Invest? Is it expensive?

I see it's an aerosol type. I never used that before.


I'm using this, Steel Glo, in powder form. Bought it a few years ago, at RM17.90 only.

So far I only used it to clean some stainless steel cookware and kitchen sinks.

Planning to scrub some door handles and door knobs one day.
