It is highly alkaline in nature and on reaction with metals including Aluminium it releases hydrogen gas and the reaction is highly exothermic. So, when Aluminium which is an amphoteric metal reacts with caustic soda it will form sodium aluminate and hydrogen gas is evolved as a result.
“Our experience is that you can safely clean aluminum in 500° F, but beyond that, you’re going to soften or anneal it,” He also acknowledged that the time factor to heat clean aluminum is seen by some as a problem. “Thermal cleaning, if you do it properly, isn’t really quick.
Although there are some interesting new methods being tried – bio-remediation comes to mind – the basic technology that the great majority of rebuilders use to clean parts, which are increasingly aluminum, still centers around heating, washing and blasting. Shops we talked to are all over the map about which combination of these three they use.
“Ten years ago, when there wasn’t that much aluminum, people were scared,” said Mike Wigert, sales manager of spraywasher manufacturer LS Industries. “They didn’t know how to regulate their ovens, they didn’t know which chemicals to use, and they were tarnishing their aluminum parts, and probably ended up hand cleaning a lot of them,” he said.
