Brownells Oxpho-Blue Liquid Gun Blue, Cold Bluing Solution, Gunsmithing Tools Maintenance Cleaning Supplies, Professional Grade, 4 Fl oz. (118.2 mL)

I originally bought this to address some surface rust on a Ruger 10/22 barrel. The barrel wasn't damaged beyond saving, but it had enough rust speckling that I was trying to decide whether it could be restored or if replacement was the better option. I'm glad I tried Oxpho-Blue first. I'll be the first to admit that refinishing metal isn't my strongest DIY skill, so I wasn't expecting professional results. What surprised me most was how forgiving and easy the product was to use. After removing the rust and prepping the surface, I applied roughly six coats. The solution went on evenly, blended well between applications, and gradually built up a finish that looked far better than I expected. The end result wasn't identical to a factory hot-blued finish, but it was close enough that the barrel went from looking neglected to looking presentable again. From a practical standpoint, it completely saved me from having to replace the barrel. A few things I liked: easy application process even color development good results without specialized equipment effective for touch-ups and restoration work affordable compared to replacing parts It's important to keep expectations realistic. Cold bluing is not the same as a factory blued finish, and I wouldn't expect it to match the durability of a professionally applied coating. But that's also not really the point. For me, this product filled the gap between: doing nothing and living with rust replacing an otherwise serviceable part paying for professional refinishing If you have a firearm with light surface rust, worn bluing, or cosmetic damage, this is an inexpensive and surprisingly effective option to try before moving on to more drastic and expensive solutions. In my case, it exceeded expectations and gave new life to a barrel that I was seriously considering replacing.

Very easy to work with and really restored my rifle to new.. Simply remove the rust with a 400 grit emory paper, wipe clean with a cleaner (like alcohol) before applied the bluing Solution, let it then dry for a minute and burnish with a #0 steel wool. Repeat the process if necessary, I applied it 3 times minimum. At end apply CLP mil spec to seal the newly applied area.

I’m very pleased with this cold bluing solution. I used it on a tool post nut and handle I machined for my lathe. It took me about 20 mins all together to get the result I was after. Just be patient and burnish as instructed. I was more than pleased with the results after prepping the parts with brake cleaner.

I contemplated giving Brownells Oxpho-Blue five stars, but so far, in my opinion, no one has ever produced a cold bluing chemical process that deserved it. Don't expect results that look like a well done hot blue finish from a boiling salts process, but Oxpho-Blue is great for touching up. I found Oxpho-Blue to be significantly better than Birchwood-Casey's Super Blue at producing a deep blue-black color. Just in case you are considering doing some hot bluing... DON'T, unless you are a serious professional with the facilities and skills needed to work with very dangerous chemicals boiling at almost 300 degree F and handing hazardous waste. Oxpho-Blue is the best solution you'll find short of hot bluing. A few pointers... take no shortcuts in cleaning the part first. Follow directions and apply with a VERY SMALL wrag - about the size of your thumb, otherwise you will waste the solution. What works best for me is to put a few tablespoons in a small open container that I can dip the wrag in. If you are bluing a large area, expect the first application to look awful! It will. Wipe it dry and reapply the solution, now rubbing and drenching the areas that didn't react the first time. Leave it wet for a while per directions. If you did a good job of cleaning, you will find that repeated applications will make the part darker and darker... Be careful that you don't waste the solution,,, use a SMALL applicator and it will go a long way. I used Oxpho-Blue to put a steel blue finish on curtain rods and steel C-Tables for our family room. The curtain rods have been up for almost five years and look great. I put a couple of coats of Min-Wax Finishing Wax over both and projects and they are very well protected and look great.

good product

Works great

I have a 1969 Marlin 1894 44 mag lever action rifle, that I accidentally ruined the finish on,had surface rust I tried using naval jelly rust removal it ate the bluing off my $2200 rifle made me sick,I bought this OXPHO BLUE followed instructions and my rifle looks brand new actually better than before I've put 30 coates on so far and it looks like a mirror,If you want to refinish a gun and make it look amazing and do it easy buy this stuff 💯 the best thing made for gun owners.

Thirty years as a professional gunsmith, I've blued lots of firearms the conventional way with bluing salts and heated tanks. But for simple touch-up work I used Oxpho-Blue. In many cases light oil could be wiped away and you simply dab the solution to the problem. It's really amazing. No alcohol cleaning needed, though it doesn't hurt to do so. After a minute or so rub the spot with a clean dry cloth. Want it darker, reapply. When done coat your weapon with oil. You'll be amazed how well it works.

Good product

I need more

Este producto es para pavonar. Es muy bueno en la mayoria de los aceros comerciales. Para obtener un buen acabado hay que dar varias manos: entre 8 y 10.

Worked like a charm, had an 870 magnum express receiver that needed some touchups, this covered everything up to near factory look!

Worked great, very simple to use for touch ups. Great price
