Direct answer
The checked current Sandustry building index does not list a Sand Washer or Seed Washer. For the search intent, use a Wet Sand production layout: combine Sand with controlled Water, route the resulting Wet Sand into a Shaker, and design clear paths for Residue and Gold.
Field note
Correct the machine-name assumption
Do not spend resources searching for an unsupported washer building based on a community page. Check the current official building index and the in-game research interface before accepting an entity name.
The durable current chain is Sand plus Water into Wet Sand, followed by Shaker processing.
Field note
Build a controlled Wet Sand feed
Introduce Water to Sand in a small, observable area. Prevent excess Water or unrelated material from reaching the Shaker and leave a way to stop the feed without flooding the downstream section.
Confirm the resulting material identity before scaling the chamber or adding automation.
Field note
Connect the Shaker outputs
Feed Wet Sand to a Shaker layout that allows Residue to move away and Gold to remain recoverable. A descending diagonal arrangement can help the slow output clear.
If the chain stops, diagnose Water control, material identity, feed depth, and output capacity; do not invent a missing washer upgrade as the explanation.

What this page does not claim
- No Sand Washer or Seed Washer appears in the checked current official building index.
- This page must be revised if a future official update adds a machine with that name.
