Interview with Prof. Dr med. Alexander Herold
What form of cleaning would you recommend?
For me the answer is clear: clean water – hot or cold – is always the most effective and gentle way. You should stay away from bleached, perfumed or colourful toilet paper, since these can contain allergens. I would also advise against using wet wipes as well. The preservatives which keep the paper durable as well as the substances used to ensure they stay moist can pose a hazard to people who have allergies.
What disadvantages are there to cleaning with water?
There aren't any. With water, your bottom is cleaned thoroughly, and the cleaning is also gentle to your skin. So water is by far the most hygienic cleaning agent.
