Stainless Steel plus Saltwater Equals Rust

I’m a Reef Gadget user. If you’re not familiar, this is a little piece of plastic that holds a razor blade, and it is glued to your Mag Float. It makes cleaning your glass a snap.

I couldn’t live without it. It is actually my second most favorite purchase I’ve made for my tank. (The Glass-Holes overflow is number one.)


When you first buy a Reef Gadget, it comes with both a plastic razor and a stainless steel razor.

I did not like the plastic razor because it still had problems scraping off some of the things on the glass….such as coralline algae. So I now only use a stainless steel blade. The problem, even with taking it out after each and every use and rinsing with fresh water, is that it rusts up within no time.

I actually purchased a hundred-pack of blades, and I’m quickly going through this box. They are termed stainless steel, but it must be a low grade because they begin to rust after the first use.


At a recent club meeting someone (whom I can’t remember) mentioned that he coats his blades with a thin coat of vegetable oil. This didn’t sit well with me…..I felt you would still get a small oil slick within the tank, and even a small amount of oil would certainly impact bubble formation in the skimmer.


When Sandy hit, having an electric stove/oven, we ended up pulling out all our cast iron pots and pans to cook on the outdoor grill. This reminded me of the conditioning you need to do to cast iron before you us it. So I thought I’d try the same process on some blades to see if I could polymerize the oil to the blade and protect it from saltwater. I oil coated three blades with Canola oil and put them in the oven for an hour at 400 degrees. When I pulled them out I noticed that the one blade that wasn’t overlapped was ok on that side, but the back side of each blade and anywhere the blades overlapped, the oil didn’t “bake” onto the blade.

The even bigger problem was that I now had to take some flak from my wife for screwing up one of the ramekins. No crème brûlée for me tonight! I’m now trying to get that burnt oil off the ramekin before she sees it. Does anyone know how to do that?


Anyway, since the ramekin method didn’t work…and by the way, the spacing on the oven grate is too large to simply lay the blades in the oven…..I had to come up with another way to “cook” the blades without them touching anything. So I took these three blades and one new one, coated them with oil, and now hung them through the holes they have, on a piece of wire that was then suspended in the oven. Again, cooked them for an hour, but now at 350.

I’ll update this thread when I see any results …. positive or negative.

I bought a 100 pack also. The gadget is great. I leave mine in all the time and they sure do rust. I had one rust and leave brown on the glass where it was parked. I saw no ill effects.

I wish Rich was still making them too, my son broke mine last night. Fortunately I know I bought a few extra, but finding them is a different story.

Ed, I saw that coralvue is distributor for the flip mag, do you know if this is the same one that has been on the market? The reviews I came across weren't the best, but I don't know if it is the same product. NOTHING will beat a reef gadget though!

Update:

Correction – My wife was actually cooking something when I did the ramekin baking of the blades and see actually turned the oven up to 450. I didn’t know that until now.

Just pulled the wire-hanging group out of the oven, and 350 wasn’t hot enough for Canola oil. I just have hot oily razor blades. I’m going to do this again, but at 400 or higher, and I’m going to wait until we cook something else so I don’t waste the electricity just for a few razor blades.

Matt, as far as a torch is concerned, I don’t know. You only want to polymerize the oil (slightly char it), not burn it to a crisp. If you lightly and carefully use the torch, it might work. Again, I’m using this method because this is how you condition cast iron pots and pans. If done correctly, it actually makes the cast iron “non-stick” like.

And finally, it is a shame that you can no longer find these. I just double checked TB Aquatics website because I know he was a distributor for Reef Gadgets and was hoping he still had them in inventory. But no luck!
 
the smoke point for Canola Oil is between 375-450. I use it if I am in a pnich on Thanksgiving and don't have enough Peanut Oil to deep fry the turkey.
 
Stick a magnet to the blades, if they are truly stainless steel the blades will not stick to the magnet. A lot of junk is sold as stainless steel these days, even BBQ grilles and they are no where near being stainless. I leave my boat in saltwater with 2 stainless steel props and they don't rust at all, they are actually true stainless.

I will agree that there are many grades of stainless.....but as far as your propeller, you're most likely running a zinc anode. That's were your oxidation is going to happen.....think of it as having a greater potential to oxidize.

Yes there is zinc involved, the stainless props pit more than rust.

I use this: http://www.flippercleaner.com/
Have had it in the tank for 6 months now with no rust on the blade...

Wow, that looks like a great product. I might get one of those.

I've been using the Kent Pro Scraper with their stainless steel blades and they work pretty well. I haven't seen any rusting on those blades, but the ends tend to bend occasionally, which means they need replacing. I sometimes use one of the spare blades without the handle to clean tight areas and along the top trim.

George’s post above reminded me about this little experiment. About a week ago I finally got around to cooking these blades. They received a light coat of Canola oil and then suspended in a 425 degree oven for one hour. After cooling, I went to wipe off any excess oil, and they were totally dry. All the oil had been baked onto the blades.

I’ve been using the one all the way to the left for about a week, and although early to make a final decision, it looks promising. The water beads on the blade, similar to a freshly waxed car. After a week, no visible signs of rusting….but again, it’s still early.

George, without question, this coating is protecting the blades. Going on three weeks and not a spot of rust. Actually as I type, I have four blades cooking at 450 degrees while I’m cooking up some spiced sweet potato fries.


You have nothing to lose.....cook your blades with a little oil! Dance
