Pool Cleaning is a miscellaneous quest in Fallout 4.

Quick walkthrough

Miscellaneous Quest: Pool Cleaning
Talk to Sheng Kawolski.
In the water around his shack, pick up the 5 marked items.
Talk to Sheng Kawolski again.
Reward: 100/125/150/200 caps

Detailed walkthrough

The Sole Survivor can talk to Sheng Kawolski and bring up the question of if he has any work that needs doing. Sheng will explain that the source the town draws its water from needs to be cleared of debris and offers this task to the Sole Survivor, at which point they will have the opportunity to negotiate a higher payment for this service through Charisma checks (1st: CHR 8 to get 125 caps instead of 100, 2nd: CHR 8 for 150 caps, 3rd: CHR 9 for 200 caps). The job itself involves searching the irradiated pool for five marked junk items. Once completed, return to Sheng and claim payment for the work.

  • After paying the Sole Survivor, Sheng might also tell them that someone else tried to clean the water before them and that they were blown up by a grenade while on the job. This appears to be true given the presence of a skull in the water, which is also one of the marked items.


PCPC One of the objects may not be highlighted with a marker indicating to pick it up therefore making it only possible to pick up 4 of the 5 objects. [verified]

  • Reload a previous save prior to accepting the quest and entering Diamond City, then try again.
