Osmo Tannin Spot Remover 6602 – 250 ml

Osmo Tannin Spot Remover 6602 is a ready-to-use cleaner for dark tannin reaction marks on untreated or oiled wood, especially oak. The 250 ml spray bottle lets you treat a marked area on a table, worktop, floor or piece of furniture before restoring its oil finish.

Dark rings can form when moisture or metal reacts with the tannins naturally present in wood. This cleaner targets those marks locally. It contains oxalic acid and is supplied ready to spray, with no dilution required.

How to use Remove loose dirt and test on a hidden area first. Spray evenly over the stain. Allow it to work until the mark improves, for no longer than 30–45 minutes, then wipe with a lint-free cloth. Repeat if necessary and wipe clean with water. Let the wood dry thoroughly for approximately 24–48 hours before applying a suitable Osmo Maintenance Oil or Polyx-Oil to restore protection.
