Removal of white blooms and chalky residues

White, mineral-based residues can ruin a tile installation.  They come in various guises – from that chalky white grout haze left after an installation, to white blooms that rise up from a subfloor. As well as compromising appearance, they can also make maintenance really difficult.  So, how can you remove them without damaging a tile or natural stone surface?

Most of these residues can’t be removed with a standard cleaning product.  They need something tougher.  The problem is that acid-based solutions generally needed to remove minerals can’t be used on a lot of tile surfaces.  If you attempt to clean an acid-sensitive material with a traditional acid cleaner, like ‘brick acid’, it will corrode the surface and effectively eat it away.  Hydrochloric-based acids also emit harmful fumes and can damage certain metals, like aluminium trims around a shower enclosure.

A safe and effective solution comes in the form of LTP’s new Cement, Grout & Salt Remover.   This brand new product replaces conventional acid and, when used as instructed, is safe to use on all types of tiles – from porcelain to glazed ceramics – and all natural stone surfaces too, except for those with a polished finish.  A diluted application removes mild mineral residue within 30 minutes, whilst a stronger application and agitation gives instant results.  After treatment, just extract deposits with a sponge and rinse the surface with clean water. Wet vacs can also be used.

Efflorescent and spot fixing

As well as removing cement and grout, LTP’s new Cement, Grout & Salt Remover also disperses rising salt residues caused by efflorescence and spot fixing.

Efflorescence is very common on outdoor surfaces, like bricks and patio pavers.  It creates a powder-like dusting or ‘bloom’ on the surface.  Efflorescence is caused by soluble salts and moisture rising from the ground or subfloor, or migrating through a wall.  When they reach the surface they evaporate and leave a layer of salt deposits behind.

Spot fixing creates a similar issue.   Adhesive is often dabbed onto each corner and the centre of a tile to fix it onto a wall or floor.  This creates a void between the adhesive, the tile and wall/subfloor. Moisture from the adhesive then collects in this void; minerals from the adhesive or concrete sub floor are then activated and they travel through to the tile surface, leaving a tell-tale ring mark or staining effect above each dab of adhesive.

Usually, an acid-based treatment like LTP Grout Stain Remover would be used to remove these marks from acid-resistant stone – but, where the surface is acid-sensitive, LTP Cement, Grout & Salt Remover now offers a safe and very effective solution.
