2 Litre Rostio Tank Rust Remover + 500 ml Tank Protection Emulsion Tank Sealing set – Tank Rust Removal Made Easy

Did exactly what was required. Perfect solution to a rusty tank.

Product works effectively, used 2 bottles for a 16l tank and sealer afterwards is key as surface rust returns quickly without it, don't ask me how I know

So i bought this to de rust a fuel tank and oil tank on a 1950 BSA motorcycle.I'm guessing its a phosphoric acid mix but i couldn't find a data sheet for it.It does work on medium corrosion.... But you DO NEED TO COMPLETELY FILL the vessel for it to work.... No air pockest....If you only half fill and slosh it around every few hours the corrosion will just take hold on the part of the tank that isn't submerged... Worse than when you started.If your tank is 18 litres you need the 2 full bottles.Hot water also rapidly increases the effectiveness.Remember though if your tank is really bad you will just end up with pin hole leaks as the acid eats away at the paper thin rust that was holding the petrol in..... Also you could just buy the acid and make the mix yourself.Good luck

I haven’t ridden my SV650S for 9 years since the kids came along. When I opened the tank I was gutted to see the caked rust flakes. I did a bit of research and found Rostio. To be honest I wasn’t expecting to much but I couldn’t believe the results. The dilution was 10:1 per litre of hot water. My tank is approx 15 litres so I just used the two bottles to give it a bit more strength. I also bought a cheap immersion heating element from eBay and let it bubble for about 8 hours. I then wrapped it in old blankets to keep the heat in and left it for approximately 40 hours. I emptied the tank and flushed it out with cold water several times until all the rust flakes and crude were gone. There was a lot of rust pieces and I needed to swirl the tank and fast flush it to remove any flakes left behind. I then swirled the tank out with the Rostio emulsion to help protect the tank from further rusting. The results are amazing! Its a little more expensive than using litres of white vinegar but IMO Rostio is quicker and it leaves a professional job. I would definitely recommend this product. Just follow the instruction and you will also be pleased with the results.

Excellent product and great results, I tried the vinegar method and it didn’t work but I was great full this cleaned a very rusty tank. Worth the money and easy to use. 48hrs all in to clean rains and add last tank protector fluid.

Worked a treat. Tank looks like new. I used 2 litres. So 20 litres when diluted as i wanted tank full to the top.

I was derusting a Kawasaki Z750 tank that had been left outside for nearly 4 years, when I got the tank off and drained the fuel it was awful. There were large chunks of rust and water in the fuel, most of the inside was peppered with rust and I genuinely thought that the tank was past redemption(nearly £1000 to replace from Kawasaki!). I removed the tank cap, fuel sender unit and the fuel pump and purchased some large corks to seal the holes. I made up the solution as recommended and left it in the tank. As I couldn't keep the solution hot I just left it for over a week, turning the tank and swilling the solution around on a daily basis. RESULT, the tank is almost completely free of rust, I emptied the solution and swilled out the tank a few times and then then used the supplied sealant to make sure no further rusting occurred. I have an NC29 Honda CBR400RR to work on next and I'm hoping for the same excellent results.

The tank rust remover worked brilliant removed alot of rust from my tank and showed a few tiny holes after so had to repair but be careful not to put on paint work has luck i had to do some repair to tank and respray as of tank sealer that didn't do any to seal it but other products were brilliant
