Hi Jan
The white scourer is NON-SCRATCH. We also use these on stainless steel sinks etc.....they come up a treat. Ask your local cleaning supplier about them.
Besides, laminate flooring is just a photograph of wood grain, and using these scourers will do no damage especially if used lightly.
Infact, i have used the ordinary scourers with white spirit to remove glue from old tape marks from NEW laminate flooring without scratching.....much. However, I would not recomend using those type on the flooring, but would the NON ABRASIVE ones.
Thanks for having faith in me Jan

Regards
Tim
P.S I was thinking just the other day that there are not many of us left on the forum that were here when I started about 15 months ago.....only a few old favourites left. Most are newbees.
