Has any one any ideas on an easy way to clean rust from the inside of a petrol tank.Alan's dr750's been layed up a while
and the inside of both tanks are covered in surface rust. We have thought about electrolysis but don't know how viable it
is on this sort of area or even if we want to fill a tank with washing soda !

Ok guys over to you

If you know anyone with a cement mixer, saves a lot of effort if you gaffer tape it to the outside  Grin

Finally got around to trying to clean out my fuel tanks of the Dr 750 Big,
This is what she looks like

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/31032012854.jpg
rusty tanks


With lack of use during the last few winters and sweating of the tank this is the condition inside

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/180320131134_zpse08da790.jpg
rusty tanks


and the other one, yes two tanks fitted on this beast

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/230320131166_zps1532205a.jpg
rusty tanks


So I thought I'd try electrolysis as I reckoned molasses = sugar and would be near impossible to wash out of the tank as it is impossible to completely drain

The ingredients

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/180320131132_zpscdb60c08.jpg
rusty tanks


Mixed up 2 desert spoonfuls of soda crystals to 4 litres of water, and it took 4 1/2 gallons to fill this one tank

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/180320131133_zps7b9208ee.jpg
rusty tanks


Used a bit of 8mm threaded for the anode rod as it was available with a piece of rubber on the end to stop it shorting out

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/180320131135_zps63021c72.jpg

A few holes to allow the hydrogen gas to escape

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/180320131136_zps2e24fae0.jpg
rusty tanks


Wired up the battery charger, positive to the anode and negative to the tank

The battery charger was supplying about 2 amps to the process

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/180320131140_zps83af566e.jpg

So let this do it's thing and the next day the 8mm rod looked like this

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/190320131161_zps9f29230e.jpg
rusty tanks


Cleaned it and put it back in

After 3 days the rod looked like this, seems to be collecting something

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/190320131161_zps9f29230e.jpg
rusty tanks


Cleaned the rod again and put it back in

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/210320131163_zpse086888e.jpg
rusty tanks


After 5 days the rod had collected rust to look like this

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/230320131164_zps0bda4ad1.jpg
rusty tanks


After a week I emptied the solution out and filtered it into the second tank, to start on it
After washing the crude and remainder of the loose rust and gunge this is how it looked

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/230320131167_zps5a50d0cb.jpg
rusty tanks


Not perfect but clean enough to not give any bother, so it needed to be dried pretty quick before it began to rust again

http://i509.photobucket.com/albums/s336/dr-big750/Bikes/230320131169_zps837c4194.jpg
rusty tanks


Finally found a dual use for her indoors hair dryer, When fully dry I'll wash out with diesel and then with diesel and some engine oil mixed and leave this in it until ready to fit to the bike
