Fungus on Torah Parchment

In the Young Israel of Toco Hills we have a Sefer Torah that has vast
sections of the white parchment that have turned light brown, which is
still kosher to read from, but harder to do. A person recently told me
that this light brown overlay is a fungus that grows on parchment and that
there were readily available chemical solutions to fix this that could be
purchased in Israel, which killed the fungus and returned to torah to its
white state without damaging the ink. More than that he did not know,
other than than the fact that there was a machon (he could not name it)
that did this work in Israel.
Has anyone heard of either the machon or the product?
