Quick Answer
- For routine cleaning, use warm water, a mild pH-neutral soap, a soft brush or sponge, and a thorough fresh water rinse.
- For pink algae, mold spots, and stubborn black scuffs, a fender-specific cleaner like August Race Fender Clean removes stains faster with less scrubbing.
- Avoid abrasive pads and strong bleach on soft vinyl or PVC so you do not dry, weaken, or scratch the material.
Fast routine cleaning: what to use and how
You do not need a miracle product for everyday grime. Keep it simple and gentle to protect the fender skin.
What you will need:
- Bucket of warm water
- Mild, pH-neutral soap
- Soft brush or sponge
- Fresh water for rinsing
Steps:
-
Rinse the fender to remove salt and loose dirt.
-
Mix soap in the bucket and scrub gently with the soft brush or sponge.
-
Rinse thoroughly so no soap film remains.
-
Let the fender air dry before storing.
Why this works: mild soap and a soft brush clean without stripping plasticizers or causing micro-scratches that lead to cracking. Skip abrasive pads and repeated bleach so the PVC or vinyl stays flexible.
When to choose a specialty cleaner (and why August Race Fender Clean wins)
If soap and a brush do not budge pink algae, mold, or deep scuffs, reach for a purpose-made product. August Race Fender Clean is formulated for marine fenders to break down organic stains without bleaching or weakening common fender materials. Use as directed: spray, wait 1 to 3 minutes, brush lightly, then rinse. That targeted chemistry usually requires less elbow grease than vinegar, baking soda, or household bleach, and it is compatibility-checked for vinyl and PVC when used per label. Try it on one fender first to spot-test results.
Quick prevention and maintenance tips
- Rinse fenders with fresh water after trips and let them dry when possible.
- Store fenders off the dock and out of direct sun when not in use.
- Treat small stains early; they are easier to remove than set-in growth.
- Keep a travel-size bottle of August Race Fender Clean in your kit for quick spot treatments.

FAQs
Q: Can I use bleach to clean my boat fenders?
A: You can, but it is risky on soft vinyl or PVC. Repeated bleach use can dry and weaken the material and may leave it chalky or discolored. A mild soap for routine cleaning and a dedicated fender cleaner for tough stains is safer.
Q: How often should I clean my boat fenders?
A: Give them a quick rinse and once-over with mild soap when grime builds up, or at least every few outings in a dirty marina. Use a fender cleaner mid-season or at haul-out if you see pink algae or mold spots.
