Eastwood Rust Dissolver Qt is rated 3.6 out of 5 by 60.
Rated 5 out of 5 by from Great product, used it many times. I bought this product to restore my 1970 VW beetle 9 years ago and have used it on other small projects since. I have used both the gel and non gel versions of the product. The Gel works as well as the non-gel product. The only thing is with the gel you must remove all flaky and scaly rust first. Don't expect this product to do all the work for you. Like others who gave poor reviews, I learned that the hard way when I first started using the product. I got better with it the more I used it. Remove the heavy stuff first. Works best after that to remove cancerous metal pitting in vertical areas and areas where you need to treat underneath or inside. Cover the area with a paper towel to keep the gel from drying out. If it does dry out it will leave a yellow stain. But you can clean or sand the metal again and retreat if that happens. I also used a paper towel covered with plastic with two sides taped. This allows some moisture to escape but at a much slower rate. The key is to just keep the gel wet. If it starts to dry just reapply. The non gel version is best for small parts, flat areas and bathing parts. You can you can let debris settle to the bottom of your bathing container, filter if needed and reuse. I put used product into a separate container for later reuse. When you are down to bare clean metal it should leave a zinc coating. Clean off remaining product with water. once dry I then wipe lightly with acetone then apply etching primer and paint where required. I've had no problems with returning rust since using this process. Hope this helps someone.

Rated 5 out of 5 by from Awesome product. Unbelievably effective. I purchased a gallon a few weeks ago to test it out on some parts I was going to throw away as they were rusted and pitted so bad. I let them soak over night and came back to brand new looking parts. Virtually ALL the rust was gone. I'm buying 2 more gallons right now because I built a small trash bag lined bath tub for bigger parts I want to save. Make sure to use protective common sense, latex gloves, don't breath the stuff and wash the parts thoroughly, etch them before painting. I highly recommend the product.

I have a cast iron fountain with rust on it.  What would be the best product to clean/stop rust as the effected area will have water running over it after it is treated and painted (other brand’s products have rusted through very quickly).  Thank you

Asked by: Jenn22
This product is designed to be applied to the surface and remain saturated on it for several hours. Then rinse clean with water and it should leave you with clean bare metal that you ca then apply your primer and or paint to once dried.

Half of my van roof is rusted, some of the rust won't even sand off. What product should I used to remove/reduce the rust? Are there any special instructions for a large flat area and will it affect the existing good paint?

Asked by: Wayne
The best product to use would be our Platinum rust encapsulator. You can brush or roll it on but spray on will give you the smoothest finish. After this is on you can paint over it with auto paint.

Can this product be used to devolve the rust in my cars cooling system ?

Asked by: Mark
This product will dissolve rust on the cooling system, however this will not prevent future rust.

I may have missed it, but how is the Gel or NON Gel applied? I saw that you can't use a squirt bottle, I was going to use a pesticide sprayer myself. How does one apply this product, thank you

Asked by: CoachK
This product must remain wet on the surface to work. Generally the liquid form is best for soaking parts in while the gel will get applied and sit on the surface while it works.

I have rust bubbling starting in the dogleg area if front of the rear wheel. Can I use this on the inside of that area to stop the rust? Also-if that will work-can I use an adhesive to attach a piece of metal on the inside of the rusted area?

Asked by: William
Unfortunately the area you are referring to is not going to be accessible to kill the rust. The bubbling rust is coming from the inside where the quart panel and outer wheelhouse are welded together. This area sadly requires the rusted area to be cut out and a patch panel welded in.

Can this product be used to remove rust from the inside of a motorcycle tank? Does it go in full strength or mixed with water?

Asked by: Bill
While we have never tested it in a tank it certainly could work and goes in full strength followed by acetone to rinse. The better option would be our Gas Tank Kit which is specifically designed to work inside a fuel tank.

What would be better to use on a truck frame and axles that have moderate rust from being stored outdoors for a number of years, gel or liquid the truck is still in one piece and the affected parts would be treated in stages as I'm able to disassemble?

Asked by: Ursusarticus
The gel is the best option to help keep the area wet. Another great option which would skip past a chemical repair would be our Blast Out Of a Bucket kit. Simply media blast the rust off piece by piece as you take the truck apart. Then simply prime to protect the bare metal.

Is this product suitable to remove rust from inside of motorcycle gas tank ?

Asked by: Wrench
While it technically could we have a better product for the task at hand. Our Fuel tank repair kit will take care of the rust along with a new seal coat to protect your tank in the future.
