For rust removal, consider using a phosphoric acid-based rust converter or vinegar. After applying, let it sit according to the product guidelines, then scrub with a wire brush. Rinse well to ensure all rust is gone!

I’ve had great success using electrolysis for rust removal. It’s a slower process but can be very effective without damaging the tank metal. Just make sure to follow safety guidelines closely!

Electrolysis sounds interesting! Could you share more about how it works and what materials are needed?

Sure! You need a battery charger, water, washing soda, and an iron anode. The charger powers the process, and it effectively lifts rust from the tank interior by converting it into a soluble form.

After cleaning, how do you ensure the tank is properly sealed? I’ve heard about using sealants but want to know the best approach.

To seal the tank, allow it to dry completely, then apply a tank sealer designed for metal. Follow the manufacturer’s instructions closely for the best results!

Are there any specific brands you recommend for tank sealers? I’ve seen so many options!

I’ve had good results with Red-Kote and POR-15. Both are durable and designed specifically for fuel tanks, so they should do the job well!

Thanks! I hope this won’t be as messy as I think. Any tips on minimizing spills while applying sealant?

Using a funnel and applying in a well-lit area can help prevent spills. Also, masking tape around the rim can help catch drips! Just take it slow.

Honestly, I’ve tried this and ended up with more mess than I anticipated! Just have plenty of rags on hand, just in case.

Haha, that’s a good point! If only cleaning fuel tanks was as fun as cleaning our kitchens!

Cleaning a plastic fuel tank can be tricky! I recommend using soap and warm water as a safe cleaning agent. Always avoid harsh chemicals that might damage the tank.

Great advice, Adam! I would also suggest rinsing thoroughly after cleaning to ensure no residues remain.

It’s vital to prevent any chemical damage. Always check the compatibility of cleaning agents with the material of the tank before use.

I wonder if anyone has dealt with stubborn residues? I’ve heard using a mixture of vinegar and baking soda can help, but does it really work?

Yes, it does work! I’ve used it in my tank, and it removed a lot of residues without damaging the plastic.

I totally agree with avoiding strong solvents. They might seem effective but can really compromise the tank’s integrity.

Very true! I’ve also found that using a soft-bristle brush can help clean without scratching the tank.
