How to Clean Sawdust From Wood Before Varnish

Kathryn Hatter

The process of preparing wood for varnish may involve numerous steps, including sanding the surfaces to make them exceedingly smooth. Because the wood surface must be free of all sawdust particles to achieve a flawless finish, the final task is cleaning sawdust from wood prior to applying varnish. Use a keen eye for dust and take your time to ensure that you remove as much sawdust as possible.

Preparing wood for varnish requires careful attention to detail.

Step 1

Moisten the terrycloth towel and wring it out so it remains merely damp. Wipe every surface of the wood with the damp towel to remove the sawdust. Change towels to use a clean towel when you notice sawdust covering the towel.

Step 2

Use the toothbrush to loosen sawdust from nooks and crannies. As you loosen the sawdust, vacuum the loosened sawdust with the nozzle or brush attachment to clean it from the wood thoroughly.

Step 3

Wipe the wood again with a moist terrycloth towel. After wiping the wood thoroughly, examine the towel to see how much dust you removed. If you notice the white towel showing signs of sawdust, change towels and continue wiping until you no longer notice sawdust covering the fabric.

Step 4

Allow the wood to dry completely.

Step 5

Wipe the surface of the wood lightly but thoroughly with the tack cloth. The surface of the tack cloth has a special formulation that will remove microscopic sawdust from the wood as a final preparation before applying the varnish.
