Keep your fly line performing at its peak with the S.A. Fly Line Cleaner Rinse Free 4oz Bottle from Scientific Anglers. Designed to restore the line’s natural flotation, this rinse-free cleaner removes the embedded dirt that weighs your line down and dulls casting accuracy.

Why flotation suffers: fly lines float because they’re lighter than water and have a hydrophobic surface that repels moisture. When dirt builds up on the coating, water no longer beads off as effectively, and the line starts to sink a little with each cast. A quick clean can bring back that cast-control and lengthen the life of your line.

What makes this cleaner stand out:

• Biodegradable formula that’s gentle on the environment and tough on grime
• Rinse-free use means you can refresh lines on the go without a shower of water or residue left behind
• Specific for AST and AST+ lines while still effective on all fly lines
• Fast, simple process—simply soak, wipe, and rinse (as needed) to restore line performance
• 4 oz bottle provides ample cleaning sessions between trips and helps maintain line longevity

How to get the best results:

• Soak a short section of the line or a small cloth in the cleaner to loosen surface dirt
• Wipe the line thoroughly to remove embedded grime and restore the hydrophobic coating
• Rinse lightly if desired, then dry and prepare for casting
• For enhanced flotation and durability, follow with S.A. Fly Line Dressing

Ideal for anglers who demand reliable, clean line performance across a day of fishing—from pristine streams to muddy riverbanks. Regular cleaning, roughly every 2–3 outings or anytime you notice bogged-down casting, can noticeably boost flotation, casting consistency, and line longevity.

With Scientific Anglers’ proven expertise in line technology, this cleaner helps you reclaim the true, effortless feel of your line. It’s the practical, no-nonsense maintenance tool every fly fisher should have in their box.
