I haven't had it on my canvas but rubbing alcohol works to get it off of the car. Try that.

And it is cheap too!

I would call a canvas shop and ask before I put a Solvent on the material.

let us know how it works out

Ice makes it hard and brittle but may still leave some residue after you scrape off the pitch.

You can also chill it with key-board blaster.

I haven't looked, but I'm betting there is a recipe out there that uses vinegar. I've discovered this year that there are variants that will take scum off the shower to keeping mosquitoes away....

Trusty WD40 fish oil. I saturate the area with WD40 and let it soak for 10 minutes. The tree sap literally rub off onto a towel. Same for vehicles and vessels.

Why would you not follow exactly what Billy quoted direct from the manufacturer Sunbrella to be safe? Seems like a no brainer to me and trying anything else seems rather chancy......

Thank you everyone for your input !! Both the bow cover and the main cockpit cover had over 100 pitch spots on them

I have tried hand sanitizer in a few test locations and cleaned with soapy water. WOW

the sap is gone and left no staining, or bleaching of the cover

Going to continue and then clean cover completely... My wife found this idea online. I guess I should have asked her to begin with, as dirty as I get working around the yard, when she's done with my mess the stuff always looks brand new.

Thanks again !!!!

Hand sanitizer typically says on the label that the active ingredient is ethanol, a two-carbon chain alcohol (yes, the drinking variety of the alcohol family of compounds; maybe if you sniff enough of it while sanitizing your hands you'll get tipsy!).

Paint thinner takes the sticky gooey sap off....plus there's no harm done to re-waterproofing a tired old boat cover with a gallon of silicone masonry waterproof applied on a dry day with a garden pump sprayer. Wal-Mart prices; gal waterproofer 7.95, 1 gal sprayer bottle- also 7.95 .....the liquid silicone waterproofer goes on sort of whitish.....makes the sunbrella cover look like it is getting wet.....and then dries out to original color....easy to do. A boat cover can last for 20-years of more....hard-to-believe but true....if it is re-waterproofed every other year or so.....and can be done while the cover is on the boat on a sunny day.

VERY interesting----silicone masonry waterproof

?!?

Sounded good up until you spray it while on the boat. Aren't you worried about over spray onto the nicely waxed fiberglass ?? But none the less it's still silicone and once it drys it becomes water repellant, interesting. Thank you.

The Sunbrella manufacturer's recommendation for using turpentine really makes sense in light of the definition of turpentine from Wikipedia:

"Turpentine (also called spirit of turpentine, oil of turpentine, wood turpentine and colloquially turps[1]) is a fluid obtained by the distillation of resin obtained from live trees, mainly pines. It is mainly used as a solvent and as a source of materials for organic synthesis."

I picked some up at Lowe's and I'm going to give it a try on my Sea Ray's black canvas.
