The fact is that with the usual light, the kitchen looks absolutely clean, but the UV lamp showed the real state of affairs.
The author noted that he enjoys the kitchen about 8 years. After her study, the ultraviolet lamp he tried to wash the pollution, but he did not come out. Although it did not particularly upset him. He would just like to know whether such a number of spots is normal.
He also told how he did this photo. He put the camera on the table and put an excerpt for 15 seconds, after which he began to drive a flashlight with a UV lamp on kitchen surfaces.
The author noted that the wavelength should be 365 nm, otherwise such a contrast photo will not work.
