    Default Mould in timber

    I have just rescued a luggage side table pictured below, solid as but there is evindence of water marks and possibly mould.

    will this be removed by stripping, sanding and recoating or will the mould return, if so what can I do to treat the timber before finishing to prevent the return of mould?

    thanks

    Vinegar will (should [emoji849]) kill mould.

    Outdoor furniture oil has anti fungal in it also. You could use vinegar as a wash after stripping back to bare wood then finish with outdoor furniture oil to keep the mould at bay. Mould needs a damp environment to thrive and that attack likely took hold when the old finish began cracking and flaking. A nice new finish should leave the mould no place to live.

    The mould spores are possibly deep in the timber.
    A strong bleach should kill the accessible spores, but the deeply buried ones ??

    I suggest you wear an appropriate mask while sanding and incorporate a mould inhibitor in the finish.

    If it is deep and there is a lot of it then oxalic acid will do the deed. It's a bit more aggressive than vinegar so follow the instructions. It's available from most hardwares stores. It also makes a very good non-metal-dissolving rust remover.

    I'm having a hard time seeing any mould in the pictures. If it were me I don't think I would worry too much, it is hardly fine furniture. Vinegar and maybe bleach if you can really see mushrooms starting to grow would be my amateurish approach.

    Most timber (deck) cleaner solutions sold by Cabots, Feast Watson, Intergrain, etc. are either Oxalic acid or Citric acid water solutions plus some colouring agents and probably something that mildly froths for visual effect.

    Diggers Rust & Stainer cleaner is $32 for 2kg at Buπnings and is crystalised Oxalic acid. 100g will make 1L of water solution for wood cleaning. That's good value!
    Also great for removing rust - especially from chromed metal!

    McKenzie's Citric Acid 75g is about $2.75 from Woo|worths. Dilute the 75g in approx 2L of water.
    I've only used it in rust removal which was approx 8L.
