The basics are simple: wash gently with plain water or a mild, unscented soap after every bowel movement, and pat dry. But most people either overdo it or underdo it, and both create problems. Here’s what actually matters for keeping things clean, comfortable, and irritation-free.
The Step-by-Step Process
After a bowel movement, clean the area with wet toilet paper, a damp washcloth, or a bidet. Plain water works well on its own. If you use soap, choose an unscented bar like Dove and use as little as possible. Scrubbing is unnecessary and counterproductive. The skin around your anus is thin and sensitive, so a gentle wipe or rinse is all it needs.
If you have a vulva, wipe or wash from front to back to avoid dragging fecal bacteria toward your urethra. That said, the key principle is simply not smearing feces forward. You don’t need to be obsessive about it. The American College of Obstetricians and Gynecologists doesn’t even include wiping direction in its UTI prevention guidelines, and fecal bacteria are already present in the surrounding environment regardless.
Drying matters more than most people realize. Residual moisture against the skin creates a warm, damp environment where fungal infections thrive. After washing, let the area air-dry if you have a moment, pat gently with a soft towel, or use a hair dryer on a cool setting. Don’t rub.
Why Over-Washing Causes Problems
One of the most common causes of chronic anal itching, known as pruritus ani, is actually cleaning too aggressively. Scrubbing with rough toilet paper, using hot water, or applying soap every time you wipe strips the natural oils from the skin and causes micro-abrasions. The result is a frustrating itch-scratch cycle where the irritation makes you want to clean more, which makes the irritation worse.
If you’re dealing with persistent itching or redness, try scaling back. Skip the soap entirely for a week, switch to water-only cleaning, and avoid scrubbing. The symptoms often resolve on their own once the irritation source is removed.
What Products to Avoid
Skip anything scented. That includes scented soaps, bubble bath, body wash with fragrance, talcum powder, and deodorant sprays marketed for “freshness.” These products contain chemicals that irritate sensitive skin and serve no hygienic purpose.
Flushable wipes deserve special caution. Many brands contain a preservative called methylisothiazolinone, which is a well-documented allergen. A study published in JAMA Dermatology found that this ingredient causes allergic contact dermatitis around the anus and perineum, sometimes severe enough to be misdiagnosed as psoriasis. About 3% of people tested show an allergy to this compound. If you’ve been using wet wipes and notice redness, itching, or a rash that won’t go away, stop using them. In documented cases, the dermatitis resolved completely once the wipes were discontinued.
If you prefer a wet wipe, look for ones that are fragrance-free, alcohol-free, and free of preservatives like parabens and sulfates. Or just dampen plain toilet paper with water.
Bidets vs. Toilet Paper
Bidets clean more effectively with less irritation. A 2021 study in the Journal of Water and Health found that bidet use reduced fecal contamination on the hands compared to toilet paper alone. Water rinses away residue without the friction that dry paper creates, which is especially helpful if you’re prone to hemorrhoids, fissures, or general sensitivity. Dry toilet paper can cause tiny cuts and chafing over time, particularly with cheaper, rougher brands.
You don’t need an expensive built-in bidet. Attachable bidet seats start around $30 and connect to your existing toilet. A handheld spray nozzle or even a squeeze bottle with warm water works fine as a budget alternative.
Cleaning With Hemorrhoids or Fissures
If you have hemorrhoids or an anal fissure, standard wiping can be painful and slow healing. Use soft, alcohol-free wet wipes or rinse with a bidet or shower instead. Cleveland Clinic recommends sitz baths two or three times a day for 10 to 15 minutes. This is just sitting in a few inches of warm water, either in a bathtub or a small basin that fits over your toilet seat. The warm water relaxes the muscles around the anus and soothes inflammation without any products.
Avoid rough toilet paper entirely during flare-ups. If a bidet isn’t available, dampening soft toilet paper with water before wiping is a good alternative.
Leave the Inside Alone
External cleaning is all you need for daily hygiene. Internal rinsing with enemas or douches is not recommended for routine cleaning. The lining inside your rectum is far more delicate than external skin. It burns easily (water temperatures comfortable in a shower can damage it internally), and hard nozzles can cause tears that increase infection risk. Frequent douching with tap water can also disrupt your electrolyte balance.
If you’re considering internal cleaning before sexual activity, that’s a separate topic with its own safety considerations, but it’s not part of standard hygiene. Your rectum handles waste removal on its own.
How Often to Wash
Clean the area after every bowel movement and once before bed. That’s it. You don’t need to wash it during every shower beyond a quick, gentle rinse. Fecal residue left on the skin for extended periods causes irritation and inflammation, which is why post-bowel movement cleaning matters most. But washing more than necessary, especially with soap, creates more problems than it solves. Harvard Health Publishing notes that prolonged contact between fecal material and skin can invite infection and compromise the function of surrounding muscles, so prompt, gentle cleaning after each bowel movement is the priority.
