How to clean concrete sleepers?

[OtisS]

Hi! What are recommendations for cleaning concrete sleepers please? I have tried water, dishwashing liquid and bicarb soda- removed dirt but it didn’t remove the stains. I don’t want to pressure wash as I think the dirt from the higher block at the back will come through - and I’ve heard not to do that anyway.  What could you suggest I do - any products that would help?  Thank you.

Hello @OtisS 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about cleaning concrete sleepers.

I suggest using 30 Seconds 5L Outdoor Cleaner Concentrate. It removes algae, moss, mould and mildew from exterior surfaces. It's safe to use around garden, restores outdoor surfaces to looking like new again. I suggest using Oates Compact Deck Scrub Brush to scrub the surface of the sleepers. To maintain and prevent further moss, mould and mildew, I recommend suing 30 Seconds 5L Spray And Walk Away Concentrate.

Please remember to use personal protection such as gloves, goggles and mask when cleaning the sleepers.

If you need further assistance, please let us know.
