I always get a kick out of CRL Sprayway Glass Cleaner S50 and its affect on the ladies. It seems that the aroma from this foam cleaner is the alluring factor that makes this product so popular. One of my eBay customer's Feedback comments was that his wife is now very happy. When comparing CRL Sprayway Glass Cleaner 1973 to S50, both do the same excellent foaming action cleaning but the S50 wins the aroma test. It's a favorite in my house!
