Trisodium Phosphate and Auto Paint

[JHZR2]

I like Meguiars #57 for rubber, especially when cleaning is needed to remove bakes on pollen and residue.

But it has 1-5 or some percentage TSP. TSP is an alkaline cleaner/degreaser that is known to remove gloss, at least on gloss and/or lead household paints.

One should always be careful, but the potential always exists, especially on more complex seals and rubber parts, like on a convertible, to get it on the paint.

Automotive paint is obviously not gloss household paint. But TSP could have some effect. Anyone have any firsthand experience?

it may be a moot point in the percentages used. Since it's from the "marine" line, it's not clear if marine paints and coatings are, again, different.

And yes, I get that stuff should be masked off, wiped off, etc. care should be taken. But is there reason for concern?

thanks!

I wouldn't use TSP on a vehicle. If you're trying to clean window seals, or trim get a cheap MicroFIber rag - it's going to turn black and gunky on window seals thus you'll toss it. Put a few drops of white mineral oil from the store on it, and viola....it will pull off dried on wax and most anything while cleaning the seals. They will be a nice satin black when you're done too. If you want to coat or seal them, just go over it again with a clean MF rag and some IPA mix and pull of the residual oils. Works far better than any "wax removers" on the market and is an old-school trick that works.

For at least 25 years, or so, I’ve been
using Meguiar’s M40 (the Automotive
“equivalent” of Marine 57) only on vehicles’
surfaces/components for which it has
been stated to have been formulated for,
and recommended to be used upon...
all the while having absolutely no harm to
ever befall any such vehicles’ surfaces.


Coincidentally, M40 contains the same
1-5% (by volume) of TSP as you listed
for its Marine cousin.

I am pretty sure one of the 3 FK1 Decon system steps was a TSP wash. Aren't most semi-truck presoak washes TSP based.
