Stain of rust on railway

Post by gilles13006 » September 13th, 2021, 12:18 pm

Hi,

I own my brand new concept2 since March, and today i noticed some very little rust stains on railway.

I clean my railway with classic cleaning wipes (which contain Chloride and ethanol.

Do i have to stop right now to use it or is it due to another thing ? I keep my rowerg indoor all the time.

Best regards
Gilles

Use a simple household cleaner like Windex. The rail is stainless steel, if you're seeing rust that may be from your excessive use of industrial cleaners on the top of the monorail getting under the stainless steel track.

The rust marks may be from some form of contamination from the track being in contact with iron/steel. See information in link below:

https://bssa.org.uk/bssa_articles/iron- ... ess-steel/

In general, Chlorides are not good for stainless steel. I use a window cleaner spray for mine but in the past have used a PTFE dry spray.
There is no need to stop using the rower, just worth having a think about where the iron contamination may have come from?
The tracks are listed as spare parts and so can be replaced. £20 if you are in the UK.

Hope this helps.

Agree with above, don't use chlorides on metal. Use a silver metal polish like autosol to remove the rust spots.

The surface of the rail is made of stainless steel. Most stainless steels are not rapidly attacked by chlorides. That is why it is often used for food utensils. Sweat is water + chloride salts, mostly sodium + lactic acid + urea. C2 would have done a bad job if they had chosen a stainless steel that stains from sweat drops. It would be interesting if you post a picture of the rust stains.

Direct from the C2 mother-ship wrote: Daily

Wipe the monorail with a cloth or non-abrasive scouring pad after use. You can use soap and water or any glass cleaner. Do not use mineral acids, bleach, or coarse abrasives.
(Emphasis added)

Avoid the chlorine solutions. There is a cleaner called “Bartenders Friend” that is great for removing spots from stainless. It is a very mild cleaner, made just for stainless. Also works great on pans and stainless sinks… bonus points :D For regular cleaning, Windex works very well.

Probably a misunderstanding about names of chemicals :
- kitchen salt = sodium chloride ; component of sweat drops ; harmless to stainless steel .
- bleach = sodium hypochlorite ; in solution unstable and easily decomposes, liberating chlorine, a smelly gas ; corrosive to stainless steel.

Thank you very much for all your answers.

Wipes i use are industrial disinfectant wipes (like those used for covid prevention). Their composition are similar to other brands like

Here are some pictures, you can see a little brown stain on the side of the rail. There are 2 of these on the rail.

Should i stop right now to use them?

(sorry for the french packaging)

The main suspect in the composition is didecyldimethylammonium chloride. I wouldn't expect it to be corrosive, but who knows for sure? Why would you use such a strong antiseptic to clean the rail of rowing erg?
I just use a sheet of paper towel to wipe the black dirt and to dry. Toilet paper would do as well.

If you read the safety data sheet, I would indeed immediately stop using them. Skin burns, eye damage, brrr...
May be corrosive to metals, indeed.
For professional use only!

Thanks for answer.

After some investigation i found this paper. My conclusions by reading it is that stainless steel is mostly protected against rust, but there is a little bit appearing.

So i will not play with the devil and stop right now to use it.

As a buddy of mine at work says, "Don't forget, it's called "stain LESS," not "never, ever, ever stain."

Oil, chlorides and organic acids can corrode type 304 steel. All these could be in sweat, so a clean dry rail is what's needed. Water and paper are good enough, since there is nothing difficult to remove.
