Actually, I found ‘SuperClean’ at Menard’s when first looking for ‘Purple Power’! Assumed they were the same.
The SuperClean worked great. When I finally found Purple Power I was disappointed in the results. Reading the labels, SuperClean has sodium hydroxide (lye), which eats the grease. So, in ‘Philbert’s Chain Challenge’ thread I went down a rabbit hole trying pure lye, making my own from wood ash (like the pioneers), and talking to a technical rep at Zep chemicals, etc.
The Zep guy convinced me that a good, commercial degreaser cleans up and carries away other types of dirt too.
So, color aside, look for sodium hydroxide on the label or SDS. I have also seen it on some Zep (Home Depot) and other brands.
Pure lye is available in some plumbing aisles as drain cleaner, and food grade lye (!!!) is available on line for making soap and some food preservation techniques (e.g. lutefisk). Use with care.
On plastics I often try citrus based cleaners first. Purple Power might be a better choice for some other applications.
