Has anyone used the 'reverse electrolysis' method of tank cleaning as described in the link below?

I've used an electrolysis kit from Gateros several times. Works well.

cheers for now,

Simon.

Hi, I have used that method that is shown in Real Classic and it works very well indeed, it is amazing how much rust attaches to the electrode in the tank I found I had to take it out and clean it off about every 2 hours.Regards Basil.hope-that-helps

This looks just what I was looking for on cleaning rusty tanks. Can anyone tell me what the pictures are trying to say?

 

Many Thanks

Hi PJH  ...  Buy litre bottles of the cheapest vinegar i.e supermarket own brand ... making sure you have put either the tap back in or used an appropriate bung (Screw in type)... it took just over 6bottles fill the tank but leaving enough space to shake the tank and allow for displacement ... I then added some old ceramic baking beans, but small stones/gravel will do the same ... I gave the tank a good shake and then left it for several days (Shaking daily)

Get a fine sieve or muslin place it over a bucket/container and tip vinegar out ... you can then wash off the beans or stones/gravel and re-use ... the vinegar can be re-used if you want ... just don't put it on your chips

Now rinse the tank and dry it ... I used my hot air gun on medium heat ... make sure it is totally dry ... I then put cling film around the filler hole to keep the damp out ... seems to have worked very well so far.

 

As to the 'Spirit of Salts' I have used it to blitz the loo when I moved in my house but you have to be very careful ... if you dilute it add the SALTS to the WATER as the other way round and it will boil ... this is Hydrochloric acid  be very very careful wear gloves and goggles

Hello Graham,

I did vinegar several times with and without screws and pebbles and had the same problem, still had loads of crap coming from somewhere and not really shifting the rust.

It would seem clear but every time I fuelled it up and tried to run it the carb just blocked up with silt again even with the inline filter on and bike wouldn't run.

Then tried cheap Aldi cola at 42p for 2 litre bottle, I'm sure other brands are available and possibly cheaper.

Fetched loads more crap out and seemed to get rid of much more rust.

Swilled it out with bicarb soda and water then blasted it out with the hosepipe and dried it as best I could with the blow lamp.

Flushed it out a few times with small quantities of neat petrol until it was coming out reasonably clear.

Put some fresh petroil mixture in and it started up and ran ok.

Took it out for a short run but need to set the carb up now and stop the throttle sticking wide open - cable no good or snagging or slide sticking - or both.

Give it a try - you can only lose £1.68 and a bit of time.

If you've been at it as long as I was you can probably go through the whole process in your sleep now.

Good luck.

Got a bit further we are at nearly 2 weeks I have empty the tank again (some more rust gone and now have some grey metal) and put the screws back in along with more rusty nuts and bolts (the screws are like new now with no rust) gave a real good shake, then re-added the vinegar (strained) and gave another good shake. Will shake it every day for the next week and then see whats there.

Hi all,

inside of my D5 is only a bit rusty but just to be on the safe side, i have it full of vinegar right now. Noticed that the strongest white vinegar in the supermarket was Sarsons pickling vinegar at 6 per cent acidity, with the others only 4. So bought three big jars, which was all i could carry! Found that the cork from a Sailor Jerry's rum fits very tightly in the tap hole, and no leaks so far. Added garden gravel. Can see a little bit of fizzing going on. Will check on it every day. After just a few hours i thought i could see a difference between the metal above and below the vinegar level! Apparently after finishing the vinegar process you should use a neutralising solution of baking soda to get rid of all the acid, and rinse it out really well with water before drying quickly. Loads of videos on utube.

I filled my tank with vinegar & a handful of M6 bolts that I shook round every now & again, I left the whole thing to sit overnight & drained it all in the morning. I had a lot of very fine rust & some larger flakes but there's still an awful lot in there.

Just to add my experience in this...

Having old plastic sealer inside the tank, that was broken in the form of big flakes, Acetone did amazing job, softening the material and allowing it to come out easily. Just soaked it one night in Acetone..

Electrolysis.

This is what I did to my Matchless tank. Worked really well.

I bit the bullet today and tacked the rust on the inside of my fuel tank.

Yes, I should've sorted it before I had it painted but I'm still learning!

A few months ago I half filled the tank with vinegar & a handful of M6 nuts to clear out a lot of the lose stuff.

Today I poured in 8 or so handfuls of very small fish tank gravel to remove any more lose rust, it did a great job! As I poured the gravel out I got a huge amount of rusty dust too.

Then I filled the tank with a bottle of Spirit of Salt (this is nasty stuff, be careful), rolled it around for 20 minutes, poured that out and half filled the tank with 3 pints of cold water & 5 capfuls of bleach to neutralise the acid.

I then used the Frost POR15 motorcycle repair tank kit that I bought, which includes a degreaser, a metal prep & the sealant.

After I've had a solid 6 hours of nasty chemicals & manual labour due to constantly having to rotate the tank I was done!

The sealant is setting now & I couldn't be happier with the result, it's totally transformed the inside of my tank.

After i removed my fuel tap yesterday, to check, i am in the happy postition to add one more tip in the section! laugh

The previous time i removed the tap (15 days ago), it was blocked by rust flakes, and the float was limited (due to the lack of tap filter).

I decided to throw a big round magnet ball (1'' diameter) inside the tank, and push it near the tap side...

Well, it looks like the trick had worked ok, because i didnt see a sinle rust flake in my tap!! thumbs-up
I didn't make any efforts to retreive the magnet yet, but i am sure that is doing what is supposed...collecting loose rust pieces. I suppose, that it also magnetizes the rest of the tank, attracting all small bits to stick in the metal, instead of flowing into the tap with the fuel by gravity...

I also noticed the inline filter is also more clear now, after i replaced it becasue there were too many rust particles inside...

And the usage of the engine, was more the last days, since i am experimenting with the carburator, to see if i can achieve any close to normal performance..

P.S. I decided to proceed in this, because even after the cleaning process, i still have rust remaining in the tank.
I will fit also a tap with tank filter, for better results. Aplying a sealer (like por-15) it's not an option after the paintwork has done on the tank..dunno

There is another article from the same Real Classic magazine which uses 3 chemicals.

** Please log in to view **

I have just used it and the tank looks like bare metal on the inside.

A big advantage of this method is that no nuts bolts stones etc are rattled round inside the tank damaging the fine filter on the tap.

Hi All

Here’s my feedback on using the 3 chemical tank cleaning method from the ** Please log in to view ** article, which did successfully remove the rust from my tank once I made some changes

My 1966 D7 tank had never been lined or sealed but was very rusty inside and also had old oil in it which had been added a long time ago to act as a preservative in storage.  To describe what ‘very rusty’ means, in the early 80’s there was enough rust going down the petrol pipe to block the carb fuel filter and stop the engine, and nothing was done about this increasing rust until August 2017!

I used a bolt, washer and o ring to seal the petrol tap hole during the process.  My petrol cap cork seal did leak a little whenever inverting the tank, and the Spirits of Salt did remove some of its chrome in doing so, which  isn’t an issue as its going to be re-chromed, but be warned if your cap is in good condition. The original balance tube between both sides of the tank worked fine

I did wear the recommended safety equipment when carrying out the below.

  1. Caustic Soda – as bought from diy/hardware stores.

Following the article instructions, caustic soda was left in the tank for four days and when the solution was emptied its colour and contents were not as bad as described.  I estimate that just two days soaking may achieve the same results for a similar un-sealed tank. (The used solution still did a great job of cleaning and stripping old oil and solidified grease from frame parts)

  1. Spirits of Salt (hydrochloric acid) – as bought from diy/hardware stores.

This acid is as strong and evil as described! – e.g. when adding this to the water already in the tank the neat acid dissolved all the rust on the its way to the base of the tank, leaving shiny metal showing the path it took.  I initially followed the exact method in the article but for my tank I only got satisfactory rust removal after I doubled the volume to 1100ml of water and 1000ml of Spirits of Salt – which then covered more tank area, and left this in the tank for much longer - 20 hours in total.  I also left the tank on each side and each end for an hour, and gave the inside area of each badge an hour too. The tank was inverted and shaken when changing positions and was left level overnight so that the 2 bases of each tank side had the longest dose of acid as these were the most rusted areas.  

Once the acid was drained a strong jet of water was directed around the tank which did help clear the rust flakes out.  I dried it by alternatively standing the tank on either end and using a hair dryer.

  1. Phosphoric Acid 40% (Scale-X brand) - eBay

This was used neat to prevent flash and long term rusting. 500ml was swilled around the tank and left for about 30 minutes. The added benefit was that any unseen remaining rust would also have been treated by this phosphoric acid. I did not rinse the tank with water afterwards, just let it dry

Outcome

All the (visible) rust was removed from the tank. No pinholes were found, but the process did highlight that one of the balance pipe connectors had corroded and needs to be replaced.  I am leaving the tank without any sealer and hope that none will be needed. – I will update if this changes.

Cheers
