Cleaning rust from water jackets.

[deuce_roadster]

It is too bad that the Redi-Strip process doesn't seem to be available most places anymore. When one was available near me, I had blocks (and a 34 body) cleaned and there wasn't a speck of rust anywhere inside or out when they were finished. I believe proper disposal of the extremely toxic waste became so expensive it became not feasible to run a franchise. I don't blame the regulations, that stuff just can't get into the environment. The Redi-Strip that was forced out of business here had been dumping waste into a river close to their building to save money.

Agreed, the stuff is noxious. But I have a hard time believing they couldn't tack on $10 per job in "environmental fees" to pay for a neutralizing system. Lucky they weren't sued for what they'd been doing all those years. (Maybe that's why the folded?)

That's another great thing about Evapo-rust. It is not an acid nor an alkali and can be disposed of down the toilet. It is not toxic in any way. For a demonstration of the difference between acid de-rusting (Vinegar) and chelation de-rusting (Evapo-rust) see here: http://www.fordbarn.com/forum/showthread.php?t=123032

Of course, no chemical will remove old casting sand which I think is the main source of the problem cooling flatheads that are otherwise totally free of rust. Manual labor is the only way for that crud.

I'm using a Streamlight LED penlight to look inside the water jacket. These things will put a beam into places a shop light can't touch. I keep it in my pocket whenever I'm in the shop. It is amazing what good light will do for ancient eyes.

There is no casting sand or debris in this block anywhere that is viewable from the holes in the deck. As I said earlier, the block was cleaned from every access with a 3000# 4 GPM pressure washer before going to be dipped.
