Several of you said the results of tea or coffee soaking would be modest. So, after my no-results experiment with the white plastic spoon, I thought there would be very low risk in a small test spot on the pickguard itself.
Dabbing tea, no affect. Letting it sit a few minutes. Zip.
Coffee, the same 2 experiments. Nada. Urine crossed my mind.
I'm thinking of a light spray of Fender Neck Amber. But the last thing I want is a pickguard with scrapes through to the white saying "I've been sprayed with Fender Neck Amber and now I look like it, don't I?" 🤮
So maybe I'll just let it be.
