A white or light-colored outline along the edges or the top of the guitar bodyUpdated a month ago
Removing white residue from your guitar body before staining
Noticed a white or light-colored outline along the edges of your body during sanding, before you've applied any stain? Don't worry. This is almost always harmless surface residue left over from the sanding and manufacturing process, not a flaw, and not a different type of wood. In most cases it wipes away easily and won't affect how your stain or dye takes. Here's how to clear it.
What you'll need:
- A clean, lint-free rag
- Clean water
- Fine-grit sandpaper (for a light final sanding)
Step 1 — Wipe the area with a damp rag.
Lightly dampen your clean rag with water and gently wipe along the edge where you see the white residue. Don't soak the wood, just enough to wet the surface. This lifts loose residue and, as a bonus, raises the grain, which is a step you'd want to do before staining anyway.
Step 2 — Check the edge.
In most cases the white simply wipes away and reveals wood underneath that matches the rest of the body. If it's gone, you're on the right track.
Step 3 — Let it dry fully.
Give the body plenty of time to dry completely before doing anything else. Wet wood won't sand or stain properly.
Step 4 — Light final sanding.
Once dry, the raised grain will feel slightly rough. Do a light sanding with fine-grit paper to smooth it back down. This leaves you with a clean, even surface ready for finishing.
Step 5 — Grain fill (recommended for mahogany bodies).
Mahogany is an open-grained wood, so applying a grain filler before you stain gives you the most even, professional-looking finish across the whole body, including that edge. A tinted filler works well if you want to deepen the color.
Step 6 — Stain as normal.
With the residue gone and the surface prepped, your stain or dye should take evenly across the entire body.
