CLR for hard water removal?

So I take it 550 is a last resort, right? I should try saferestore or some other milder product first?
For me, 550 is a last resort. It is a risk to my health and the customer’s property.

If I am working the tin side, should I just go straight to the cerium oxide and skip the 550?
If you are working on the tin side, 550 will instantly ruin the glass.

Could I avoid using 550 altogether and just use cerium oxide on the tough stuff? I would rather avoid having to mess with harsh chemicals, but I am comfortable with it if necessary.
Sure, but cerium oxide and mechanical polishers/scratch removal systems have their own pros and cons.

Thanks for the advise, I will do some research on both products.
