Small Black Dots On Floor

I take the tiny piles of black course dust and when removed it leaves what looks like a burn mark that is difficult to clean and take out of a nice box.
Small black dots on floor. The wax ring allowed water to seep between the two layers thus getting the top layer wet on the underside. When the new sheeting was put down the old one that was glued down wasn t removed. No one at work believes me. The rest of the apartment is hardwood so they.
Even experts say that removing the spots is virtually impossible scrubbing and scraping helps somewhat but you may end up doing damage to the surface and making things worse. Over the last two weeks black dots have appeared on many surfaces in my apartment. Carpet beetles are covered in tiny hairs which are difficult to see unless you look at them under magnification. Others might be mottled with spots of brown and black on a lighter background.
Even pressure washing doesn t work unless done right after the. My conservatory windowsills are full of little black dots every morning when i wipe them they are like tiny blood spots about 10 or so they go a bit of a dark red colour when wet. They look exactly like someone has taken a black pen and just done a cluster of between 20 30 dots. The brown to black spores are like tiny dots of tar that have been super glued where they land.
Bare wooden floorboards are a popular look but they need to be looked after. The homeowner told me the black spots appeared soon after the floor was resanded and had become increasingly worse. In the sink counters on some walls and heavily on the kitchen and bathroom floors which are linoleum and tile respectively. I know it wasn t ds as he.
When i ve swept the floor half of what i pick up are these dots there will be hundreds. Some are black or dark enough to appear black when observed with the human eye. It was not mold. Thanks for any further help.
Over the last 3 weeks i have found 5 clusters of black dots. So far i have found a cluster on ds1 s pillow on ds 1s bedroom floor lino on the hall floor laminate on the leather sofa and today on the cofee table. I recently came across a condition on a hardwood floor i had not seen in my 25 plus years as a consultant. I have also had this in other rooms on duvet cover photo frames ect.
I had a problem in our bathroom of black spots appearing on the linoleum. A red oak floor littered with tiny black and gray spots. This is also a problem with urine from pets or children. This is what caused the black spots.
