OXPHO-BLUE® Reviews & Ratings

Originally developed for the occasional bluer who is not equipped to completely polish a gun prior to bluing, Oxpho Blue - because of its ease of application and remarkably superior results - has become a favorite of the professional gunsmith as well. With Oxpho-Blue, all you need do in most cases, is dampen a piece of cotton flannel and give the area a good rubbing. The chemical goes through the oil on the gun, removes thin rust and blues the steel underneath. No after-rust. For looks, the final finish was not intended to approach the beauty of the well-polished, hot-blued gun. It has developed, however, that in the hands of a careful craftsman, not only is the Oxpho-Blue finish beautiful, but it is also more durable and weather resistant than any other known chemical finish. Oxpho-Blue has other outstanding features worthy of note:

Absolutely no after-rust.
Phosphate-like surface forms under the blue.
Rust removing qualities of the solution, making it unnecessary to remove mild rust in the usual manner.
"Wetting" characteristics of the solution, giving it the ability to penetrate oil, dirt, etc., on the surface of the gun; blue the metal underneath; remove rust and dirt; leave the gun blued and ready for oiling.
Beauty and high durability of the finish: vigorous rubbing with No. 0 steel wool is one of our favorite application methods - the more rubbing, the more brilliant it comes and, since abrasion is part of the process, normal contact from gun cases, brush and clothing won't wear your bluing. (Note: It is possible to get a surface so dense with Oxpho-Blue that water will puddle on it!)
For Neighbor Kid and Mr. Average Sportsman, a beat-up gun can be made to look quite presentable by following this recent application technique; dampen a shoe shine cloth with Oxpho-Blue and blue the gun with a shoe shine motion - without taking too much trouble to remove old dirt, grease, rust, etc. This particular gimmick actually obsoletes all other kinds of bluing for retail sale, for any youngster can make his old man's gun look quite presentable. For gun club members, neighborhood shooters, etc., one bottle takes care of the lot. (The rub-on features works wonders on tools and instruments which have been blackened and show bright along the edges: just dampen a cloth with Oxpho-Blue, rub the bright areas briskly and they are as black as before, but tougher.)

SPECS: 4 fl. oz. (118ml), or 32 fl. oz.

Oxpho blue

Well I don't write a lot of reviews but I thought this product was worth a review I gave it five stars because it wouldn't let me give it a 6 easy to use easy to blend with other blue this is my number one go to for gun bluing I won't use anything else

Great cold blueing

My 1860 Army by Pietta needed to have the loading groove on the barrel lug opened up so paper cartridges and conical's could be loaded. (Pietta makes this area too shallow for them.) A couple of years ago I went through all the different files and grades of emery cloth finishing up with #0000 steel wool. The cold bluing (a competitors brand) never looked good. I took the surface areas back down and used Oxypho Blue this time and nearly had a good matching blue on the first application. The color was quick and easy. It took two applications. Follow the instructions and you will not be disappointed at all in this product.

Excellent bluing product!

This is my go-to for bluing gun steel. No need to have hot or cold water sitting by. Directions are pretty simple, I have found this process most effective: 1-clean/degrease surface with bore cleaner and #000 or #0000 steel wool, both at the same time. 2-dry surface 3-dip cotton ball in oxpho bluing solution 4-dab on a fairly 'wet' coating of solution, and rub in until absorbed in metal/cotton ball. 5-either dry off excess with new cotton ball, or go ahead and rub in solution with #000 steel wool. 6-repeat steps 2 to 5 for additional costs, I found after about 3 coats I get a nice, rich dark black finish. I let the solution sit or cure for a couple hours, room temp. 7-lastly, final wipe clean with bore cleaner and then coating of gun oil. Again, I can't say how nice of a finish this leaves. Absolutely great! Hope that info helps anyone interested!

Awesome

I used this to help redo the finish on my 12 year old 870 Express. I followed the simple directions, and redid the last coat 4 times and the gun came out with a nice even black finish. I coated it next with a heavy coat of Rem Oil and then wiped it down and the finish looks almost brand new. I am very pleased and will make sure to keep a bottle handy in my cleaning kit. I mostly have field grade hunting arms so this is just what I need to keep the finished up after they see use and abuse.

Amazing stuff.

Why haven't I tried this stuff before?!? I have an old Remington model 12 that someone had gotten quite aggressive with the abrasive removing rust and left parts of the little .22 almost white. I went to work with the Oxpho-blue liquid and working small areas, lots of elbow grease and burnishing with #0000 steel wool between applications, it looked like beautiful aged factory blue in 2-3 "coats". I kick myself for not trying this on an old 1906 Winchester that I had hot blued. I could've restored the factory finish rather than making it look "too new". Fantastic product! Easy to use, forgiving of technique and looks great. Five stars, only because I can't give it more.

Best "Cold Blue" Product I have used.

Oxpho-Blue was purchased, not gifted. MY EXPERIENCE: In the past 3 decades I have "cold blued " barrels,.receivers, slides, frames, hammers, pins, fasteners, etc. Still, I consider myself a novice, NOT a professional. Some "cold bluing" products work better than others for various reasons (e.g., ambient environmental conditions, pre-blue preparation, the steel alloy being blued, cleanliness, contamination, skill and bluing products' "niche" techniques, etc.). All brands have satisfied and dissatisfied users ... for reasons that are mind numbing. Based solely on my personal experience, the ONLY "cold bluing" product that I will/do recommend is Brownell's Oxpho-Blue. I have always achieved acceptable, and often superior, finishes. I cannot say the same for other Brands. RECENT: This past weekend I spent 12+ hours preparing a 1911 steel slide for bluing. Sunday afternoon i cleaned off my bench/work area. Instead of O-B, I had purchased Brand B, another well respected "cold bluing" gel product. A "shooting buddy" strongly recommended Brand B as " a much better product ... well suited for your job." My research indicated that it IS popular and VERY highly rated by lots of HAPPY users. MY BOTTOM LUNE: After 6 hours and 3 failed bluing attempts, I stopped and stepped back. I re-read reviews, re-watched on-line instructions (including videos by the manufacturer) and re-evaluated my work/results. I WAS CLUELESS. NOW WHAT: 1) 20 minutes ago I reordered Oxpho-Blue from Brownell's. 2) The slide for the 1911 is prepped and ready. 3) Relax: It is like Christmas ... waiting for my O-B to be delivered. 4) Remember: "If it ain't broke don't fix it." 5) Remember: "Friend, better is the enemy of good enough." PRODUCT ISSUES: What's wrong with O-B? I am unable to identify any product things to fix/improve Packaging/container options need to be evaluated. An acidic product that is affected by oxygen in air, once opened, the O-B quickly destroys the bottle cap's cardboard-back/thin-metal-seal. Sometimes, if I use the "appropriate" amount of plastic food wrap, the bottle and cap will seal. Sometimes. IDEA: I have purchased two lab-quality, plastic bottles with SS application tips (these use soft, positive-seal end caps), and leak-tite bottle caps. I will transfer O-B to my new containers and check for function and leakage.

Good stuff

I bought a 10 s&w Police hand gun turn in some holster ware some lite rust a little of Brownells blue & 0000 steel wool and wipe down with gun oil. Savings of about $300 bucks

Great Stuff to Use

I have used this product on various guns from spot touch-ups to full shotguns. Couldn't be happier with the results. Proper prep and cleaning seem to help. Heating the metal prior to application and coating the metal in heavy oil for a few days when done has lead to some excellent results. One of the best is when I restored a gun that had been in a fire and then left out in a shed for 6 months. The before and after photos are attached and are quite amazing to show what you can do with OXPHO-BLUE. It is a gun product I always keep on hand now.

Great product

I used this product to revive a Winchester model 1906. It was in pretty rough shape with much surface rust and grime. After careful cleaning and removal of the surface rust, some sanding and proper application of the Oxpho-Blue the pieces turned out beautiful, better than I hoped for. This was my first attempt at re-bluing a gun which looked hopelessly ruined by negligence and the ravages of 100 years. I will definitely buy this product again. The 4 ounce bottle was sufficient to do this one gun. I will be buying the bigger bottle next time.

Excellent Carbon Steel Cold Blue

This is an excellent cold bluing solution. I've used it to touch up many firearms with excellent results! I even used it on a ring I made to practice filing techniques. Finish is very important! The finer the finish, the better shine you can get by using the #0000 steel wool. Excellent videos as well as the instructions on the bottle.
