Tree Resin ?

[OceanSprint]

Cleaned my boat. Polished my boat. Parked it under trees on trailer (I think some kind of sycamore), and now decks and cockpit covered in brown stains - resin ? Won't wash off.

Any advice? Help !

turpentine is made from tree resin (the genuine turpentine, that is).

It worked when I needed to remove acacia droppings in Oman.

Sure no ones been using a grinder nearby? Oxalic acid ( or Y10 ) if it's rust stains

Always thought what comes off trees was excrement from insect life on the trees but that washes off ... with some difficulty

dunno about sycamore trees, but for lime trees it's the aphids eating the sugary sap from the leaves and petioles, and then excreting excess sap onto cars.


Turps works. (? torps wurks, terps werks....)

I know what it is coming down from the silver birch onto our cars ! Fecking pigeon sh*t.

Resin is in my experience (my works car park has a number of enormous pine trees alongside) clear/white glue-like stuff, which can be removed with olive oil and elbow grease. I'm told that white spirits (ersatz turpentine) also works.

My strategy is:

Use thumbnail (or old credit card) to remove excess.
Soak tissue in olive oil then leave on residue
Come back half an hour later with hot water & Flash (yellow liquid floor cleaner) and scrub...

If the stuff has gone hard, then the job is much more effort, but sometimes the resin weathers enough to come away with just the thumbnail.

Having seen what oxalic acid does to chrome plate I won't be trying it on the car anytime soon, but it does seem to remove anything from the boat...

I usually have to park under a sycamore tree and suffer the same problem; it does come off with warm soapy water and a stiff plastic brush, but if possible try to do this regularly so as not to let the stuff set too hard or build up.

There's a pigeon nesting in the tree as well, just to add insult to injury...

It's always washed off mine easily with water but don't leave it for long. it seems to damage the paint finish.
