If necessary make keeping your surroundings clean and helping with chores, rules. If they must be rules, there must be consequences for not obeying them. Parents have a right to certain expectations of those who live under their roof. Non- compliance should mean consequences. Although chores should be done properly, I feel expectations should be reasonable.
Teens are notorious for cutting corners.
You must admire their creativity in this respect, while encouraging them to improve in technique. Please, no white glove test. Remember, this is your home not a hospital, and these are your kids, not a hired maid. If you feel you must pay them for these jobs then require a more thorough job. If it is an extra task above and beyond their usual chores, standards should be much higher.
