I have just noticed this weird white scuff develop on my (I believe formica, or possibly laminate) countertop. What is strange is that when I wipe it with water it practically disappears! Then as it tries, it is hardly noticeable until *poof* its back an hour or so later. I don't know what it could have been caused by, I keep a spice rack and some metal containers of dried tea leaves close to their, and some dish soaps.. it is right beside the sink.
I'm trying to figure out how to remove the white mark, any thoughts or suggestions?
I have tried a baking soda + white vinegar mixture with no success.
It is probably a scratch from something rough and heavy being slid across the counter top. You can't wipe it off, but you may be able to repair it. Here is a link to a web site that tells you how to repair scratches in formica. Either click on the link or copy and paste it into your Google search field. Hope this helps. Good luck.
I have had a rent house that had ten year old counters and it had the same white mark. When I remodeled the house to down size into I added a new set of cabinets just opposite the ones with the ten year old counters in the same color. After cleaning the scratches and white stain off you would swear both counters were the same age. Use a cleaner called bar keepers friend and apply it with the magic eraser sponge. Clean the area with the spot and rinse and then dry. Finally, use a Formica counter top polish and it will look like new.
