ratios of tsp or washing soda

I'm planning on building a 55 gallon electrolis tank. Probably will not be full as it is on its side. How much of the ingredients do i need to add?

Just a plastic barrel that had a couple of cracks close together and needed a use.

Thanks and Happy Thanksgiving.

I just read the other topic on the 60 gallon one. Is there instructions on the tsp container? I don't have any yet and hope i can find some. I've read where you don't get the flash rust with it.

Where do you get your tsp?
 
2 Busy:

Why sideways :?: :?: :?:

Check out Rudi's Electrolysis Tank. This is pretty useful and handles almost ALL of the Cub in pieces.. sometimes you need to do one end then flip over for the second end... but there is a solution for that problem.. just not with a 55 US gal tank..

But if you do go the horizontal version.. leave one of the bungs -- the one with the coarse thread for the outlet..it will accomodate a standard PVC fitting. And you can use a 1Lb box of TSP or the TSP Phosphate Free boxes..

Simple recipe.
55 US Gals = 2lbs of TSP
27.5US Gals - 1lb of TSP

Take pics and post em please :!: :idea: :arrow: :D :!: 8) 8)
 
Rudi, I had to lay it down because it had a couple of cracks in the side that would of leaked. I just cut an oval taking the cracks out. I can install a drain in one of the openings on the top. It had shower cleaner in it at one time. It has a closed top with 2 threaded openings. it was useless as a upright barrel with the cracks.
 
I would take some picstures if someone would donate a camera :lol:

I couldn't use the coarse threaded one as the cracks were on that side. I still think i can put a tap in the other cap and seal it with some seal all.

Where can i buy the tsp? online?
 
look in home depot / lowes in the paint dept. TSP is used as a cleaner for removing mold from siding, and is commonly available.

i switched my tank from washing soda to TSP recently. i noticed a few differences.

1. TSP solution draws more current than washing soda did.

2. flash rust is an issue with TSP, washing soda left a black residue that was easier to sandblast off.

i was thinking of adding some washing soda to the mix...perhaps get the best of both worlds?

I have found real TSP (at well as substitue) at Lowe's. All my local Home Depot has is the substitute. Paint stores also carry it, but for me it has been cheaper at Lowe's.

I have had the black residue after using TSP. I think, to some extent, you get that when working on rustier pieces.

I don't see any down side to having both TSP and washing soda in the same mix. Would be interested in hearing your observations after trying it. Don't think I would try adding ammonia though. :x
 
I have always used baking soda in my electrolysis tank as it is readily available at our local grocery store. I am considering switching to TSP. I have read in earlier posts that there is very little or no rust if TSP is used but a tendency for flash rust is mentioned as a problem in this thread. My reason for changing to TSP is to reduce rust formation. I would be interested in feedback on rust formation (or lack of it) from several forum members who have used TSP. Thanks, Dan
 
Dan:

Check with Cecil, Larry, Peter and a bunch of others.. Gord Trail and I use TSP and have yet to have flash rust or any rust on an umprimed part. In fact the parts we did in the tank before my heart surgery.. we just painted last month.. after 2 years of sitting in my shop unprimed -- NO RUST period :!: :idea: :shock: :lol: :lol: :lol:
 
Rudi: Almost sounds too good to be true but those are the results I want. Any idea on how TSP blocks the process of rust formation? Dan
 
Nope, it just does... that is why I have been recommending TSP only for the last couple of years. The fact that I can't find Washing Soda easily, doesn't realy enter into the equation. Baking Soda I only use for settling my upset stomach... :!: :shock: :wink: :lol:
 
2 Busy, I haven't had the same luck with TSB in terms of flash rust. I have just finished the battery box for an Allis CA and it rusts up pretty fast. I'm starting to wonder if the amount of TSP per gallon is the key to whether it flash rusts or not. The smaller bucket I use is 20 gallons with one pound of TSP. Just as information, the process doesn't work as well with things like battery boxes as the process seems to work in straight lines so the inside of the box doesn't get as much cleaning. The black stuff that's left seems to brush off OK. I assume its some sort of chemical residue. It sure removes layers of old paint in pretty good fashion. What are folks doing with the liquid after it gets gunked up. Someone said TSP isn't good to get into the ground water.
 
Mike:

When I drain my tank, I just drain it out onto my lawn. It is a great fertilizer. Would I dump it in my well :?: No :!: Would I dump it in my brook or pond :?: No :!: But, for it to adversely affect ground water, would require a large concentration. The TSP would be naturally filtered as the water perks down through the various strata as it heads toward the water table. Once it reaches the water table, I would assume.. not being a biologist or whatever, that it would basically just soften the water a bit.. TSP is similar to water softeners in composition.

TSP is also nothing but salts and some phosphate. It is all naturally occuring. I know this from my prospecting.... where the problem occurs is in man's penchant for overdoing everything and overwhelming mother nature.. that is what caused the problems with the huge algae blooms in the Great Lakes in the 60's -- mostly stupidity.. too much phosphate in the waste water stream being dumped into the Great Lakes..

I am not sure where the line of sight plays.. I don't think it is all that critical... you can do the inside of your tank or almost anyother part quite nicely, but it may take a bit longer..

The black stuff is residue and it cleans off easily. As for the rusting part.. I use a 45 Imp gallon barrel and 1 kg or 2.2 lbs of TSP.. no flash rust.. why don't know, concentration -- probably may have something to do with it..
 
I read somewhere where you could neutrilize it with baking soda. Seen it when i did a search for tsp.
 
I have a snow plow/grader blade which I plan to sell. Can't decide whether to clean it up or sell as is. I will give TSP a try if I clean it up before listing it. Dan
 
I believe it is the phosphate in the TSP that inhibits the formation of rust. Take a look at the Picklex website. I think the chemical processes are probably very similar.

Ironically, it is also the phosphate that presents any potential pollution issues. I believe they would be more related to surface water sources than sub-surface sources, though.
 
I suppose the relative humidity of your location could also have something to do with whether parts flash rust or not. I would think that things would rust quicker in the higher humidity levels of the southeast than in the normally lower levels of the the southwest or the north.
 
Well I am not so sure about it being the Tri-Sodium PHOSPHATE that does the trick.

When we were at Cecil's, I was astounded that the PHOSPHATE FREE version that was available in New York worked like the real stuff.. I was impressed with Cecil's comments on the flash rusting, as it coincided with my experiences... but when I found out he used PHOSPHATE FREE TSP.. I was incredulous..

So, I am beginning to think that maybe it is the concentration of the solution.. that makes the difference..

Cecil was able to get the Savogran version and I am a DAP believer.. much like Country and KROIL :roll: :shock: :wink: :lol: :lol: :lol:
