Iron OUT Rust Stain Remover Spray Gel, Remove Rust Stains in Bathrooms, Kitchens, Laundry, and Outdoors, 24 Ounces

I have a white plastic fence that looked just fine until I replaced the sprinkler pump 2 years ago. The previous owner had set up the sprinklers the easy way, i.e. put in a few heads and throw water everywhere, including against all the fences. The result was an orange and white mess.I tried the pressure washer, and it got most of it, but in several areas, it wouldn't come off, so I got on Amazon and started looking for a solution. They had a few inexpensive options, so I decided to try 3 different products.Iron Out Spray GelWhink Foaming Rust Stain Remover SprayEcoxall Oxalic AcidFirst off, all 3 will get the job done, but they have their differences. The acid came without instructions, but the instructions on the other 2 bottles are completely WRONG! Both say to spray it on, leave it there for about a minute, wipe it off, then rinse and repeat if necessary. I tried their way, and if you do that, you're going to be doing a whole lot of "repeat if necessary" and burning a bunch of elbow grease.Here's what I found works best with all 3 products. Spray it on, walk away for at least 30 minutes, come back, if there is any rust left, repeat the first 2 steps. No wiping necessary. They all leave a slight residue, so you might want to rinse it off, but it really doesn't show up on a white surface. basically, if you can pull the trigger on a squirt gun, you can get the rust off of anything.I tried them on a plastic fence, an aluminum pool cage, and a stucco wall with latex paint. The painted wall was the easiest to clean, the pool cage, the hardest. Here are reviews of each product:Iron Out - If I had to pick a favorite of the 3, this would be it, at least as far as the whole "get the job done in the least time" thing goes. In some cases, while testing, it would have the area completely clean before I could get the other two applied. It's not oily, but has sort of the consistency of oil, so it "clings" like it says on the bottle. The cost wasn't much, but only if you're looking to do a small job. If you've got a big area to clean, keep reading...Pros: Works fast, "clings", It works!Cons: Price, the lid is locked on, so you can't reuse the bottle.Whink Foaming Spray - I wasn't sitting there with a stopwatch, but this seemed to be the slowest of the 3. Having said that it works just as well as the others. The "foaming" part is fairly thin, but it's there. I found it to work best on flat surfaces, rather than walls, but will "git 'er done" regardless.Pros: Foam, It works!Cons: Price, slower than the others. The lid is locked on, so you can't reuse the bottle.Oxalic Acid - This is a powder that has to be mixed with water, and it doesn't come with any instructions, but you can find plenty of videos on You Tube. At first, I basically took 12 ounces of water and tried to see how much acid I could add before the crystals would no longer dissolve. It took about 5 tablespoons. I used a small brush to apply it at first but put it in a spray bottle later on. It will work either way.Later I mixed a batch with only 2 tablespoons of powder, which predicably did not work as well. I'd suggest using 1.5 ounces (by weight, not volume, a little over 4 tablespoons) in 12 ozs. of water.This is definitely the cheapest way to go. I did the math, and you can make about 10 - 24 oz. bottles of this for the price of 2 bottles of the others. You do have to buy a spray bottle, but if you have a garden sprayer, you can use that.One other thing, you might want to use a mask when dealing with this stuff. It's not just small crystals. It also has a fine powder that's there as well. When mixing it, if you shake the spoon or the bottle a bit that powder can get airborne. Been there, done that. It will definitely irritate the nose. Also, once it's been mixed with water, and you set your spray nozzle for a wide application, you'll get a fine mist that floats in the air. Breathing it will irritate respiration as well. Done that, too. Don't be me.Pros: Cheap, works pretty fast, It works!Cons: You have to mix it (time and irritation).Check out the photos. They're sort of self-explanatory. Also, keep in mind that I'm very lazy. The only muscle used in the making of these photos was my trigger finger.

OMG! This stuff is AMAZING! I have a plastic outdoor shed that gets sprayed by my well water irrigation system daily. Over the years it built up a bad "rust" layer, I tried blasting it with a pressure washer (green nozzle) - nope, barely made a dent. I tried scrubbing with Spray Nine, nope - no effect at all. I just sprayed this stuff on and WOW! Before I could even finish spraying ALL of the rust was GONE, completely! And as a side benefit I have plastic door handles that had oxidized and I noticed when I sprayed them it removed the oxidation (I'm in the process of removing oxidation from some plastic deck boxes using other products, I'm definitely going to test this and see if it works!). I wish I had taken photos of before/after to share - but trust me, this stuff REALLY works! I just ordered 2 more bottles!

I sprayed this on the door of my white truck where rust stains from a mirror going bad left a large dark red streak down the whole door. in a few minutes it was half as dark and the next day it was white again, i rinsed it off with the hose and can not tell there was ever a problem. i sprayed some on my black rims where brake dust had also turned the wheel red, it is much better (almost black again) I believe if i scrubbed it and maybe tried another few squirts it would clean up like it never had that rust look. I am lazy and very satisfied!

Had to get these yellowish orange brown spots on my marble countertop and nothing was working from iron skillet. This product took 2 to 3 times and that third time was a charm. Remember, some surfaces need for this product to sit on stain a little longer than recommended on the bottle. Instead of waiting a few seconds; because it didn’t work after I waited 10 seconds then wiped it. I then did it over & waited a full minute and that’s when I had the best results.

Had a badly iron stained toilet bowl and tank. The tank was terrible.Drained it, gave it a good spray with this amazing product and left it while we all had supper.Came back and it had all gone, no more stains!Worked perfectly.Flushed with clean water, and it was good to go.The chemical is harsh so be careful.Five star from me!!

Our water system is from a well, which is great, no water bills. However, the water has a lot of iron in it. With the first use of this product is removed almost all of the discoloration caused by the iron. The toilet, shower and sink are super clean and almost look as if they were new.

It did not remove rust stains. Also, not sure why it lists “Gel”, since it sprays a regular thin/watery stream. Normally a “Gel” is thick, and adheres to the surface; this does not.

Somehow my washer transfered rust onto my white towels and I thought they were ruined. Before throwing them out, I thought I would give this a try. I didn't see a ton of people saying they had using it for laundry even though it says it's safe for it, so it was a bit of a gamble. All I can say is WOW! I sprayed this stuff on the spots and they were literally gone within 5 minutes!! Washed as normal and they look good as new. Definitely recommend!
