MB-3 Soap & Mineral Deposit Remover is specifically designed to safely dissolve soap and mineral deposits from natural stone, tile, glass and fiberglass.

It does effortlessly what can't be done even by hard scrubbing with ordinary cleaners and abrasives. MB-3 Soap & Mineral Deposit Remover is highly effective and safe on most natural marble glossy surfaces. Be certain to test product on a spare tile or inconspicuous area for extra caution before use.

Liberally apply with a sponge and allow to stand, without letting the solution dry, until soap scum begins to break up. Scrub slightly with a scrub brush or plastic scouring pad. Rinse thoroughly. Repeat process if necessary. Drying is not required.

Frequently Asked Questions About Our Scum and Mineral Deposit Remover 

MB-3 Soap & Mineral Deposit Remover is a supreme surface scum and mineral deposit remover suitable for a wide range of surfaces. If you're wondering whether this product would be suitable for your purpose, you can learn more in the Q&A section below. 

What causes the buildup of scum and mineral deposits?

Bar soap, which reacts with minerals in tap water, is a major cause of soap scum. These minerals interact with the bath soap to create a film that adheres to various surfaces. Moreover, tap water high in minerals, such as calcium, magnesium, or silica, can also create "water spots" in the absence of soap and other products that detract from the beauty of the surface.

How often do I need to use MB-3 Soap & Mineral Deposit Remover?

This is not a daily stone cleaner, so we suggest using it every few weeks or once a month to remove mineral deposits and soap scum.

Which natural stone surfaces can I use this mineral deposit remover on?

As long as this product is used as directed, you can use it on natural stone surfaces, such as granite, quartz, and marble. It also works well on tile, glass, fiberglass, & more. As always, we recommend testing it on an inconspicuous area first.

Is this product suitable for composite granite sinks?

Yes. You can use this scum and mineral deposit remover to clean your composite sinks. Unlike other composite granite sink cleaners, MB-3 Soap Scum and Mineral Deposit Remover does not require hard scrubbing, so you can clean your composite sink effectively without much effort.
