WD40? Dawn? What other grease cleaner? Thanx.
You guys kill me with your laborious work! Spray on.....Hose off!!

Not true. Hot-rodders have been using it on their aluminum engines and manifolds for almost a century.Not good stuff to use on aluminum. Very caustic

It has eucalyptus!
It contains less than 0.1% caustic soda (sodium hydroxide) and the contents have a pH of 8.3. Not terrible.
Look up sodium carbonate.
A BIG difference between a thick engine block or manifold and thin aircraft aluminum. And aircraft have seams that this stuff can get trapped and eat the structure.'
I can't order water at restaurants in town. Chlorine content of pool water. So glad I'm on a well.I’m pointing to pH and the “low-ish” relative concentrations of these corrosive compounds. It’s not like dumping soda ash or caustic on bare aluminum.
Would you spray anything greater or less than pH 7.0 on your plane? What’s the pH range of potable water in the US? I think some would be surprised to find the pH of our water approaching that of some household cleaning products.
Don’t get me wrong, I don’t use this stuff (I use WD-40) but it’s not as horrendous as using 409 or Super Clean. If one wanted to check, just look in the back interior of the plane at the bare aluminum seams to see if years of using this stuff seeping into the seams is bad. I don’t know. I’m just pointing out the chemistry.
