Evapo-Rust 1 Litre Super Safe Rust Remover Non Toxic Powerful Reusable Formula

PRELIMINARY DEGREASING: first always remove oil & greases by using dedicated detergent. DIP: fully submerse the rusty object; then submerse it. The duration for derusting will depend upon the severity of rust: for flash rust removal it takes about 30 minutes and up to 24/48 hours for extremely heavy rust. Periodically check the object during the derusting process to know the status. It is highly recommended to fully immerse the metal items, because some items not fully immersed for extended periods may experience etching at the water-line. If water-mixed the above time interval will increase: the more you water-mix, the more time it needs to complete the rust removal process. To avoid the rust removal process became too slow, do not further water-mix beyond 1:1 ratio. As 1 Lt. of EVAPO-RUST removes till 60 gr. of pure dry rust, further water-mixing does not increase the total amount of rust removed. For extremely heavy rust, periodically rinse item with water and/or softly brush item with a scrubbing tool (e.g.: a wire brush): this stage is VERY important in getting the best results because residual rust may still be embedded in the metal (pits, crevices) after the initial soaking. AFTER-TREATMENT: after treatment, the part can be water or denatured alcohol rinsed for painting, plating, or other type of corrosion protective coating. It is important to always rinse the metal after a treatment: tiny molecules of iron will still be embedded in the EVAPO-RUST solution, and these molecules must be rinsed off with water or they will activate the re-formation of rust on the metal object. If left unrinsed, the fluid will dry on the treated surface to a hard, short-term corrosion resistant coating with no corrosion removal properties. As a dry film, it inhibits oxidation indoors up to 14 days, depending on local room-humidity & temperature and metal item shape (the more irregular will be the shape (with high energy points), the shorter the protection will last)
