Anybody know why my AR handguard would turn white?

I have an MPA 30 with an AR handguard on the 10" barrel. I cleaned the gun after my last trip to the range. I used Break Free cleaner and lube along with the Break Free blaster. Some got on the guard. Anybody had their handguard finish turn chalky white?

Yes

It's the cleaner. I used it to clean my Ruger target 22 Sunday and it turned the Plastic white. I'm thinking using it on plastic is not a good idea.

Usually caused by one of those strong degreasers like carb/brake cleaner.

Could be your BF Blaster.

I seem to recall that re-aplying regular BF tot he plastic & letting it sit helped de-white it.

I am always careful not to let plastic/polymer or wood come into contact with strong degreasers & solvents.

What is the composition of Break Free Blaster? Anything like carb cleaner?

In the Marines, just like jfruser mentioned, we were specifically told to apply CLP (the BreakFree oil) to our buttstocks to counter fading/whitening.

If those are the only two products that you used to clean, I'd say it has to be the BFB. Try rubbing some CLP into the whitened plastic with a rag and see if it glosses back up.
