Rust & tannin stain remover
HydraStain
HydraStain is an oxalic-acid stain remover that lifts rust, tannin bleed and black iron-staining wherever it shows up — greyed timber decking, concrete, pavers and stone — restoring the surface closer to its natural colour before you oil, seal or move on.
For rust and tannin staining on timber decks, concrete, pavers and stone — screw and fixing stains, greyed weathered decking, or rust marks left by furniture and tools.
Oxalic acid reacts with iron and tannin staining and UV-greyed timber fibres, lifting the discolouration back toward the surface's natural tone.
