The short answer
Should you bathe with antiseptic before surgery?
Have a bath or shower with ordinary soap the night before or on the morning of surgery, unless your team gives you a special antiseptic wash. If they do, use it exactly as written. Do not buy a strong antiseptic liquid on your own and pour it into your bath water.
Why a bath matters
Most wound infections after surgery come from germs that already live on your own skin. A good wash lowers the number of germs near the area of the operation. In theatre the team then cleans the skin again with an antiseptic just before the first cut. Your bath and their cleaning work together.
Plain soap or antiseptic?
For most operations, plain soap and water is what guidance such as NICE recommends. Some hospitals give a chlorhexidine body wash, an antiseptic soap, for certain operations or for people who carry particular germs on their skin. Either way, follow your own hospital's sheet.
Who needs a different plan
If you have an open wound, a stoma, a skin condition such as eczema or psoriasis, or you cannot get into a bath or shower safely, tell the team. They may give you a different plan, or have a nurse help you wash on the ward.
If you are coming from a district town
A long bus or car journey on the morning of admission can undo a fresh bath with sweat and dust. If you travel the day before, bathe where you stay that night, change into clean clothes in the morning, and carry a small soap and fresh towel in case the ward lets you wash again.
At home
How should you bathe before the operation?
Use clean water and a fresh towel
Use a clean bucket and mug or a shower. Use a towel that has been washed and not used by anyone else since. Wash your hair first with your normal shampoo.
Wash from top to bottom
Soap your whole body, working down from the neck. Pay extra attention to the armpits, groin, belly button, skin folds and under the breasts, where germs collect. Rinse well.
If you were given an antiseptic wash
Use it in place of soap, on a wet cloth, as your sheet says. Keep it away from your eyes, ears, mouth and genitals. Rinse off fully, and stop if your skin burns or itches.
Dry and dress in clean clothes
Pat dry with the fresh towel. Put on freshly washed, loose clothes, and sleep on clean sheets the night before if you can. Do not put anything on your skin afterwards.
Not sure whether this applies to you?
Ask an oncologistAfter the bath
What should you avoid putting on your skin?
Many everyday products stick to the skin and make it harder for the antiseptic in theatre to work, or react with the equipment.
Oils and creams
Coconut oil, body lotion, moisturiser and hair oil leave a film on the skin. The theatre antiseptic and the sticky dressings do not work well on oily skin.
Includes
- Hair oil massaged in the night before
- Vaseline on the body
Powder and deodorant
Talcum powder, deodorant and perfume can irritate skin after an antiseptic and interfere with the pads the team sticks on your body during surgery.
Make-up, henna and nail polish
The team checks your lips, face and nails for colour during and after the anaesthetic. Make-up, kajal, mehendi on the nails and nail polish hide these signs.
Home remedies on the skin
Turmeric paste, herbal pastes and home ointments on or near the area of the operation can irritate the skin. Wash them off and leave the skin bare.

Commonly believed
What do people get wrong about washing before surgery?
"Scrub the area hard until it is red."
Hard scrubbing makes tiny breaks in the skin where germs can settle. Wash gently with soap and your hands or a soft cloth. Clean skin is the goal, not sore skin.
"A stronger antiseptic is always better."
Strong household antiseptic liquids can burn or dry the skin, and irritated skin is more likely to become infected. Use only what your hospital gave you, in the way it was explained.
"Shaving the area at home helps the doctors."
Shaving with a razor leaves tiny cuts that raise the chance of a wound infection. If hair needs removing, the team does it with clippers, close to the time of surgery.
"If he is too weak to bathe, it does not matter."
It still matters, and help is available. A family member can give a careful sponge bath at home, or ward nurses can help after admission. Tell the team if bathing is difficult.
Did you know
Stopping smoking and keeping blood sugar under control both help a wound heal and resist infection, as much as anything you put on your skin. Ask your team about both well before the operation.
Being straight with you
What can this page not tell you?
It cannot tell you which wash your own hospital uses, or how many times to use it. Some centres ask for one wash, others for washes on more than one day, and some give none at all. Your written sheet decides.
It cannot remove every risk of infection
Careful washing lowers the chance of a wound infection. It cannot make that chance zero. Things like the type of operation, diabetes, smoking, weight and a long operation all play a part, and some wound infections happen even when everything is done right.
Tell the team about allergies
If you have ever reacted to an antiseptic, a soap, sticky plaster or iodine, tell the team at the fitness check. There are other options, and they need to know before theatre, not after.
What to watch for after surgery
Redness spreading around the wound, pus, a bad smell, or a fever once you are home should be reported to the team the same day.
Questions we are asked
Common questions about bathing before surgery
Should I bathe the night before or the morning of surgery?
Either is usually fine, and your sheet may name one. If you have an early admission and a long journey from a district town, a bath the night before is often easier. Wear clean clothes afterwards and sleep on clean sheets. Some hospitals ask for a bath at both times.
Can I use Dettol or Savlon in my bath water?
Do not add a household antiseptic liquid unless your team has told you to. These can dry and irritate the skin, and irritated skin can raise the chance of infection. Plain soap and water, or the specific wash your hospital gives you, is what you need.
What is a chlorhexidine wash?
It is an antiseptic body wash that some hospitals give before certain operations. You use it on a wet cloth in place of soap, keep it away from your eyes, ears and genitals, and rinse it off fully. Stop using it and tell the team if your skin becomes itchy, red or swollen.
Can I oil my hair the night before?
It is best not to. Oil spreads onto the face, neck and pillow, and leaves a film that makes skin cleaning and sticky pads less effective. This matters most for head, neck, face and upper body operations. Wash your hair with normal shampoo and leave it free of oil until after surgery.
I have a skin rash near the operation site. What should I do?
Tell the surgical team before admission day, and show it to them. A rash, boil, cut or fungal infection near the area can raise the chance of a wound infection. The team may treat it first, or decide the operation can go ahead as planned.
Is it all right to use deodorant?
Leave it off on the day of surgery, especially for breast operations or anything involving the armpit. Deodorant and talcum powder can irritate skin that has been cleaned with antiseptic. You can usually go back to it once the wound has healed, but ask the team first.
Does the team wash my skin again in theatre?
Yes. Once you are asleep or numb, the team paints the skin over the area of the operation with an antiseptic solution and covers the rest of the body with sterile sheets. Your bath at home comes first. It does not replace this step.
Can I wear my mehendi or nail polish?
Please remove nail polish and false nails, and avoid fresh mehendi on the hands and nails. The team uses a clip on the finger to measure oxygen and also watches nail colour. Dark polish or henna can make those readings less reliable during the anaesthetic.
