Hi!! difficult to see from picture, may I know the results and you are really happy? as in the tainted stains gone?

Can I have their contact and how do they charge?

My tiles also kena by the timber flooring varnish ppl, the workers accidently spilled some of the liquid on my tiles which cannot be get rid of. They also unable to find the tiles to replace as different batches will have different color tone.

Thanks in advance
