing brush.

1.  Pre wet the floor
2.  Apply the HDT&G Cleaner and allow to dwell
3.  Agitate with brush
4.  Vac up and rinse then vac again check area
5.  If necessary repeat and add honing powder
6.  Once thoroughly dry seal with a topical or enhancing penetrating sealer

Any problems post back or e mail or call us

You may find that the salts in the urine need to be neutralised which an alkaline cleaner on its own cant do. They will eventually grow in the floor as they attract moisture again.

Something like Chemspec Urine Contamination Treatment will do this or their Kill Odor Plus or an enzyme based product again Chemspec Enzall. After the dwell time scrub and vac the areas then follow Kevin's method outlined above.

We maintain some offices with Burlington Slate in the washrooms and the urinal areas always pose a problem. They are well sealed but still need the above on the periodic visits as the cleaners only mop with detergent painting all around the floor.

Get yourself a UV Torch for when you do the sample and you can check (CSI style) to see if Kevin's method completely removes them or if you will need to increase the steps in the method statement to include use of a specific urine neutraliser first and then quote accordingly.
