Id be more than happy to review the MSDS for the Biowash and make a statement.

I am not familiar with Biowash or what it contain but logically if that product was harsh or your method too aggressive, it would damage the stone quicker than the grout.
Was the grout sealed? Where are those cracks located? If near the pool chlorine from the pool may have cause the grout to crack.

To all Pros,

I have a client who installed brushed polished travertine last year on their exterior pool deck and entry way. Soon after the installation they began having us maintain it every 3 months. Our method of maintenance consists of prespraying the stone with Biowash, allowing it to sit for 5-10 minutes, then scrubbing with a floor machine and a medium duty nylon scrub brush. After that we just rinse all the stone and grout with a water hose.
When we notified our clients to set up our next cleaning appointment they accused us of damaging their grout with our cleaning process. They claimed that there were areas of grout that were missing. They had their installe
r come in to take a look and he blamed us for the grout damage, saying that our cleaning process was to harsh. (He hasn't even seen our process).

I have explained our process to them and that it is not abrasive, no harsh chemicals are used, and if grout were to come out with such light maintenance cleaning, there must be a problem with the grout or the grout installation.

I have also explained that we take care of many homes the same way and with the same stone for 10 years or more and have never had this problem or been accused by an installer (who knows nothing about proper stone maintenance) that our methods are damaging the grout.

I want to be able to show them some statements from other stone professionals from all over the country that our maintenance practices are normal, and even recommended so as not to damage grout. If grout were to be damaged by cleaning so light then something is wrong with the grout.

Is anyone out there willing to help me out
