Evapo-Rust C700 Rust Remover, 946 ml

Takes a while for it to work not as good as should be expected

I used it to remove rust on the screws of a19th century concertina. The screws had rusted and swelled, so were becoming too tight in their threads. These screws are quite difficult to obtain, so I was keen to restore them without damage. After a very light rub with Scotchbrite I dropped them into a small amount of Evaporust and left them for two hours, then rinsed them thoroughly. The good metal on the screws had become clean, with a light grey colour. The rust had gone, leaving a black pitted surface where the rust had eaten in. This was a really good result, giving me restored screws without removing any good metal. I soaked the screws in GT85 (or WD40) for a couple of minutes, then let them dry off completely, gave them a final polish with tissue and now they are back in use. The Evaporust that I used was only lightly discoloured, so I was able to top it up a little and use it on the next project. So it is a very effective product, which I will certainly keep on using. I really like that is safely disposable for the home user. I have only given it 4 stars because of the eye-watering cost. I had assumed from the photo that I ordered a large amount, possibly 2.5 litres or 5 litres, but I didn't check (stupid I know), but in fact it was only1 litre. This is really expensive stuff! I understand some of the reason why- it has shipped from the USA. So be aware before ordering. Having said that, I will buy more as I need it.

Did the job of cleaning my petrol tank. Easy to use and you can reuse it.

Bought this to clean out a well rusted motorcycle tank - having never used it before I wasn't sure how strong or fast acting it is, so I dipped my toes in with a 1L bottle. It's nowhere near enough to do the job, and the amount required would be prohibitively expensive. After 24h it had made a small difference, and I could see that with a smaller job like taking rust off some tools in a small container it's probably good. For a fiver less than the 1L of evaporust I got 20L of white vinegar delivered from a well known online auction site, which filled the tank completely and thus cleaned all sides perfectly without me having to turn it over and slosh it about all the time.

Brilliant, got tank cleaned and rust free

This is a great product very powerful and yet is biodegradable. I have been very pleased with the results and would buy again

I recently purchased the Evapo-Rust C700 Rust Remover, 946 ml, with high hopes based on its claims of being a powerful and effective rust cleaner. Unfortunately, my experience with this product was disappointing.Despite following the instructions precisely and allowing ample time for the solution to work, the results were underwhelming. The rust on my tools and metal objects was only partially removed, and in some cases, there was no noticeable improvement at all. I had to reapply the product multiple times, but the results remained inconsistent and unsatisfactory.Additionally, the amount of product required to achieve even minimal results meant that the 946 ml bottle was quickly depleted, making it an expensive and inefficient solution for larger projects.Overall, the Evapo-Rust C700 Rust Remover did not live up to its promises. Its inconsistent effectiveness and high usage rate make it a poor value for the money. I would not recommend this product to anyone seeking a reliable rust removal solution.

I'll update with pic later.
