Scouring Stick

As assumed, this product will remove some grout between tiles. Likely it will not remove a lot of grout, yet due to its abrasive nature, some will be dislodged. Depending upon the soil embedded in the grout, removing some might be beneficial. Yet if keeping all gout intact, I recommend a product like Tilex or ZEP, Mold Stain and Mildew Stain Remover, both sold by Home Depot. Both will whiten grout and destroy mold and mildew. Again, some kitchen stains can only be removed or reduced as they soak into unsealed grout by removing the top layers of the grout. Some stains, like permanent dyes, might not come out with a surface cleaner only.

The pumice stone is not that expensive to try and it can be used on other hard scratch resistance surfaces in the home if scratching the ceramic surface. However, if using this stone on a ceramic cooktop, I would first try it in an inconspicuous area as it may scratch an otherwise glossy surface. Ceramic and enamel surfaces are softer than porcelain finishes where this stone is typically used. A product I really like is Frigidaire, 12 Oz. Ready Clean Glass and Ceramic Cleaner, sold by Home Depot, Internet #306741999 Model # 5304508690. It is a chemical cleaner that dissolves debris rather than a mechanical abrasive that scrapes off debris. However, it works best when used regularly and heavy caked or burned on debris may be difficult to remove.

Sometimes when searching for items on Home Depot’s Web Site for in store items or online items, it is best to use a search engine rather than the search feature on Home Depot’s web site. I first leaned this trick when a Home Depot employee helped me to find an item in the store by using a search engine outside Home Depot, like Yahoo or Goggle. The search feature on Home Depot’s own web site tends to be very specific based on how the manufacturer refers to the item rather than common names or descriptions.

No, please do not use on glass shower doors. Glass is too soft a material not to scratched by the pumice stone. Truly, if mineral deposits are fouling shower glass doors, Home Depot sells a product called AMAZ, Water Stain Removed. It requires a bit of elbow grease on the first application, yet with regular use, shower doors can and will look showroom new. I find the best use of these pumice stones is on hard surfaces like porcelain. There is porcelain on steel and there is porcelain on glazed ceramics done at very high temperatures. Porcelain is one of the hardest materials pumice stone will not scratch. Enamel and glass surfaces tend to be too soft for pumice, which is actually volcanic glass its self.

6x1.25x.75 inches. You should be able to use it on any of the porcelain surfaces

Yes, this scouring stick can be used on concrete pools.

NO! It will scratch fiberglass

You probably already took care of this by now, there’s a product that’s in a container like Ajax or Comet called Barkeepers Friend which works excellent to remove rust I would get a little scrub brush and bar keepers friend and a little water and I bet it would take it would take care of it.

It will not damage your dishwasher. It will work nicely.

Yes, this will work nicely to remove the dark marks.
