What should I do if a white haze remains after grouting?

It's probably dried grout residue; clean it as soon as possible with a grout cleaner suited to the type of grout.

Can polished marble be cleaned with an acid construction detergent?

It's not recommended on acid-sensitive polished limestone; it's better to use a cleaner formulated to be safe on those finishes.

Final Construction Cleanup and Floor Maintenance: A Guide to Fila Detergents

Q: Can I use any acid for final construction cleaning?

It's not recommended, strong unbuffered acids can damage the material. A product with buffered acid strips buildup without those risks.

Quick answer: after installing flooring or tiling, there's always a cement haze, grout residue, or salt efflorescence left behind. It's removed with a final construction cleaning detergent based on buffered acid, which strips away buildup without damaging the material or releasing toxic fumes. This is an essential step before applying any protector or wax, because those products don't work well on a dirty surface.

Organic stains and grease on porcelain stoneware	PS87 PRO	Also strips all types of wax

Specific grout and silicone cleaning

Fuganet: deep cleaning of cement grout in ceramic, porcelain stoneware, and mosaic tile.
Instant Remover: removes fresh grout mortar residue before it dries and leaves a "cloudy haze."
EPOXY PRO: the same idea as Instant Remover, but for fresh epoxy grout.
Silicone Refiner: used while applying silicone, for a clean, bubble-free finish.

Recommended order for a new installation

Final construction cleaning with Deterdek Pro (or PHZERO if there's intense efflorescence).
Specific grout cleaning with Fuganet if a haze remains in the grout lines.
Applying the protector or water repellent suited to the material.
Wax or final finish if the flooring requires it.
Daily maintenance with a neutral detergent like Roboshine or Cleaner Pro.
