In *Kingdom Come: Deliverance 2*, the side quest "A Good Scrub" from Betty at the bathhouse in Kuttenberg's southeast part sets you on a path to more bathhouse-related tasks. After speaking with the innkeeper about work and heading to Betty's bathhouse, she sends you to Grund to fetch Matsek and the girls he's supposed to bring back as employees. You'll find Matsek in a courtyard, where you'll meet the girls and escort them back to Kuttenberg.
Once the girls are settled, Betty asks you to promote the bathhouse by shouting its praises at the grain market, horse market, vintners' street, and merchants' street during the day. After successfully promoting the bathhouse, you need to clean it up before the alderman's inspection. Completing these tasks on time is crucial to keep the bathhouse open and unlock the subsequent quest, "Ill Repute."
After the bathhouse passes inspection, Betty shares that the council is deciding on the city's main bathhouse. Your task is to make the councillor leave the competing bathhouse. Start by talking to Meaty Mary, Katcha, and Little Lida to learn what the councillor dislikes. You'll need Chamomile Brew to add to the wine cask on the second floor of the competing bathhouse. To get information from Lida about the councillor's preference for fragrant oils, you'll need to give her a noblewomen's dress from a tailor. If you choose to sabotage, head to the third floor, lockpick a cabinet, and steal the oils.
Katcha mentions that the bathhouse once had fleas. To find the flea-infested item, head to the east gate of Kuttenberg City. There, you'll find a small camp of beggars. Search the sacks to locate a flea-infested blanket, which is the hardest item to acquire for this quest.
Once you have the fleas, return to the bathhouse and go to the room where you added the Chamomile Brew to the wine. When no one is watching, interact with the baskets and pour the fleas into Councillor Naaz’s laundry basket and the clean laundry basket. If you can't find the flea-infested item, remember that completing just one of the three tasks can make the councillor leave, allowing you to finish the quest and proceed to others like "Axe from the Lake."
