We recently moved into a new house. There is a really nice entrance way that would suit a little sitting area, but the old tiles need some love. See pictures. I think most of the marks are where the previous owner had plant pots. I’ve tried pressure washing with no luck.
Hello @FizzyMack
Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about cleaning your tiles.
It appears to be very heavy lime deposits on the surface of the tile. I propose testing https://www.bunnings.com.au/clr-750ml-ready-to-use-calcium-lime-rust-remover_p0356353 . I recommend testing it on a small spot first in combination with a https://www.bunnings.com.au/sabco-professional-green-heavy-duty-utility-pad_p0065292 . Should it prove effective, you can then commit the entire floor area. If you are after a stronger mix, you can purchase the undiluted version and mix it to your preferred strength.
Please remember to wear personal protection such as rubber gloves and goggles when using the spray.
If you have any other questions we can help with, please let us know.
