There seems to be quite a bit of crud in the tank. While it was open for a few weeks, I wondered if the access to light allowed the growth of fungus inside the tank.
DO NOT use acetone, yes it will melt the tank.The tank is plastic, will acetone harm it?
Don't pour it on the ground, it'll contaminate the water table. Burn it, recycle it or give it to someone with a waste oil heater. We have herbicides for weeds. Yes, they are petro based but designed to degrade.I've got some gravel that needs weed killing so that's we're I think old fuel will go.
I wasn't sure, why I said to take a little on a rag and test the tank surface first. I have steel fuel tanks.DO NOT use acetone, yes it will melt the tank.
Use a little alcohol to rinse the remaining water out of the tank.
You might want to rethink your reply to me!You might want to power wash it inside with Purple Zep or Purple power and then rinse it with acetone, not alcohol.
Post 20, I knew I posted it. Sometimes I think I did but didn't. This time however, I did.Don't know. Take a small amount on a rag and rub it on the outside and see if it reacts with the tank material.
Yep LATER, after he questioned you, you said to test it.Post 20, I knew I posted it. Sometimes I think I did but didn't. This time however, I did.
I hope for you it is too!Thanks again and hopefully this problem is solved.
