An unmolested piece of non woven wallpaper as it comes off the roll.
The stop watch is set at zero and we begin by pouring a cap full of Shop Rite's canola oil.
At 5.8 seconds on the clock you can see that the canola oil has already started to darken the NW material.
At 32 seconds I flipped the sample over to show that the oil is already though the back side and exhibits mottled staining.
This piece of wallpaper is completely destroyed in less than one minute. This greasy oil stain cannot be cleaned any more than you can get a gravy stain out of a silk tie.
