Vacuum the entire carpet the first day it is laid, and then daily to every other day from then on. The frequency of cleaning will be determined by the traffic in the area and the amount of debris it acquires daily. Make sure to vacuum all areas including corners and along walls to keep debris at a minimum. Any debris that falls beneath the carpet or is pushed there by accumulating along walls will cause holes to develop over time. If there are any strings hanging out of the carpet, snip them with nail clippers to keep from unraveling.
Add hot water to the carpet cleaner. It is recommended that steam cleaners be used, as this not only rids the carpet of debris, but helps in the drying process. The longer water stays on the carpet, the better chances are that mold will set up on the padding underneath. It is best to use only hot water to clean the carpet for the first time, and this should be done within 2 days of the carpet being laid. This will get rid of excess dyes and debris that are lodged in the mat of the carpet. Subsequent cleanings should use the recommended cleaner or detergent that comes with or is made for your cleaner.
Use the scrub brush dry on the floor in high traffic areas to help keep the mat and fibers standing up. You will notice that in areas that are walked on often, the carpet will lay down and look matted. The best way to fix this is to use the scrub brush daily to brush against the mat. This will pick the fibers back up and help them to not show signs of wear.
