A washi shade does not wear out from being looked at. It ages from four things: sun, heat, dust pressed into the fibres, and water. Three of those you can control. The fourth you simply keep away.
This is the routine we use on our own lamps in the workshop and at home — what to do once a fortnight, what to do when something goes wrong, and what to never do at all.
Where you put it matters more than how you clean it
Two placements will shorten a shade’s life faster than any amount of neglect elsewhere:
- Within a metre of a radiator, fireplace or oven. Heat dries the paper unevenly. It warps first, then goes brittle at the seam where the shade is glued.
- In direct sun for hours a day. This is what turns a white shade cream, and then yellow. It is not dirt — it is the paper itself changing, and it does not reverse.
- Beside a door or window that gets wet. Washi takes a water mark permanently. A single splash near the base is visible for the life of the lamp.
A north-facing corner, a hallway, the space beside a sofa away from the glass — those are the placements that let a shade run ten years instead of three.
Dusting: the only routine that actually matters
Once every two weeks, with the lamp off and cool:
- Use a soft-bristled brush — a clean paintbrush, a makeup brush, or a feather duster. Work from the top of the shade downward so dust does not fall back onto what you just cleaned.
- Use almost no pressure. You are lifting dust off the surface, not scrubbing it out of the fibres.
- Never use a damp cloth. Water marks washi immediately and the stain does not come out. This is the single most common way a paper shade gets ruined.
Do not use a vacuum brush attachment either. The suction pulls the paper away from the ribs, and once a rib has separated it shows as a line for good.
Smudges and fingerprints
For a light mark — a handprint from moving the lamp, a scuff from a box — try a clean white artist’s eraser or a piece of art-gum first. Work in short strokes, lift the eraser often, and stop as soon as the mark stops coming up. Eraser crumbs brush off with the same soft brush.
Low-tack tape — the kind that peels off a page without tearing it — can lift a stubborn spot. Press it on, lift it straight up, and do not rub it sideways across the grain.
If none of that works, leave it. A faint mark on a handmade paper shade reads as material, not damage. A scrubbed patch reads as damage.
A tear is not the end of the lamp
Small tears are repairable, and the repair is genuinely invisible once the lamp is lit:
- Cut a patch of matching washi slightly larger than the tear, with the grain running the same way as the shade.
- Use a starch-based glue — rice paste or a conservation starch paste. Avoid superglue and craft glue: they dry hard, yellow, and pull the paper.
- Glue the patch on the inside of the shade where you can reach it, press it flat against the tear, and let it dry with the lamp off.
- Let the light hide it. Backlit, a well-matched patch disappears. This is the wabi-sabi part, and it is not a consolation prize — it is how paper lamps have always been maintained.
Five things never to do
- No water, no damp cloth, no cleaning spray.
- No detergent, no bleach, no “gentle” soap. All of them stain washi.
- No vacuum brush attachment and no compressed air.
- No scrubbing. If the mark does not lift with an eraser, it is in the paper.
- No higher-wattage bulb to “brighten it up”. A bulb that runs hot discolours the paper above it — the same failure the placement rules are there to prevent.
Repair or replace? You do not have to replace the lamp
If a shade is past patching — a burn, a large tear along a seam, a water stain across a third of the surface — the lamp underneath is still fine. We make replacement shades and single parts for every shape we sell, built the same way the original was. A damaged shade is a shade problem, not a lamp problem.
Send us a photo of the shade and the model number, and we can tell you which part you need. Browse the collection if you would rather start with a whole new shape.
