Will this clean Car Window Glass?

Method makes a glass cleaner. I would use that instead.

Does this cleaner work well on soap scum in the bathtub?

Method Tub and Tile Bathroom is the one you want, not the All Purpose. Method is the brand name, it has developed many types of cleaners.

Is this safe around pets?

I have actually used this product to clean some pet messes (which by the way works great). My cats have never gotten sick or anything from being around it.

I am wanting to use this as floor cleaner on our laminate & terrazzo. Any good reasons why I shouldn't?

They have a hard floor cleaner and one for wood as well also your local target sells this line. most 28oz bottles are $2.99 -$3.99 the big refill bottle is only $5.99 I’ve noticed some of the prices here are doubled if not tripled love Amazon but this product definitely cheaper in store
