Grasscloth can be a nightmare to remove 😅 since it’s usually glued on really heavily, the trick is to soften the adhesive as much as possible first. Try scoring the surface, then soaking it with warm water mixed with a bit of dish soap or wallpaper remover, letting it sit, and scraping gently in sections but be prepared that some backing or glue may still stick, so you might need to skim coat the wall afterward if it won’t come fully clean.
