Have just removed fuel tank from CL350, the motorcycle sat idle for 14 years inside a garage.
Fuel was not drained from tank prior to being parked. Major rust, odor and ooze inside tank.
Would appreciate any recommendations for cleaning the tank. Is is really necessary to install a liner inside the tank, i.e. Kreem, POR 15 or others, if the tank does not leak? Would cleaning properly and then coating the inside of the tank with WD-40 or other chemical be sufficient for coating the tank before filling with fresh gasoline?

Thanks,
Bryan Menard

Welcome aboard, if no one else has said it yet.

I'm partial to vinegar and time. Worked like a champ on my CB200 tank, eventually, after some self-imposed tribulations. Search around for my post on it.

**edit** here it is:

Evaporust from the hardware store. Easy, safe, cheap. Buy a gallon and put it in the tank. every couple of hours, rotate the tank to another position. May take a few days.

Electrolysis is another method. Do a search.

I'd never coat a tank with Kreem. I've seen the stuff peel off.

I've never coated mine, just kept them full of gasoline.

I bought the POR-15 kit and worked on my tank last night.

How I tried to protect the outside of the tank. This was ripped off shortly after the first step of the restoration process because I didn't seal the openings well enough and the cleaner spilled out and made a mess.

After step 1, I decided to just be careful and immediately wash off anything that got on the tank.
Step 2

Step 3 is the sealer. This stuff is messy and is a pain to get off of items that don't need to be sealed....ie hands, clothes, outside of tank...etc. Here you can see the sealer as it coats the inside surfaces.

Be careful and don't spill this stuff on yourself or anything you care about.
I had my work clothes on so I didn't care if I got it all over myself, my hands however, are going to have this stuff on them for a few days I think. I was wearing gloves initially but took them off after step one...BIG MISTAKE.

I will let you guys know how the tank looks over the next few days. I'm supposed to wait 96 hours before I put fuel in the tank.
