    How can I remove cement on the edges of patio slabs, the joints have been filled but it has left an unsightly mess along the edges?
    Thanks.

    If they’re natural stone don’t use brick acid

    start with a stiff brush and water, then a metal scraper. if you laid them on a dry sunny day the mortar might not have much strength. you can work you way up to a wire brush (preferably not steel wire as it will shed particles that cause rust stains)
