Betco Extreme anything else is a waste of time and money in my not so humble opinion. No I don't sell it but from someone that has stripped and waxed 10's of millions of sq ft at .35 a sq buy the one that cost more and saves on labor. My boss about blew a gasket the first time he noticed my P&L chemical cost then I showed him the labor cost for those same jobs. Every area manager was using it the next month.
