Ash Settings

When laser cleaning Ash, start with controlled power levels to leverage its strong laser absorption, which removes surface contaminants efficiently without deep penetration. This property works well because Ash's open structure allows heat to spread evenly, restoring wood grain in applications like furniture refinishing or heritage pieces. Make sure you adjust scan speeds slower during initial passes, as the material's moderate density can lead to uneven heating if rushed—watch for charring on porous areas. Reduce overlap ratios to avoid overexposure, revealing clean surfaces while preserving the wood's natural flexibility for further handling.
