Viral advice for keeping your underwear clean

“There are a number of possible causes for this, which may or may not be relevant to you…”

“First and easiest, look at the type of toilet paper you use at home (of course, you can't control what's available elsewhere). Some toilet papers have a smoother/slippery surface and are less efficient at removing any residue. Nasty brands aren't always the cheapest and often include those that are marketed as being “gentle” on your butt (they may have such a slippery surface that they glide over your skin with minimal friction and don't do their job properly). this has a slightly more textured surface to “grab” and remove.

Also, while still in the toilet paper area, make sure you wipe the entire perineal area, not just the anal opening. Sometimes the first few wipes can even spread the dirt to adjacent areas, and if you don't wipe those down, you'll likely end up with underwear stains.

But check with your doctor – it could be diet-related or due to an underlying medical condition.”
