I have recently painted using Hammerite metal paint. When I tried to clean the brush afterwards using White Spirit, I noticed it didn't work. Hammerite sells a specialized cleaning product, but I'd like to use a product that is useful in other situations too. Is there anyone who knows what kind of cleaning product might help?
The consensus of opinion on the Ultimate Handyman forum seems to be to use an old brush and throw it away after use.
A couple of alternatives are suggested:
Ordianry cellulose thinners will also work.
So presumably the Hammerite product is cellulose thinners based.
I wrap mine very tightly in plastic and stick them in my brushmate, as long as i use them every couple of months they stay reasonably soft, even if they go a little stiff a drop of hammerite thiners brings them back to life.
Which is something I do overnight (or a couple of days at most) when using gloss paint. It does keep the bristles soft for a while so saves on white spirit and having to find a clean brush for the next coat.
