99.6 % PURITY | 1 kg PACK |
Oxalic acid dihydrate at 99.6 % in a 1 kg pack: a technical cleaning reagent for the apiary and the workshop, not a medicine.
It is used for what it genuinely does outside the hive: taking propolis off equipment, rust off tools and grey off timber. And it is worth reading the notice below first, because almost everyone arrives looking for something else.
⚠ LEGAL NOTICE
Oxalic acid is the active substance of the registered varroa treatments, which is why many people arrive here searching for «oxalic acid for varroa». The veterinary medicines authorised by the AEMPS — such as Api-Bioxal or Varroxal — carry the acid already formulated, dosed and with an approved route of application. In Spain, varroosis is treated with a veterinary medicinal product, under the supervision of the holding's veterinarian (Royal Decree 608/2006). This product is not a veterinary medicinal product. Treating it any other way is an infringement under Animal Health Law 8/2003. If varroa is your aim, your legal option is in the Hive Health section, not in this pack.
01 · EQUIPMENT AND CLOTHING
It dissolves propolis stains, residues and ground-in dirt on suits, gloves, veils and tools. It leaves the kit ready for the next inspection without resorting to harsher solvents or ruining technical fabrics — which is what usually happens when people reach for an industrial stain remover.
02 · RUST AND TIMBER
It dissolves and removes rust from tools and metal parts and lightens stained or greyed timber on hives, frames and furniture before repainting or varnishing. It is one of the uses buyers rate most. Rinse with water after applying, to fix the result and leave no acid residue on the surface.
03 · HONEY HOUSE AND WORKSHOP
It polishes marble and granite, tackles limescale and rust marks on sanitary ware and tiles, and degreases machinery. In wax recycling a rough guide of 150 g per 100 kg is used to carry impurities out and leave the wax looking cleaner before milling — always as work on the material, in the workshop and outside the hive.
⚠ PRECAUTIONS
Danger. Harmful if swallowed or in contact with skin, and causes serious eye damage: the risk is the dust, in the eyes, on the skin and in the mouth. Work with chemical-protection gloves, tight-fitting goggles and an FFP2 mask, without raising dust and in a ventilated area. If it gets into the eyes, rinse with water for several minutes and call a poison centre or a doctor. Keep out of reach of children and away from food. This shop accepts no responsibility for improper use of the product.
04 · BEFORE YOU BUY
This is a bulk chemical, with no dispenser and no beekeeping application instructions, because it has none. If what you want is to treat varroa, what you need is a registered medicine.
