A guide to efficiently locating marked bills early in Cash Cleaner Simulator.
Cash Cleaner Simulator: Marked Bills Guide
Note: This guide only covers sorting Dollars and Euros. For Yen, you’ll need the Money Counter XXL (¢6000).
This is my streamlined large-scale setup for quickly sorting mixed currency and identifying counterfeit bills. While you can expand it for more efficiency, this is the minimum setup required. To maximize usefulness, make sure you have an active quest that asks for counterfeit or marked bills—this allows full use of the scanner feature.

Counterfeit Sorting Setup

- Set up the sorting table (see reference image).
- Feed dollar-heavy piles into the Money Counter Euro L.
- Feed euro-heavy piles into the Money Counter L (dollars).
- Set both machines to no denomination filtering, with bundles of 100 bills.
Sorting Behavior:
- The Euro sorter spits out Dollars into the front Cardboard Box XXL.
- The Dollar sorter spits out Euros into its front Cardboard Box XXL.
- Counterfeit bills are automatically ejected to the side, onto the Plastic Pallets.
Both machines can detect counterfeit bills in both Dollars and Euros. As a result, your Cardboard Boxes will only contain legitimate bills, whether marked or unmarked.
Best Spot for the Standing UV Lamp
Optimal UV Lamp Placement & Marked Bill Detection Strategy

The UV Standing Lamp is essential for detecting marked bills—but it works best at night. During the day, red markings are much harder to see, so I highly recommend reserving marked bill sorting for nighttime sessions. It’s still doable during the day, just significantly less efficient.
Recommended Setup: Buffer Boxes for Safety
Place two XXL Cardboard Boxes near the UV lamp. These serve as buffer zones to avoid contaminating your clean, unmarked bills.

- Left XXL Box: After sorting and cleaning a batch of bills, place them here temporarily.
- Scanner Use: With a quest active that requests counterfeit/marked bills, scan the bills in the left box.
- The scanner will only detect marked bills at this stage (since counterfeit ones were removed earlier).
- If the scanner shows no checkmark, transfer everything from the left box to the right box, ensuring only clean, unmarked bills are stored.
This step prevents marked bills from sneaking into large stacks and saves you the pain of re-sorting everything.
Why Sort at Night?

- Marked Bills: Much easier to see under UV light at night due to better contrast.
- Counterfeit Bills: These can be sorted during the day using the Money Counters and setup from the previous guide.
In my process, I only sort marked bills at night to make spotting red markings easier and avoid mistakes.
Final Marked Bill Sorting Setup

- Use the Money Gun to lay bills flat in a well-lit area around the UV Lamp.
- Visually scan for red marks.
- Use the two XXL buffer boxes:
- One for freshly cleaned bills pending scan.
- One for verified clean bills, free of both counterfeit and marked tags.
Why All the Extra XXL Boxes?
Because I like to do all my sorting in bulk over a day or two, I also keep:
- A dedicated XXL box near the UV lamp at all times.
- Additional XXL boxes for each denomination and increment, so bundling and wrapping later is fast and organized.
Marked bill detection was the slowest and most tedious part of the game for me—this system made it much smoother. Hopefully, it saves you the same headache!
