Removing Limescale staining from a Black Limestone Shower Cubicle in Everdon
Limescale deposits are a big problem in many parts of the UK where hard water is common. To remove it you need to use a strong acidic cleaner however what to do if you have limescale deposits on Limestone? As many may already know, Limestone is an expensive, high-quality stone that like a lot of natural stone is acid sensitive and can be damaged with the application of acid-based products.
Cleaning and Burnishing a Stained Black Limestone Shower Cubicle
As the staining was so severe, I opted to use Tile Doctor Acid Gel to clean the tiles. This is a blend of phosphoric and hydrochloric acids in gel form and is the best product for cleaning vertical services, since water based products just run off and don’t have time to work on the staining.
Working in small areas, I carefully scrubbed the product into the stone and then rinsed it off with plain water. This process was repeated across the whole cubicle, reducing the stains significantly in the process.
Next, I used a handheld polishing machine fitted with 6” diamond encrusted burnishing pads, along with some water for lubrication, to polish and deep clean the stone, removing any stubborn stains remaining on the tiles.
Sealing a Black Limestone Shower Cubicle
I left the cubicle to dry completely overnight. Upon my return the next day, I proceeded to seal the tiles using two coats of Tile Doctor Colour Grow sealer.
This sealer is impregnating, meaning it fils the pores of stone to protect against ingrained dirt and staining. As well as providing stone protection, Colour Grow also enhances the natural colour in the stone – in this case, the deep black shades in the Limestone.
