Marks (now solo) M1100 (mis) adventures!

[Mhanis]

I found a couple of OLD threads on the subject and one of them used WD40 and Scotch Bright pads, however, the images in the thread were no longer showing. That is the method I went with since I had those things handy. Acid sounds scary and I don't want to get involved in black market toilet bowl cleaner! 

I'll roll with this for now. I am really quite surprised how much they cleaned up.

Since money is no object... you ought to send them off and have them ceramic coated!  That's what I want to do with mine...

Better living through chemistry.

Federal authorities intercepted a container load of illicit........ toilet cleaner

[koko64]

I used the WD40/scotchbrite method or scotchbrite then one of the Autosol/Mothers metal polishes with ok but not brilliant results.

[ungeheuer]

Solvol Autosol and a gazillion hours of elbow grease brought my Guzzi headers up all shiny new. 

[ducpainter]

Muriatic acid for the win.

Hours of elbow grease for shiny? Not this kid.

[Charlie98]

Muriatic acid for the win.

Mark... I got lots of Muriatic Acid! 

I'm curious... what % solution to use for something like that?

[ducpainter]

Start at the recommended 10:1 water to acid, and see how it works. You can go stronger if it's too slow, or doesn't work.

Gloves and goggles necessary.

[stopintime]

Apply - wait - rinse - repeat = an hour

Autosol an hour.

[Mhanis]

Using the acid, would I use the scotch bright pads again, or do the pipes get submerged into the acid?

Mark

[ducpainter]

I'd just brush, or spray, it on. Keep them wet until they're clean. I suppose the extra elbow grease couldn't hurt, but you may have scothbrite scratches to polish out.

If you have a container deep enough to submerge them, and enough acid that would work, but you'd have a lot of acid to dispose of.

Mark,

I just dropped 3 cases of acid off at my brother's house over Thanksgiving.  He uses it to clean engine parts on his (salt water) boat... although I'm not sure of the exact application.

Your skwerrel bucket would work for a 10:1 solution, but as ducpainter mentioned, you'd have some acid to dispose of.  I don't know if I'd put it in the pool... because it might have metals in it, and that won't do the plaster any good.  You could also neutralize it with sodium bicarb (baking soda,) which I also have in quantity.  That bucket with 10:1 could be neutralized with 4 scoops of BiCarb... easy peasy.

We'll discuss next time I see you.

How much do we think a dry M1100 engine weighs?
