Agent X
Do not use on full sinking or the sink tip of a line. Agent X is a line cleaner/ conditioner that will make the line shoot further. Apply to your dry line with a soft cloth, wait 5 minutes and buff with a soft cloth. For optimum performance, wait 24 hours before buffing. SHAKE WELL.
A fly line gets dirty like anything else, and should usually be cleaned every few trips. Rio's Wonder Cloth is a micro abrasive fly line cleaning pad that strips out the deep lying dirt without roughing the fly line. Apply a thin coat of AgentX line dressing after use for maximum benefit.
2 versions - one with solution only. One with AgentX and Wonder Cloth.
