I was attempting to clean the front bumper/grille from an SMP 1961 Chrysler Imperial using Dawn Platinum Powerwash Spray. Scrubbing with a toothbrush, I discovered that it would completely remove the chrome plating.

But Did it remove the Lacquer undercoat?

Yes, it did. I just stripped the rear bumper of an AMT '58 Plymouth down to its gray styrene. No lacquer undercoat left.

After the owen cleaner, Tamiya lacquer thinner take the undercoat away over nigth. A Wood toothpick does the last whitout scratching the parts.

Edit: I have stripped old Monogram and new Round2 overnight and even a couple of nights without problems but you should probably test with a piece of the sprue to be sure. 

Happiness is taking parts out of the oven cleaner and see that there was no undercoat..

Is the “Tamiya” lacquer thinner weak enough that it won’t melt the styrene like generic LT will?

Update, I put a chromed part from Round2 directly into Tamiya's lacquer thinner and after 18 hours I just had to brush it lightly with a toothbrush and the chrome flakes flew like light snowflakes. Now I will skip the mess with my decanted oven cleaner as long as the Croweparts fit in the thinnerjar.
