Shield Technology Restore Rust Remover is a highly concentrated, fully biodegradable, liquid rust remover that you mix 19:1 with plain water, so this 250ml bottle will make just under 5 litres of finished strength product that can be re-used several times over.
Submerge your rusty item in the solution, and after a couple of hours the rust will have been dissolved. In extreme cases it may be necessary to rinse the part clean and return it to the solution for a second dip.
Unlike phosphoric acid or other acid based products, Shield Technology Restore Rust Remover is approximately pH neutral, will not attack good metal, plastics or non ferrous metals. It is best to remove any wooden handles though as the water will damage them.
Once the de-rusting process is complete, restore leaves the surface passivated - so there is no problem with post-treatment 'flash rusting' associated with acidic formulations. The other advantage is that when you are finished with it, you can simply pour it down the drain without damaging the environment.
For long term protection against further corrosion, we recommend Shield Technology MetalGuard Ultra, VanGuard or ToolGuard products.
Formulated, developed and produced in England.
