oh sorry...I agree there is no way that a soft nylon brush is going to damage the grout. The only way that will happen is if the grout is weak .<br><br><div class="gmail_quote">On Mon, Jun 6, 2011 at 8:14 PM, info @<a target="_top" href="http://surfaceshawaii.com">surfaceshawaii.com</a> <span dir="ltr">&lt;<a target="_top" href="mailto:info@surfaceshawaii.com">info@surfaceshawaii.com</a>&gt;</span> wrote:<br>

<div><br></div><div>I want them to understand that the way we are cleaning is not aggressive enough to damage grout, we are following standard maintenance practices and if you have grout coming out from light maintenance, the problem is most likely improper installation (cuase it was installed last year) or some other factor.</div>
