All the distributors have. Runs around $45 per/gal
Seams kinda expensive. You guys think its worth it. Long and short if it’s better its better and if I dont have to mix it that’s a bonus. Maybe I just answered my question
That’s only 6oz per gal. I don’t think mixing it a little stronger would not make it work. I’ve just never had any luck with it on anything except wood.
I tested it back to back with a couple of other products on removing mud several months ago and was about average though it was the cheapest of the things I tested.
@Grizz and I have both tried on rust and it’s from different suppliers and neither of us have ever had any luck with it. Not worth the aggravation when we both have local chems that do work although a little more expensive.
We’re either doing something wrong or we have different rust here.
I completely agree with you I hate messing with it but I have had alot of success strange I guess. But you should do what works for you. I’m goi g to order some f9 and see how I like it.
When Chris at @SchertzServicesLLC had that big commercial rust job he cleaned PWS out of F9. I’m sure that if he could have done with Ox he would have saved a ton. But I think he was happy with the results with F9 and it’s a known quantity.
This is why I’m here going to order some tonight.
@squidskc swears by Ox
I wish I could get it to work. Got like 50 lbs of it and only rarely use when I’m doing decks.
It has worked well for me the house I post was done with ox
I know. It looked great.
Some rust stains I’ve encountered Oxalic won’t even lighten. Even at 2c per gallon. Others have been like magic at 1c per gallon. Just the way the cookie crumbles I guess.
Im going to keep trying ox first if already have some mixed up @Maelstrom how are you using it? Sounds like you use it alot.
Maybe you do have different rust. I did apply mine with a brush instead of spraying it I also use hot water rinse. Could have something to do with the water hardness or ph
I think it just depends on the rust and what it’s on. Oxalic works great on vinyl. It even works on some rust on concrete. I think it depends how long the rust has been there and what the rust is from. Oxalic is a lot cheaper so worth trying first. F9 blows it out of the water and I would imagine it’s because Phosphoric is a lot stronger than Oxalic. It really blows it away on concrete. Some of the other ingredients might help too but I think they’re only surfactants.
We have real soft water around here
Not everything that looks like rust is rust, and only certain types of rust are able to be modified by oxalic.
Confused yet? Okay, here is the thing. Think about where rust comes from, and what it is. In theory it’s iron oxide…but now a days are people really using a ferric metal for cable boxes and the like? It’s not likely.
Oxalic is good at old school cleaning of old school metalic rusts. NEW metals don’t contain only iron, yes there is iron in steel but again, how much steel is being used without other weird metals and alloys? So what we have now is a new generation of it looks like rust, but it’s not my grandpas rust.
If oxalic doesn’t work you need to try a different acid. F9 is a good product but holy crud are you bringing an AK-47 to a butter knife fight in many instances. I encourage you to explore other acids before you bring out the F9 big guns.
Hmmm i guess a new age rust calls for a new age acid.
Going to try gluten free no GMO organic citrus acid next time.
Might as well rub a lemon on it. Well, an organic, gluten free, non-gmo lemon.
