Hi
any suggestions on to clean the inside of the fuel tank before I store it. I'm not intending to get it resprayed for another year or so. I'm still stripping my Honda.
thanks in advance

Have you considered using electrolyte and a sacrificial anode? Can’t remember the precise details as its a few years since i employed the tecchnique on my RD tank.... but basically fill the tank with electrolyte (soda crystals and water solution) suspend a metal coat hanger in the tank through the middle of a plastic bung fashioned from an old oil can lid or similar, to isolate it from the tank. Then connect a battery charger to the tank and the coat hanger (can’t remember which way round) and leave for 24 hours.... you’ll be amazed at the amount of rust that lifts off the inside of the tank and deposits on the coat hanger... Works a treat!

Ps, you need to remove the petcock and seal the hole iirc..... i think the aluminium alloy will disappear if you leave it on......

thanks Rob62.
I'll YouTube and Google the recipe and have ago

I have treated a few tanks like yours (i.e. lightly rusted)with Deox-C. Then you just need to coat with light oil, WD40 or other rest preventive. I think Bilt Hamber may even do a secondary rust preventative product but never used it.

Deox-C ordered. Is it crime once I've used this to pour some engine oil and swill it around for storage. I can wash it out later with petrol

Probably not ...I think Honda applied some type of protective oil to spare part tanks. I think the key is to prevent flash rusting after de-rusting but there is not the same flash rusting with DeOx-C that you get with mineral acids such as hydrochloric (brick cleaner). Phosphoric acid isn't bad as it phosphates the metal and I think is provided with some tank liner kits but you won't go far wrong with Deox-C.

I fill my tanks with diesel for storage. Once out of storage, drain diesel, rinse out with petrol and it is ready to go ;)
-
Can I have the diesel when you drain it :D I know .99p a litre ;) ;)
-
the 'after' shot. I let it soak 2 days ;D
that deox-c worked really well. I'm trying an experiment with the remainder, got a bucket of it mixed, dunked in a couple of rusty parts.
-
Glad it worked OK .. it works OK until it goes black. I don't use it for gears etc though.
-
The stuff I emptied of the tank isn't black yet, hence why I'm using it again, as an experiment. I have the air filter holder in which probably needs replacing but I'm interested to see the difference.
