Simple Green! Its cheap and is perfect for cleaning tanks. I pull the tank and clean with 100% Simple Green, (let it sit for 5 minutes and shake it around), rinse with hot water, hit it with an air compressor to dry. I do this every 3-4 gallons or so, never had an issue, and I'm kind of a motor guy saying this. It works!

OMG WATER?

lol


I have had 100% success with dawn dish soap and water. I have let tanks air dry, and I have used compressed air to dry them.

Yep, once the water dries out, its gone. Water will not hurt the plastic tank or fuel line, its not like you leave it in the tank. lol. Simple green does a great job dissolving oils and residue, but wont hurt the plastic or o-rings. I do sometimes use a small amount of compressed air to clean out the clunk when installing new fuel line. Just send the air down from the fuel line to blow out the grime reverse of its normal flow, the clunk can hold dirt easily. The main thing is let the tank dry well.

You guys work too hard. Rinse with solvent and dump it out. Done. No compressed air needed or any dry time to worry about..

you guys need to try Miracle clean... works just as good as brake clean but without the harshness... mixed with simple green it literly debonds dirt off plastic and turns grease etc into a liquid and falls off

Or if money is no object, order a new fuel tank. Whatever makes you happy I guess.

Hard way, dawn dishsoap and keeping your lid open to dry damaging your return springs strength and possibly not cleaning everything out enough, less harder spray it with something like contact brake cleaner, less harder use nitro gas/denatured alcohol or acetone and flush it a few times with a final nitro fuel rinse if using d.a. Or acetone! Easy way new tank. My way.. clip the fuel stone out and clean in a bowl of contact cleaner and replace all fuel lines. Those are your options. I wouldn’t feel confident AT ALL if I didn’t pull the fuel stone out (clunker?) but I will admit I may do this before replacing my tank but I have a good 15 tanks in bags ready to go. I love throwing new tanks in. I have a bad habit of replacing them before noticing the stones been pulled back which causes major tuning issues.

Normal use of the your fuel lid return spring to open and close the lid while re-fueling multiple times per day will weaken the spring more than leaving the spring/lid propped open over night. Most likely nobody will ever wear out a fuel door spring on these toy cars, you would need to repeatedly use the same tank for numerous years to do so. I personally have a HPI Nitro RS4 3 evo ss with the original fuel tank with the primer in it from 2006. I have used dawn dish soap and water with a paper towel blocking the door to keep it propped open while it dries for multiple days. That fuel door return spring works perfectly fine to this day.

Or, use compressed air (in a can, or from a compressor and dry it out in seconds) as mentioned multiple times before.

Either way it seems we have all repeated ourselves in this thread with the same methods that all seem to work fine.

Good idea about the fuel filter/stone/clunker.
