{"product_id":"sonitron-browning-remover-concentrate-20l","title":"Sonitron Browning Remover Concentrate 20L","description":"\u003cp\u003eSonitron Browning Remover Concentrate is an oxidising type of browning remover. Its active oxygen source completely evaporates, leaving no active residues, and Sonitron positions it as the first choice for cellulosic browning and tannin stains. The active ingredient is hydrogen peroxide at 30–60% (SDS), so it is a strong chemical that must be diluted and handled with care — see Safety below.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOxidising remover\u003c\/li\u003e\n\u003cli\u003eNo residue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis is the 20 L pack for restoration and high-volume work.

Water dissolves natural colouring (tannins and lignin) from cellulose materials such as jute backing and cotton, and as the carpet dries it wicks to the fibre tips and concentrates there — most heavily at the edge of a water mark. Tea, coffee and similar organic stains leave the same kind of tannin colour.\u003c\/p\u003e\n\u003cp\u003eSonitron describes the product as a way to remove cellulosic browning rapidly and economically, even on large areas, using the extraction machine.\u003c\/p\u003e\n\u003ch2\u003eDirections\u003c\/h2\u003e\n\u003ch3\u003eDilution\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFor heavy cellulosic browning, mix 1 part Browning Remover Concentrate with 10 parts water.

Apply Browning Remover Concentrate directly to the stain. Tamp with a spotting brush to allow the product to fully engage the stain. Allow several minutes of dwell time before blotting away with an absorbent cloth. Rapidly dry the treated area to a finish using a hair dryer. Repeat the procedure as long as the stain is responding.\u003c\/p\u003e\n\u003ch3\u003eImportant: Spotting Dilution\u003c\/h3\u003e\n\u003cp\u003eThe spotting directions above say to apply the concentrate directly, while the note at the top of this page says it must be diluted. Sonitron's own Browning System instruction sheet uses the Remover at 1 in 10 in hot water for tea, coffee and urine stains, after a first treatment with its Browning Preventive. Because the concentrate is 30–60% hydrogen peroxide, CCW recommends spotting at 1 in 10 and pre-testing until Sonitron confirms whether neat application is intended.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo not mix Sonitron Browning Remover Concentrate with any other product.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eFor larger areas and water damage restoration\u003c\/h3\u003e\n\u003cp\u003eApply Browning Remover Concentrate at its pre-tested safe maximum.

At 1:10 a 20 L drum makes 220 L of working solution, and at 1:40 it makes 820 L. Hydrogen peroxide loses strength over time once a container is in use, so buy the size you will use while it is fresh and keep it sealed, cool and out of sunlight.\u003c\/p\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2179\/6391\/files\/Browning_Remover_Concentrate_-_SDS5004.pdf\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eSafety Data Sheet (Sonitron, SDS 5004, revision 3, 30 January 2026)\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003ca href=\"https:\/\/ccwonline.com.au\/collections\/dangerous-goods-shipping-surcharges-apply\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2179\/6391\/files\/CCW_Dangerous_Goods_Limited_Quantity_Mark_png.jpg\" alt=\"Dangerous goods limited quantity mark\" width=\"31\" height=\"29\"\u003eDG Shipping Surcharge Applies\u003c\/a\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eRelated Products\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/sonitron-browning-remover-concentr-5ltr\"\u003eSonitron Browning Remover Concentrate 5L\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/actichem-brownaway-5-ltr\"\u003eActichem Brownaway 5 L\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/browning-treatments\"\u003eBrowning Treatments\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/structural-drying\"\u003eStructural Drying\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/safety-ppe\"\u003eSafety \u0026amp; PPE\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003eNot sure which browning treatment suits the carpet?
