Cuts and scrapes: cleaning, covering and recognizing wounds needing care
On this page
A cut breaks the skin; a scrape or graze rubs away its surface. A wound that looks small can still contain dirt, involve deeper structures or have come from a bite. Its depth, cause, bleeding and contamination matter more than calling it a minor injury.[1]
Terms and practical distinctions
Cleaning comes after controlling manageable bleeding
AAD advises washing hands, gently washing a minor cut with mild soap and cool or lukewarm water, and applying pressure with clean gauze or a cloth for bleeding. A clean wound can be kept moist with petroleum jelly and covered with a sterile bandage, changed daily. This guidance concerns a minor skin injury; it is not a method for closing a deep wound or extracting an embedded object. Petroleum jelly supplies a moist barrier rather than an antibiotic treatment.[2]
Handle the wound-facing surface carefully
St John Ambulance recommends rinsing a graze with clean water, avoiding rubbing, and patting the surrounding area dry with clean gauze. Its dressing advice emphasizes protection with a sterile dressing or plaster. Holding a pad by its edges helps avoid contaminating the surface touching the wound. Dirt that will not wash away, an embedded foreign object, a bite or suspected infection changes the situation from ordinary cleaning to medical assessment. Repeated scrubbing is not a substitute for removing deeply trapped material safely.[5]
Evidence & uncertainty
Cleaning recommendations and comparative cleaning trials answer different questions. The selected review concerns varied wounds and solutions, while first-aid guidance also addresses bleeding, debris, covering and situations that need professional care. It does not establish one complete home-care routine as superior.[4]
Selected-source overview · Independent review pendingPublished questions
Does uncertain evidence about tap water mean a scrape can be left dirty?
Selected-source overview · Independent review pending. Read the evidence context.
No. Comparative trials have uncertainty about which cleaning liquid performs better. First-aid guidance still recommends cleaning a minor wound and seeking help for dirt that remains trapped.[4]

Can antibiotic cream replace tetanus vaccination assessment?
Selected-source overview · Independent review pending. Read the evidence context.
No. CDC does not recommend antibiotics to prevent tetanus. Wound type and vaccination history determine the separate prevention assessment.[3]

Why is petroleum jelly used on a clean minor cut?
Selected-source overview · Independent review pending. Read the evidence context.
AAD recommends it to maintain a moist healing surface under a covering. It is a barrier product, not an antibiotic and not a way to close a deep cut.[2]

Should an embedded piece of glass be pulled out at home?
Selected-source overview · Independent review pending. Read the evidence context.
No. NHS identifies an embedded object as a reason for emergency assessment and advises leaving it in place.[1]

Is a scar the same as a scab or an open scrape?
Selected-source overview · Independent review pending. Read the evidence context.
No. A scar is repair tissue after deeper injury. The open wound and later scar represent different stages and need different interpretation.[6]

Which part of a sterile dressing should be kept untouched?

Keep the part that will touch the wound clean. Hold the pad by its edges and avoid rubbing the injured surface.[5]

Tap-water comparisons leave important uncertainty
The 2022 Cochrane review included thirteen randomized studies and 2,504 adults and children in community and clinical settings. Eight studies compared tap water with saline. Evidence for infection, healing, costs and patient experience was mostly low or very low certainty because studies were small or had design limitations. The review excluded burn and dental studies. Uncertain comparative results do not prove the liquids equivalent, and do not imply that wound cleaning itself can be skipped. The trial populations and wound types varied.[4]
Tetanus protection is a separate decision from antibiotic ointment
CDC’s clinical guidance distinguishes clean, minor wounds from dirty or major wounds, including punctures, bites, wounds containing soil and injuries with devitalized tissue. A clinician assesses wound care, vaccination history and whether tetanus immune globulin is indicated. CDC explicitly advises against topical or systemic antibiotics solely to prevent tetanus. Treating an actual wound infection is another indication. A rusty appearance alone therefore cannot select the needed protection, and applying an antibiotic cream cannot replace checking vaccination history.[3]
Healing appearance does not identify infection by itself
AAD explains that injury limited to the outer skin can heal with new skin, whereas deeper injury can leave a scar. Scars may change color and appearance over time, and raised scars have different forms. Its prevention advice favors gentle cleaning and cautions against hydrogen peroxide, which can damage healing skin. The injury’s depth and the later repair tissue help explain why healed areas can look different. Scar appearance is a later outcome rather than the definition of an open scrape.[6]
Some warning signs require urgent or emergency assessment
NHS advice calls for urgent assessment of bites, persistently dirty wounds, increasing pain, swelling, redness, pus, fever or feeling unwell. Emergency care is needed for bleeding that will not stop, spurting blood, loss of feeling or movement, a very large or deep wound, a serious face or palm cut, or an embedded object. Leave an embedded object in place. These are UK escalation routes; elsewhere use the local emergency service or urgent clinical service.[1]
