Rusty Tanks
« on: June 10, 2015, 07:13:27 PM »
Hello Everyone
                      Could someone tell me the best way to neutralise the effects of molasses after using it to de-rust the inside of petrol tank, the molasses does a good job of removing the rust, but have tried a few things and the rust does come back cheers.

wash out molasses with hot water, tip out the water then straight away spray the complete inside surface with WD40, then tip out the WD40, blow any droplets of water out with compressed air and then let it dry out somewhere warm and dry. When in use after that, keep it full of petrol (to avoid condensation forming on the inside). If you don't ride it much, change the fuel for fresh fuel every few months.
If it is a museum bike, just do the WD40 treatment and dry it out, or do the WD40 treatment and then keep it full of oil.

flush it well with warm water to get all the molasses out and then  rinse with metho to get the water out.
after that just add two stroke fuel with heaps of oil in it and swish it around.
