How to unlock the Mermaidman and Barnacleboy Unite! achievement in PowerWash Simulator - Definitive Guide

The sixth job in the pack. Plenty to clean. It took me about three hours to finish.

Find Patrick’s ID and clean it first for:

I get what you mean, this took forever. Feel like it took as long as the final main game level, The Palace.

There’s just so many little things you have to hit, like the Prison and Computer.

This is the final level and will take longer than all of the other jobs.

NOTE: This achievement and all the other achievements for finishing the levels, seem to be bugged in co-op. My friend hosted, and I had to replay them all while I hosted the game to get the achievements for finishing the level. Though the misc ones for cleaning specific things did all unlock in co-op on the first try.

I recommend going for this achievement

while you're here. I have a guide for that as well. If you miss it, you can go to freeplay and grab it as soon as you load in.

So for this job I recommend doing in co-op if you can, which will make the job go by way faster. Unfortunately the achievement is bugged, and will only unlock for whoever is hosting the game. The ID card achievement however should unlock regardless.

Use as many as the cleaning liquids with the soap nozzle as you can to get the larger areas like the glass ont he costume displays and the giant monitor.

A few areas that gave me trouble was the base for the monitor, and the weapon/gadget wall.

The monitor case has a few spots on the sides that tend to be hard to clean, so if you can't finish this piece, check there. The gadget wall makes you clean some dumb spots, like the inside of the gauntlet and one off the boots. Oh, and the controls on the Dirty Bubble prison can be tricky also. So clean them good.

Besides that, it is pretty straight forward minus the few small troubling pieces,

The Mermalair Job is the sixth and final unlocked in the DLC. You can check your to do list at anytime by pausing the game. You'll need to clean every item on the to do list fully to complete the job.

Make sure to complete the job specific It's Not My Wallet (30G) achievement on your first playthrough, so you don't have to play the level again.

The final job is the one that has the most intricate set pieces, nooks and crannies to clean. It also has a ton of fun lore from the show within the show, Mermaid Man and Barnacle Boy.

Make sure to find the tiny ID on the table next to the chemistry set and clean it first for It's Not My Wallet trophy_silver.png
