anglia4 Posted October 20 Share Posted October 20 So, brought an ultrasonic cleaner, filled it with simple green and water. cleaned a carb. then it did this… Any idea what I’ve done wrong? have i stripped the anodising off? is there any saving it? 2 Quote Link to comment Share on other sites More sharing options...
tortron Posted October 20 Share Posted October 20 That's new to me and I have cleaned similar with simple green before What colour simple green did you use? I use the purple one Did you dilute it? How long? I never looked into what's in either, bit I remember reading stuff like this Il tell you a secret for next time Cheap dishwashing liquid like dawn works just fine. Jar of solvent for the baked on stuff 1 Quote Link to comment Share on other sites More sharing options...
anglia4 Posted October 20 Author Share Posted October 20 Aha. Yeah I used the green stuff at a fairly grunty mix Quote Link to comment Share on other sites More sharing options...
anglia4 Posted October 20 Author Share Posted October 20 I think it went in for 2x 5min sessions at 40deg. i might run it again with just water, and see what happens. Quote Link to comment Share on other sites More sharing options...
mjrstar Posted October 20 Share Posted October 20 Looks like caustic attack. You might get away with a quick blast in the cleaner, then a thorough rinse /neutralize. Quote Link to comment Share on other sites More sharing options...
tortron Posted October 20 Share Posted October 20 Yeah probably too strong for the green, it's got citric acid and washing soda etc in it. Quote Link to comment Share on other sites More sharing options...
tortron Posted October 20 Share Posted October 20 Oh, as for my ultrasonic fk up I transported a chemical jar of frys reagent in my cleaner when we moved It leaked Frys reagent, it turns out, dissolves stainless steel, so it now looks like a colander If I can salvage the board etc I will attach it to a stock pot lol, but I'm not hopeful 4 Quote Link to comment Share on other sites More sharing options...
mlracing.co.nz Posted October 20 Share Posted October 20 Did you wash and scrub it down with normal water straight after? I hear sometimes that can happen. Quote Link to comment Share on other sites More sharing options...
anglia4 Posted October 20 Author Share Posted October 20 I ran it once and it looked a bit odd after a few hours and I thought that might have been from needing the cleaner rinsed off, so ran it again to clean it up, then rinsed it jn a bucket of water and dried it. came back to it a couple of days later and found that… Quote Link to comment Share on other sites More sharing options...
NickJ Posted October 20 Share Posted October 20 How hot was the tank? Ali is best at low temp or it does horrible things, especially with high pH cleaners Quote Link to comment Share on other sites More sharing options...

anglia4 Posted October 21 Author Share Posted October 21 I’ve just run it back through the cleaner for 10mins in plain water and it looks heaps better. fingers crossed it doesn’t blow up in corrosion again tomorrow. 2 Quote Link to comment Share on other sites More sharing options...
Lord Gruntfuttock Posted October 21 Share Posted October 21 Oh interesting. I've done a few carbs in simple green and only ever had one go a little like that. I dilute and rinse off immediately though. Will investigate the SG purple. Didn't even know that was a thing... Quote Link to comment Share on other sites More sharing options...
Carsnz123 Posted October 22 Share Posted October 22 I use mine on carbs a lot and have found that usuing distilled water also helps a lot. I use a solution that RCS sell which is literally called ultrasonic cleaner fluid. For some shit it's not quite as aggressive as I'd like but it works pretty well. Especially when dealing with unobtainable carb parts. 3 Quote Link to comment Share on other sites More sharing options...
Lord Gruntfuttock Posted October 23 Share Posted October 23 Ah maybe cos I'm on tank water it goes ok, had it tested for brewing and it's near as dammit distilled water quality... Quote Link to comment Share on other sites More sharing options...
anglia4 Posted October 23 Author Share Posted October 23 I just did 2 more carbs in it with 4 squirts of dishwashing liquid and its worked OK. 6 mins and then turned the parts over for another 6 minutes and its cleaned up pretty good. Could do better but at least I'm not melting them now. Will explore the Purple stuff or the ultrasonic cleaner fluid as I need to work out a safe way to use it before I go jamming my Holley parts in there. 2 Quote Link to comment Share on other sites More sharing options...
Tiger Tamer Posted October 23 Share Posted October 23 I cleaned a carb in the ultrasonic cleaner I have. The carb is a Holley style carb and the secondary bowl had a brown film coating on it due to it drying out through evaporation I was told. I put the metering block and jets etc in a zip lock bag and sprayed a shit load of CRC carb cleaner into it, so it was in fluid. Put it into the ultrasonic without heat and nothing much happened. Rinsed it out and put warm water and detergent into the bag and placed it back into the ultrasonic and as soon as i turned it on you could see all the film dissolve into the detergent water mixture. 4 Quote Link to comment Share on other sites More sharing options...
