Essential Rust Remover is efficient at removing rust stains. These can be caused by iron-containing products, metal garden furniture, leaking heating systems, and so on. The gel-based formula is straightforward to apply, safe, and pH neutral, making it suitable for use both inside and outside. It will begin working immediately, attacking the rust stains while the chemical formula produces a purple-coloured reaction, allowing you to see the remover at work. Coverage will vary depending on surface contamination, but should cover up to 10m2 per litre on average. Available in 1L and 5L HOW TO APPLY :  1.
