Try soaking one tile with white vinegar overnight ( place rag over it to keep it wet) , may be a build up of limescale .
The OP rushed back to say thanks.
I laid my indian sandstone few years ago then couple months later i sealed it now it is very white powdery ive tried powerwashing it to get the sealer off.Any good liquid products to remove sealer?any help and advice will be great cheers
There are several liquid products designed to remove sealers from stone surfaces. Look for a stone sealer remover or a heavy-duty degreaser that’s safe for use on natural stone. Brands like Aqua Mix or StoneTech offer products specifically for this purpose.

That white, powdery finish usually happens when the sealer has broken down or trapped efflorescence underneath the surface. You could try a dedicated solvent-based sealer remover (often labeled for “stone sealer strip”), and follow up with a light acid wash designed for sandstone, but test a small area first since it can be sensitive.
