I need the help of my esteemed and knowledgeable Forum colleagues, I now have 5 tins of Humbrol Matt spray varnish on which the nozzle is blocked with only half of the tin used up at best. Does anyone have any suggestion on how to clear the blockage? I always spray the can upside for a while after use and I have even tried soaking the nozzles in turps overnight to no effect. Any ideas?
Can't you transfer a spray nozzle from another aerosol cannister?
I have never had this happen. My only advice would be to try putting it somewhere warm for a while to see if that helps
Wow, that was quick work chaps. The problem with transferring a nozzle from another can is it has to be either a new can and unused or from the same type of can, I wonder if on ebay you can get just nozzles? I also keep my spray cans indoors as they have been affected by frost when kept in the shed.

Only had it happen once and I managed to clear the nozzle with CAREFUL application of a sewing needle. I levered off the plastic nozzle and worked on it from both ends of the opening. Certain amount of gentle poking and prodding required, having a thimble to hand was definitely useful.
I am assured that attempting the same on the can itself is something you do not want to do and that ignoring this advice is something you will only ever do once!
I've seen it tried. Amusing but messy.
Hah! a quick search on ebay, a pack of 10 new nozzles for £2-99 now on it's way to me, has to be worth a try?
I may also get a needle out later and try that idea but only on the nozzle. Reminds me of when at college when some friends and I borrowed a keg of beer from the college bar and when we whacked the nozzle with a screwdriver we all got covered with beer spraying out all over the place. Even worse, we were doing this in my room which stank of beer ever after!
When I used spray varnish waaay back in the day I always cleared the nozzle by turning the can upside down and spraying the residue out. Then I took the nozzle off and kept it in a small jar of turps until needed again. Quick clean with a piece of tissue or an cotton bud and off I went. Never had a blockage while I was doing that.
I think the lesson here is apply varnish by brush. I started doing this about ten years ago and have never looked back. I use Vallejo and Windsor and Newton acrylics.

I'll stick with spray cans :)
