Oh yeah... Don't put your classic old oil jugs in for a clean, or you'll end up with a pile of component parts, it eats solder away

Ach sure there never was a better time to practice the fine art of soldering then so.......Oh yeah... Don't put your classic old oil jugs in for a clean, or you'll end up with a pile of component parts, it eats solder away
think the food grade disinfectant we use for grain trailers etc. is citric acid based, does this mean the trailers are about to dissolve before our very eyesIm told a citric acid dip does symular
I couldn't source powdered citric acid

Personally I would stay clear of the stuff. Nasty stuff if you get it on your skin. One of the lads at work nearly lost him leg when he accidentally spilled some onto his ankle and didn't realise it was slowly burning away at his ankle. Spent 3 months off work and nearly a month in hospital. If you do get it on your skin need to get it washed off straight away followed by another 30mins under the tap.Today in my shed... I have been making a dip tank for cleaning off rust, paint, grease and dirt from bits of machines.It's just an old oil tank with the top hacked off, the drain holes blocked off, the bracing inside removed and a rib fitted round to stop it bellying out. Nothing special...
This is a sewage pump that I had to repair.The pump sat in a bucket of caustic soda/water mix for a few days, taken out and rinsed off, dried and then given a light wire brush, 10 seconds worth.
It eats grease, oil, paint, rust and dirt, skin and eyes, so you need to wear goggles and gloves and waterproofs and keep kids and animals well away. It doesn't touch iron based metal, but eats copper based alloys. Aluminium is not to go in at all, it dissolves quickly and it releases hydrogen gas which could go with a bang.
I've only started using it, played a little with the caustic/water ratio and heating it, but I think it's great stuff (again, treating it with respect)
Has anyone else used it?
Got to watch what you're doing. Full covering of waterproofing and gauntlets (put on before the jacket) and nitrile gloves or marigolds underneath for when there's pin holes in the gauntlets and a full face mask with the hood up on the jacket and you're ok.Personally I would stay clear of the stuff.

You can throw another bag in and keep the ph high. (spilling it in gently and slowly of course. Water first then caustic) there's a light film of gunge on the surface now but it's still working fine. I scrape off the big lumps of grease and dirt before I put the bits in, like the grease in wheel hubs so it doesn't build up too quickly.Been reading this amd it seems a good job.
How long does a tankful last? Till its contaminated with paint etc?
Then how do you dispose of the caustic soda mix when done? Cant chuck stuff like that down the drain surely??
Interesting as always Davie.
