How to clean Terracotta porch tiles?

We have terracotta tiles on our upstairs verandah and downstairs porch. I suspect they are unsealed. The concrete/grout in between is quite dirty and so are some of the tiles. Should I just pressure wash them or is there a product or other method I should be considering?
Thanks in advance for your advice.

Hello @CatherineA

Welcome to the Bunnings Workshop community. It's sensational to have you join us and thanks for sharing your question about your terracotta porch tiles.

Aside from using your pressure washer, I also suggest having a look at 30 Seconds 5L Outdoor Cleaner Concentrate. I recommend using the DTA Long Handled Grout Scrubbing Brush to give the grout surface a good clean.

If you need further assistance, please let us know.
