Is the spray as strong as the Bar Keepers Friend powder?

It uses the same oxalic acid approach in a ready-to-use liquid, so it handles rust and mineral stains well. The powder is stronger for heavy buildup and lets you mix a thicker paste.

Can I use it on aluminum?

It is listed for aluminum, but the acid can dull or etch bare aluminum if left on. Wipe it off quickly and rinse.

How do I use it on a shower door?

Spray the foam on the glass, let it sit a few minutes, then scrub and rinse. The upside-down spray works overhead.

Does it remove rust stains from a toilet bowl?

Yes, that is one of its main uses. Spray, let it dwell, scrub and flush.

Is it safe on marble or natural stone?

No. Acidic cleaners etch calcium-based stone such as marble and travertine. Keep it to stainless, ceramic, porcelain and glass.
