Cleaning Blood and Stains Off Painted Deck (Awgrip Etc) Need Advice

This is the first boat I’ve owned with a painted deck. I believe the previous owner had it painted with Awgrip. I’ve been trying to clean the painted surface with limited success.

Four successive days of fishing has left its mark on the deck. A combination of leaves and fish blood have left stains that I’m struggling to clean. I washed the boat last night after getting home with all three cleaners pictured below. The Hull Cleaner was a last ditch effort. I don’t want to damage the painted surface but would like to improve on what I currently have. Sorry for the poor pictures but I have a boat cover and didn’t fully remove it. Should highlight the stains though.

I’m using a bristled brush.

Thoughts?

im in the same boat, not literally but. just came back from 8 days and cant get blood stains off with dawn dish soap.

I’m just spitballing here but what about bleach or something mildly abrasive like barkeepers?

Magic eraser FTW! Unless you’re concerned about it damaging a painted surface. That stuff works miracles!

Blood is ferrous, you need a mild reaction to remove, hence bleach, diluted 20/80 water. Spray over blood stains let it sit for a few minutes, then flush and brush with soap.

Any mild abrasive like magic sponge and liquid Bar Keepers friend will also do the trick.

Bleach. And then, after you get it cleaned up, make sure to prepare the Awlgrip to prevent future problems. Awlgrip’s “Awlcare” is a protective polymer sealer, formulated to protect Awlgrip, Awlcraft 2000 and Awlgrip HDT from acid rain, environmental pollutants and abrasion. Leaves a non-yellowing protective coat that lasts through multiple washings.

  • Contains no abrasives and will not scratch the painted surface
  • Removes mild stains such a water spots and diesel soot
  • Increases resistance to acid rain and other environmental pollutants

Use that periodically, and then wash the Awlgrip surface with Awlwash. Awlwash is a wash down concentrate formulated to clean Awlgrip, Awlgrip HS and Awlcraft 2000. Contains no alkalis, acids or abrasives.

  • Formulated specifically for Awlgrip
  • Free-rinsing formula for faster drying

Try hydrogen peroxide. It reacts with blood and foams it off. It works on Sea Deck and the cap on my skiff even when blood is dry. I don’t know exactly the finish on my cap, though so it may not work on yours.

I can also tell you it works nicely getting blood stains out of clothes. Mine, to be exact. I have quite a bit of experience with that.

@ shallow_dan beat me to it. My wife is a retired veterinary tech. She dealt with dog & cat blood for 30 years.

The #1 treatment for blood stains is hydrogen peroxide, in her book. May not work on the leaf stains but I’ll bet it will remove fish blood.

As other said hydrogen peroxide. Home Depot sells it by the gallon.
