Topic: Update - Esprit Rust Remover CONCENTRATE? $38.50 for 5 Gallons

[chewbacca5000]

Yes, Evapo Rust does recomend heating their liquid.  I like Espirt better since it is only about 1/2 the price of other products.  I like being able to add hot water to Espirt and not have chemicals in my cookpot or stick up the house.


Being able to completely fill a 4.5 gallon tank with Evapo Rust at $20 per galllon would cost $80 your Espirt product is right around $40 for 4 1/2 gallons.  To me being able to add water plus IMHO.

Once I am done I will dump out my cb360 tank into a 5 gallon pal to derust other stuff nuts, bolts, battery box etc..

Evaporust states that the optimium operating temperature for their product is 55-65 degrees fahrenheit.   If the other stuff works regardless of temperature I maybe interested in learning more about it.  $#8.50 for 5 gallons sounds like a good deal even if you have to mix it.   So far I have used muriatic acid, and Evaporust.  Evaporust will always win hands down over the acid.  But Espirit has me intriqued that I want to learn more about it.

Sorry Spot45 I must have mistyped Espirt is about $8 per gallon vs Evaporust which is around $20 per gallon.  As far as temperature heat helps with many chemical reactions and acts as a catalyst to speed things up.  You could probably get away without heating the water up first, but it may take longer.  I have used Evaporust at 60 degrees and for me it took close to a week before all the rust is gone.

In a dry rusty tank not coated in a layer of 30 year old varnish I bet Espirt and boiling water could derust a tank in as little as a few hours.  The gas cap without any varnish derusted almost immediately.  Here is some pics after about 24 hours soaking.

Johnie I tried my best to get one on the top of the tank using a mirror.  If look really close you can see the Espirt did it's thing all the way to the top of the tank.

I'd recommend Espirt over similar based chelant-based rust removers like Evaporust as I think it does a good job in terms of performance and value and is reusable.

Looking clean in there Kyle. See a couple spots still in the second picture still,bet a dollar its still a little varnish. May a screwdriver or something could be used to scrape that a little to help break it up before a little more soak.   Eric

[chewbacca5000]

Your right Erik still more varnish.  If it was rust the Espirt would have gotten it.  I took a chain and sloshed it around to break up the remaining junk and let the Espirt do it's thing.  I am pretty happy with Espirt and will buy this over evaporust in the future.

A pic of the junk that was in the tank.  Nasty!

[Esprit Performance]

Kyle,

I am pleased with your results and I appreciate the effort to document the rust removal process with the Esprit Performance rust remover concentrate; you did a fantastic job!

If you plan to store the tank for a while I would 'slosh' it with Marvel Mystery oil. When it comes time to use it, I would add MMO every tankful.

I have also added a link to my Rust Depot home page since there may be other Honda enthusiasts who can benefit from all the info in this forum.

Thanks again!

[Johnie]

I agree...it is looking good there Kyle. Thanks for the report and pics.

[Esprit Performance]

Has anyone else tried removing rust with these types of rust removers?

I heard from another customer who had problems with removing rust in his tank. The problem was due to the coating of 'varnish' inside. Apparently the chelant based rust removers will not remove rust unless the 'varnish' is removed first. If not, the rust remover is blamed as ineffective, which is clearly not the case.

I would like to hear about the easiest, non hazardous approach that can be combined with the rust remover and offered as a 'package' designed specifically to remove tank rust.

Thank you for any advice / input.

Is the Esprit rust remover available locally ? and what's the Best way to remove all the varnish prior to using this new type of rust remover ? I want to completely remove any varnish that'll interfere w/ the de-rusting action of it.

[grcamna2]

Does anyone know the best product to use..that would be recommended by the manufacturer,that will prep the tank and clean out the old varnish the Best before I use Esprit rust remover ? I don't want to break down the chemical strength of Esprit w/ the wrong varnish remover.Where do I buy Esprit rust remover locally in Atlanta? Tractor Supply ?

Do you need to use a product like Red Kote tank sealer afterwards? or after the process it is good to go with out the sealer?

Hi Tony,

No Espirt is not available locally, but is easy enough to order through www.rustremoverproducts.com.  Lee is very helpful and has fast shipping.

As for varnish removal your plan of attack will depend on the quality of the paint on your tank.  Carb cleaners like autozones value carb dissolve varnish instantly, but will remove paint as well.  If your paint is very good avoid acetone or carb cleaner all together and use boiling hot water and some mild soap like dawn.  You may try simple green, but I am not sure if that is paint safe or not.

Fill your tank with the boiling hot water and some dawn and let set for several hours to a full day.  If you don't want to boil the water you will have to wait much longer for the varnish to dissolve.

After that dump out the tank give it a good rinse with clean water and add your E-Spirit solution.  Try to follow directions on the bottle as it will help with rust removal.  Heat turbo charges the derusting process of these products.

Most of the rust was gone in 12 hours with the rest gone the next day.  The CB360 tank was an extreme example.  Most tanks won't need so much prep.  If there is only mild varnish you can just dump the ESpirt in.  I like to remove as much junk first so I can reuse the Eprit and get the max life out of it.   If this is not a concern you can probally just heat water add the Espirt and forget about it.  I like to reuse the product.  Good Luck!

Chewy! This is great info, thankyou! I know that both Bill and I have nice paint jobs on the tanks and dont want to mess them up, so the carb cleaner is out. I have heard of people using BB's with the hot water/soap solution so they wont dent the tabk with nuts and bolts.

But as for after the Esprit I read about the MMO, but do we have to use something like Red Kote after it? Or do we not have to worry about using a product like this at all to seal the inside after.

Thanks again!

Tony,
     I'm glad someone was finally able to answer that..,this is all new to me also.
  If it was me...,I'd prefer to keep the tank full w/ fuel as much as possible to keep it from rusting and give it a light coating of oil before putting it away for the winter(if you even plan on "putting it away" ;but just use the rust remover treatment and use the tank without lining it w/ Red Kote or similar sealing coat.
I've found that if the M/C sits in the direct sunshine regularly...and then cools off at night, well that is a large change in temperature that causes the tank to develop condensation inside(water)and that is one of the reasons tanks rust inside so much.I think when they sit open w/o fuel in them water vapor collects in there also.
When you park your bike, try to park it in the shade or in a cool spot w/ shade..or cover it from direct sun to avoid too much condensation at night when it gets cooler.
I imagine the best way to keep the inside of the tank from rusting is to fill'er up every day and keep it filled.I think when a tank is lined w/ a sealer it has a useable life(not sure how long..it depends on the prep. before you line the tank)span and after that the lining will start to lift a bit inside the tank and can clog your fuel system...,that's why I'll hold off on lining my tank w/ Red Kote this time around.I used to line them All the time w/ no short term negative effects that I knew of..again,it all depends on how well you prepare the interior of your tank;it HAS to be 100% dry for 100% adhesion..and that takes quite a while to do,most guys don't have the patience to wait almost a week before applying the coating...and then wait another week for it to cure up well enough before they pour fuel into it & begin  to use it.

Tony,

I would have to go with grcamna2 and say no to coating unless the tank has pin holes or so much rust gets removed that you feel the metal is too thin.  I like my tanks without the coating whenever possible.  The other thing for long term storage make sure the cap is open so air can circulate in the tank if empty.  The other option completely full with gas.

[Guns_Up]

Awesome thank you guys for all the info, this has been the solution/information that I was searching for. I think that I may have to give this stuff a whirl.

I have recently attempted to remove the thick varnish in my Triumph TR-250 (car) to get down to the rust so it could be removed. I used heated water with dish detergent then a mix of gasoline and drygas to get rid of the moisture afterward.

When I looked in the tank, I didn't see much difference. The varnish is a serious barrier to the rust removal step & I'm wondering what has worked best. If anyone has any ideas, please share them.

Thanks, Lee

Lee did you heat the water to a boil?

[Esprit Performance]

I didn't boil it, but left the tank in the sun for hours until it became almost too hot to handle. I have since been running the engine w/ 2 fuel filters in line w/ fresh fuel and MM oil. The fuel does emulsify the varnish but deposits it into the carbs and intake. You would not believe the thickness of this varnish! It was probably 1/8 inch thick on the bottom. I will drain the fuel and use boiling water and detergent (I understand Dawn works the best). Once the varnish is gone I will remove the rust with Esprit rust remover and document it like you did; that was a great writeup.

[Hasenkopf]

just as an update, my stuff worked ok, a little cheaper that evapo rust....maybe worked just a bit better, I should have filled the tank  all the way though.   good stuff!
