I bought a butcher block maple dining table from a high-falootin' place in
Chi-town (by my standards, anyhoo) and after about a year, small greyish
areas (about 1/4" by 1" striations) started to appear below the finish (no
idea what finish, but it appeared to be sealed up pretty good) and not
necessarily following any grain pattern. Since it was indeed below the
finish, they replaced the table (delivery and everything - ain't that nice),
even though we hadn't been very "nice" to the table (when you need a
workbench in a condo, anything will do).
The replacement table had the same thing happen. By that time, the table
had been discontinued, so they gave us a beefier maple table and it's been
fine for the last 6-7 years (although it has been used as a workbench).
Any idea what would cause maple to develop spontaneous blemishes, not
following a grain pattern or any joints?
What wood? What finish? What was cause of "stops", meaning "strips",
TLI (too little information).
Don't use bleach until you know WTF is going on! Bleach is good,
bleach is great. Bleach can foul up wood to a degree that you can't
imagine. It can literally dissolve the fiber (i.e. destroy the wood).
More data required.
See, that's an important detail.
You left the furniture outdoors. Bleach will not solve the problem. Sand an
refinish. The really good news is that you get to do this roughly every
other year for exterior "furniture".
Even the best exterior clearcoat products are good for about 2 years before
recoating is necessary.
Your other options are paint or lear to like a natural silvery gray.
