Trial #1
To evaluate the supplied products for Marble surface cleaning effectiveness.
There are no related objects.
First, 2 marble coupon tiles of the same size were obtained; 2 coupons each for the two supplied cleaners. The initial weights of the coupons were acquired in order to use it as a standard and also to determine how much of the marble was dissolved after immersion in the cleaners. The marble coupons were subjected to immersion in the cleaners and observations were noted for 1 minute, 5 minutes, 10 minutes, 15 minutes, and 30 minute intervals. After the 30 minute mark, the marble coupons were then rinsed with tap water for 15 seconds each to rinse away any of the remaining cleaners. Then, each marble coupon was dried using a heat gun set at 300° F for 30 seconds each. Finally, the mass of each marble coupon was then noted to record any change in mass.

It was found that the worst performing cleaner on the marble surfaces was the Lysol Power Bath. Visually, it had less fizzing action when compared to the Citrus cleaner. The Lysol cleaner also dissolved less of the marble coupon; only 1.17g. When compared to the Citrus Cleaning ES cleaner, the Citrus cleaner performed much better. Visually, it was seen to provide substantial fizzing action when it was applied to the marble coupon; at 5 minutes marble precipitate started forming at the bottom of the beaker. The Citrus cleaner even dissolved the marble coupon to a greater extent than the Lysol cleaner. The marble coupon of the Citrus cleaner was found to have been dissolved by 2.04g when the initial and final weights were subtracted, supporting the fact that it performed better than the Lysol product.
