    Rusty stainless steel handrail

    Hi,

    I made this handrail from 304 stainless steel and now its rusty. Everywhere that i used a flap disc / sanding disc there is rust. Is it from a contaminated disc? Or by grinding did I destroy that chromium Oxide passive layer? How can I fix this?

    Cross contamination. A passivation solution such as citrisurf 77 should clean that up. I like to spray it on and than rub it in with a scotch brite pad in the the direction of the grain. I like to passivate all stainless prior to install and than once after. I think it helps to leave a smoother brushed finish. Here's an example after passivation. I did not do the glass rail. Just the staircase and rail attached to it.Name:  20170627_105836.jpg

    Wipe down with acetone.....neutralizes the iron oxides and then use a commercial stainless steel appliance cleaner.....

    Never use the same grinding wheel, flap-disc, etc, on stainless that you use on steel.

    If it from a contaminated disc can i clean the rust of then just grind consecutive layers off using a new disc for each layer?

    Maybe. You will contaminate the new disc when you clean off the rust and previous contamination.

    whats a long time? whats the environment like...

    stainless will rust, the best results are to completely dip and passivate. i only use even brand new flap wheels on stainless as a worst case. fleece or scotchbrite abrasives remove the back with out smearing it back it. even when using an ss wire wheel immediately follow with a fleece.

    Wipe down areas affected w/ acetone and then the whole rail with S.S. Appliance Cleaner......I've had this " problem " on almost EVERY S.S. rail job I've done.....Some how, some way iron oxides get on the product......Standard procedure on every "punch-list" when the job is completed/ inspected......Can get shop rags, S.S. Appliance Cleaner and acetone at Lowes or homey depot.........

    You might be able to buff it out with the right wheel and black compound.

    In future projects use one grinder Only for SS always new wheel at the start of a job. Mark the grinder SS only.

    Re: Rusty stainless steel handrail

    if cant be removed, use a burnisher witha fleece pad. its all you can do. come back in a month and do it again. and again until no more issue.


    in the future, everything. grinders, gloves, tungsten, wire bushes, wheels, everything, everything..... should all be kept separate and only used on stainless.


    my shop, i have a storage for stainless tools and when job comes up i spent an entire day cleaning the work bay and have a plastic curtain that drops to separate it from the other work. small handrail jobs are a shop clean then no other work until the stainless is out. stainless work cost allot for a reason. hope you charged accordingly.

    Oxalic acid is worth a try. It's found in Barkeepers Friend cleanser. BEHR PREMIUM® All-In-One Wood Cleaner #63 also contains oxalic acid.

    Re: Rusty stainless steel handrail

    First I would try buff and buff again as suggested. However, I assume that is a seam. Looks like it is. Looks as though the entire rail will need to me sanded in order to blend the finish. How much is there? And can just redo it, dust seem like finishes don't / won't match? Perhaps use mechanical connectors and adhesive.

    316 is better for outdoor stuff, I've used a mild steel wire wheel by mistake finishing a stainless sink for a restaurant, it rusted in about 3.5 seconds after they starting washing dishes,

    Just get a fresh flap wheel, sand it down, done, don't overthink it. Put some wax on it to protect it after you finish polishing it.

    Re: Rusty stainless steel handrail

    I should probably ask how much grinding you actually did in that area. Wonder if you overheated the stainless....

    Though you probably ground in some steel bits. It doesnt look that bad, I've used orbital wax or polishing compound on a buffer and gotten that stuff out. Just depends on how deep. Once its all gone and a mirror finish, you can use a new pad and try to make it look like the same finish as the other sections.

    Re: Rusty stainless steel handrail

    Any one ever try rubbing compound? curious if it removes deeply enough. I used some intended for auto body paint work on a polished stainless sink to remove water stains and minor scratches, it worked amazingly well once I developed a good technique. It's safe, easy, not messy, and cheap, but I don't know if it's abrasive enough to get the iron contaminants out.

    Re: Rusty stainless steel handrail

    Yes. I have, it will work, but the compound has to be abrasive enough. For ground in iron like this, its probably good to start no higher than 600- A DA polisher will be your friend here.

    I have use rubbing compound on stainless steel barstool parts. Easy to end up with a burnt mess if your grit is not agressive enough to get you where you desire. Time consuming.

    Don't know if you can remove the handrail and have it passivated, but that is what I would try to do. Here is a description.

    Re: Rusty stainless steel handrail

    Ya I used I regular steel wire wheel without realizing it. I got most of the rust out with acetone and scotch brite pad then a stainless steel wire wheel. It's 90% gone so I'll repeat the process and see how much I can get out.
