Just pondering the idea of using vinnager to clean out my rust cb350 gas tank. I want to use something cheap and harmless to the paint. Its original and in excellent condition.

thanks,
Nathan

i don't know...but mole asses work great!

I tryed the molassis thing, and I didn't think it worked well at all. Maybe the tank is to far gone...gonna go ahead and bite the bullet and use por15...

I think mole asses is making fun of your vinegar spelling... maybe not I've yet to try ...
What did work for me was some throughly cleaned gravel (rocks) put them in shake shake shake (like the KC and the sunshine song) Seriously, anything to abraid the rust off will work. I've heard of chains nails bolts etc. the trick is to shake the sh*t out of it for a long time and then throughly rinse all rust out... I used denatured alcohol (evaportes quickly) for the last rinse. hope that helps

i wasn't making fun! just having a little...

i don't know about the vinegar...of all the threads, and there are many, noone has ever tried it that i recall...

nsarge - do a search for "rust" "tank" etc - you will find a number of topics where we hash our our successes and failures...

lumbee - the POR-15 works great - if you want a less expensive version, go to Home Depot and buy a couple bottles of "the must for rust", it's in the paint section. it contains phosporic acid, the same ingredient that the POR kit uses and just about as strong.

but i do recommend the kit...it's very nice.

junkie out...

...I put the chains in with molassis...let it sit 3 days, and did plenty of shaking, and still got a fuel filter full of rust...like I said though, the inside of the tank is pretty bad, I may have been asking to much of a home made remedy...

The Works Toilet bowl cleaner works great, dump it in straight, shake it every 10 mins (the first time I did it for half an hour, the second time I left it in there for an hr), neutralize the acid (TUMS and Seltzer Water), dump, dry, fill with gas and your good! Any of these home made remedys probably won't get rid of all the rust, so its still advised that afterwards you coat it or use an inline fuel filter.

I used molasses to great effect!
Had a moderately rusted CB350F tank, so much that it clogged the idle jets.
I used a regular sized bottle of it.
filled the rest of the tank up with warm water,
shook it about to mix.
Let sit for about 2 days, checking and shaking periodically
Dumped out molasses,
rinsed with water and found a beautiful bare metal tank.
Too bad it flash rusted very quickly, had to do it again.
2nd time I was ready to coat the inside of the tank immediately after rinse
SAE30 oil plus a little gas to thin it ( to get it to slosh and coat the inside)
Installed inline filter ($3) and was ready to roll! woo hoo!

I took a piece of speaker wire, and tied a few random sized bolts to it -and thru it in the tank , along with some PB BLASTER mixed with alittle WD40 & some Works cleaner. My rust was very light, so it wasnt all too bad. Alittle shake here and their ,and all was good.

I gave it a spray of WD40 once a week while it was sitting in my basement to prevent new rust from forming -and it worked like a champ !

My tank was very rusty (dad said it had stalagtights (sp)), but used the molasses first, left it in for about 12 hrs I think, had some result, but wasn't fast enough, so next I put some "the works" and water in, which was faster, but didn't leave it long enough. Fast forward about 2 months, and I did the works again, about 4:1 4 parts water, filled it to the top and monitored it for about 20 hrs. I left the tank full enough to take the rust off the bottom of the cap. I think it will have ill effects on your petcock, so watch out. It's also hard on paint (took about a 1/4" ring around the tank mouth and softened it , so I just pulled it off. I think it worked it's way under the paint there) Also, watch out for flash rust. But I now have a nice and clean tank.

Hey Lumbee, if you don't really need to coat the tank you can purchase the "Metal Ready" tank prep solution separately from the POR15 people. I believe it is a phosphoric acid based product which will remove all of the rust and leave a phosphate coating. I used the POR15 kit on my RZ but that was only because the tank was actually leaking. I have never coated a tank which was solid and didn't leak. All of their components are available separately.

cbjunkie · « **Reply #11 on:** August 03, 2006, 02:08:57 pm »

the Must for Rust i reffered to previously is WAY less expensive, and, basically, the same thing as the POR de-rustifier.

Lumbee · « **Reply #12 on:** August 03, 2006, 02:11:42 pm »

...just bought the kit this morning...I may just use the prep part of the kit first, and save the liner for another tank, as the one I have does not leak...

Yeah, I probably should have mentioned that it is kind of an expensive approach to the problem.

cbjunkie · « **Reply #14 on:** August 03, 2006, 02:51:59 pm »

i don't think anyone would argue with that, but i think there are plenty of us buying old tanks on Ebay, or inheriting these ancient machines from POs that lost interest years ago that find ourselves in need of serious help when it comes to running them, cleaning them, sealing them...
etc, etc.

have you ever had to do one?

Won't do much, won't harm either. The acid is to weak. To effectively clean out the tank you need Phosphoric acid. There are kits kile Kreem on the market that will effectively remove rust and put in an new (epoxy) protective layer. I have done it, works like a charm.

cbjunkie · « **Reply #16 on:** August 03, 2006, 03:02:31 pm »

whatever you do, don't use KREEM.

Luckily for me, no I have not had that pleasure. Both the Norton and the 175 have relatively pristine tank innards.

What went wrong with your tank?

cbjunkie · « **Reply #19 on:** August 04, 2006, 10:17:10 am »

i haven't used it.

i have had a tank that someone used it on, however and would never do it myself for that reason...it peels, tears and underneath guess what?

more rust.

i know all the arguments for "doing it right", but, frankly, after using the POR-15 kit i would never go back.

You are correct, if you don't have the tanks spotlessly clean it will do that. Mine has is still fine after 8 years.
Tell me more about this POR-15.

cbjunkie · « **Reply #21 on:** August 04, 2006, 10:39:03 am »

you won't need it unless you get a tank that has scale rust in it, or pinholes

the 30 dollar kit comes with three? stages one of which is a phosphoric acid based rust-eater - a similar product can easily and cheaply be bought at Home Depot under the name "Must for Rust" - the two are remarkably, almost suspiciously, similar and basically chemically trasform and freeze the rust.

once this is completed and cleaned from the tank, assiduously, and the tank is dry, bone dry, the last stage is the coating. unlike KREEM the POR coat is a chemical bond with the metal of the tank and forms a hard silverish interior that is really pleasing after you've been agonizing over chunks of rust in your float bowls.

the silver coating goes in with enough viscosity to fill over pinholes. i had large enough holes that i epoxied them first and then PORed over that, just to be sure.

google it. it's worth a look if you have a tank in bad shape. if i had to do it again i would check to see if i could get the last stage separately and use the Must for Rust as an alternate first stage.

hope this helps,
junkie out...

...I havn't used Kreem, but like junkie said, I've heard the same stories from others...but only good things about Por15...heres the tank kit...

Stop playing games with it.

Go to Ace Hardware. Buy one gallon of Muratic Acid. Done right, you will have a perfectly clean tank in about 2 hours.
Read all cautions. Be very careful. Highly toxic and very nasty stuff for a very nasty job.

cbjunkie · « **Reply #24 on:** August 07, 2006, 08:31:58 pm »

bodain - what does a gallon of muriatic acid cost?
