"2. Dress your lines ... sometimes. Some lines benefit form a slicione line dressing, while others will simply be clogged. Silicone treatments grather dirt and make cleaning needs more frequent. Generally, low-end lines should be treated, while high-end lines should just be cleaned. Avoid Armor-All and similiar 'protectants" which may draw plasticizers out of the line and make them crack easily."
