Worked Wonders

Have had problems with black mould in the grout between the tiles in the shower / bathroom for a while now, had tried various things, and thought I would have to scrape the old grout out and re-grout it, but thankfully Shower Doctor sent me an e-mail about this product, so sent for some as a last resort to try, thankfully it worked, had to use a brass brush to get the deep stuff out, but has saved me a hell of a lot of work.
