We soil cream coloured carpet with 4 soils; red wine, coffee, sauces and oil. Reflectance readings are taken of the soiled carpet stains. We follow the directions for applying the product and the amount of time they are left on the stain. The time differs depending on the manufacturer recommendation. Once the product is removed, the reflectance readings are taken and the percentage soil removal is calculated. We do 4 repeats of each stain, or 16 carpet tiles for each product.
We soil light-coloured carpet with different soils: red wine, oil/dirt (blend of oil and a dye), sauce (mix of tomato and soy sauce) and milk coffee. The stains are left to dry over a number of days. The carpet is cut into 10cm x 10cm squares. The reflectance values of the stained tiles are taken before and after cleaning to determine the soil removal percentage. We used several methods of cleaning, according to instructions per pack (we replicate the test a minimum of four times for each tile):
METHOD 1 – 5mL of product is applied to the centre of the carpet square and left for a set amount of time. A damp cloth is then used to massage the product into the carpet for 30 seconds, the carpet tile is then left to dry.
METHOD 2 – 5g of product is applied to the centre of the carpet square and a cloth is used to massage the product into the carpet for 30 seconds. The carpet is left for a set time, then the tile is vacuumed.
METHOD 3 – 5g of product is applied to the centre of the carpet square. The carpet is left for a set amount of time, then the tile is vacuumed.
METHOD 4 – 5mL of product is applied onto the centre of the carpet square and brushed in for 30 seconds, and the carpet square is left for a set time. Then a damp cloth is then used to massage the product into the carpet for 30 seconds, and the carpet tile is left to dry.
Remove excess. Pre treat by vacuuming and test for colourfastness. Shake container vigourously before usage. Do not dampen with water. Do not apply to more than 0.6 x 1.5m area at a time to prevent moisture from drying out. Using soft bristle brush immediately work the powder into carpet. Gently brush until soil disappears. Leave until powder completely dry (at elast 20min). Air room well. Vac the dried powder thoroughly. Change vac bag for best results.
