Cleaning ground glass

[D.M. Procida]

I've got some lacquer onto glass panes; the parts that are smooth are easy to clean with a rag and meths, but the obscure ground parts much less so.

Is just more rubbing required, or is there some special technique that will help?

================================================

Try a *brass* wire brush. Available from Screwfix and most Car spares shops.

As anything abrasive will show I would have thought paint stripper would be better than abrasion.

A lot depends on how you use the brass brush. As an example I can take crap of french polished wood with steel wool and not damage it. Mind you thats after years of experience renovating stuff.

I think I would start with a tooth brush first. That shound never stratch anything.

Depending on the lacquer, I'd start with solvent. Maybe acetone / nail varnish remover? Cellulose thinners (methyl ethyl ketone)?

[Gib Bogle]

Use lacquer thinner (whatever it's called). It's a much more powerful solvent than meths or turps.

i've found Hammerite thinners [naptha, I think] to be a very powerful solvent, but I'm no chemist so can't vouch for how it would work on lacquer.

hammerite thinners = Xylene?

When I first used hammerite thinners I was quite amazed at just how volatile it was - on a warm day it looked more like a thick gas or mist in the can than a liquid. Anyways... you got me thinking, so from the hammerite site;

aha... yes a little further googling reveals:-

"26-03-2007, 07:03 PM ok, hammerite is ok and for info, is no longer xylene based! It will now wash out with white spirit. Over the last 5-6 years the formula has been changed quite a lot, incidently, I'm a buyer in a decorators merchant so need to know this stuff ;), personally, I wouldn't touch the stuff. We did a test on mild steel with hammerite and a product called rustoleum combicolor straight onto a mildly rusted plate. side by side application, this was 3-4 years ago, within 3 months the rust came through the hammerite, 3 years later the rustoleum was still good, use it on all my rust spots, on the car! Hope this is of some use."

also google in UK.DIY for "Hammerite Thinners" sums it all up (recently)

Ah right. I confess it was about 5 years ago when I last used it, so what formula it was I don't know. Shame if they've changed it cos in my - admittedly very limited - experioence it used to be good stuff.

[JimK]

indeed - I've used quite a lot with good results on home made mild steel railings, gates and balconies etc - no idea what formula my tin has in it til i check.....tho twas within last 3or4 yrs that i purchased (screwfux) so unless "old stock" presume is the new alleged "lite" version - still seems good tho - no probs so far for my stuff.

Acetone will dissolve it (nail polish remover).
