Rust & Limescale Guide

Vinegar removes limescale from chrome. On marble it causes permanent damage in seconds. Baking soda lifts burnt residue from steel. On aluminium it leaves black discolouration that never comes out. Most cleaning advice tells you the method and leaves out the surface, which is how a small stain turns into an expensive repair. Rust and Limescale Guide is built the other way round. Every method is written for a specific problem on a specific surface, with a clear warning about what will damage that material. THIRTY PROBLEMS Rust, limescale and hard water, soap scum, burnt pan residue, oven grease, mould and mildew, dirty grout, silver tarnish, copper oxidation, toilet bowl rings, washing machine odour, blocked showerheads, kettle scale, water rings on wood, adhesive residue, hard water spots on glass, soot and smoke film. Plus the everyday spills: cherry and berry juice, red wine, coffee and tea, blood, cooking oil and grease, ink and marker, lipstick and makeup, grass, pet urine, chewing gum and wax, turmeric and curry, sweat yellowing, nail polish. NINETEEN SURFACES Stainless steel, chrome, enamel, cast iron, aluminium, marble and travertine, granite, ceramic tile, grout, glass, plastic and acrylic, wood, silver, copper and brass, carpet and rugs, upholstery, mattresses, cotton and linen, wool and silk. WHAT YOU GET FOR EACH METHOD Exactly what you need, before you start. Numbered steps in the right order. Waiting time with a built in timer and a notification when it is done.
