The bacteria are not visible to the naked eye, so you immediately forget that the bacteria lurk anywhere in the home. You should not be surprised that especially the bathroom and kitchen can be a good breeding ground for bacteria. Don't worry, of course, not all of these bacteria are dangerous. However, some can cause illness in you or your family. If some bacteria find the right nutrients and a suitable environment, they can double in every 20 minutes by division.
This also explains why disease symptoms appear shortly after contact with dangerous bacteria. Regular and effective cleaning with the right cleaning and disinfection products can help protect you and your loved ones against pathogenic bacteria like those mentioned above.
