It's hard to judge without a picture, but there is a situation that can cause you to do this, such as the problem with the primer spray in the first place. It's also possible that the furniture is moldy.
Wooden furniture: Mix a solution with a neutral detergent and water, a small amount of ammonia has been added to the water, and then use a cloth dipped in an appropriate amount of solution foam to wipe off the stains. Then scrub with a cloth soaked in water and finally polish or wax as soon as possible. >>>More
Try dipping a towel in gasoline, chloroform, xylene, ethanol, etc.
The best way to get your furniture ready to change color is to polish it. I've been doing furniture renovation for more than ten years.
The primer is not done well, the primer is not full enough, and the catheter hole is not filled, causing the paint to sink into the catheter hole to form a pothole.
There is a putty paste for professional furniture repair, apply some, and spray some self-spraying paint.
