*	Test procedure: First, all surfaces were sanded to a matt finish (180 grit, 320 grit and grey-green scotch brite). The listed reagents and stains were placed in contact with the product surface under a 1” diameter cover glass for 16 hours prior to evaluation for effect. All stains/reagents were tested with the following cleaners for stain removal as specified by NEMA LD3-1991 stain test.
		Tap water to remove excess reagent from surface. Acetone applied to each stain with a squirt bottle. 50:50 volume mixture of naptha and ethyl alcohol.
	The samples were then evaluated and the results reported/judged as follows:
		No effect or noticeable change in colour. Slight effect or slight change in colour with no surface damage. Moderate effect or change in colour with minimal surface damage. Severe effect graded in two ways –
			A – Surface structure damage B – Severe stain remaining

Comments:

The result in the “Result After Cleaning” column was obtained after the top was renewed following the Care and Maintenance guidelines documented in this brochure.
