I am in the UK. I think Tippex is not available in the US.

These days correction fluids like Tippex seem to have been
reformulated compared to several years ago.

That sounds similar to "White-Out" in the US, and my comments below
assume the UK version is similar to the US version.


I think the old chemicals used were too hazardous and the dilution
fluid for them was something hazardous like 1,1,1 trichloroethylene.

While that name is chemically impossible, I believe the solvent used
to be either 1,1,1-trichloroethane or 1,1,2-trichloroethylene. In my

It was 1,1,1-trichloroethane.

I've used methylene chloride to rejuvenate White-Out in the past. It
resuspends the pigment very well, but it doesn't work great--it
evaporates too quickly. I would try some trichlor (electronics
supply shop?) or methylene chloride (hardware store, as furniture
stripper), or maybe toluene (hardware store--paint thinner or lacquer
thinner).

Yes DCM will work. You need a halogenated solvent for Tippex.
DCM also tends to make the plastic bottle a bit "soft" and it dries way too
fast.
I would guess dichlorethane or maybe perchlorethylene would work well
