Cleaning Wagner Spray Gun

[Eokitoo]

Hi, I have just bought a good Wagner spray gun for spraying the vj walls on an old house that I rent. No problem with the gun, in fact it is a great time saver in painting the vj but the problem that I have is the cleaning of the gun afterwards. I am very fussy with my equipment and always give my tools a good clean after use. ( well nearly always) Is there a fluid out there that I can spray on the gun previous to use so the paint wont stick to the plastic housing. Thanks

I just bought one of those same guns, I was using water based acrylic type paint and found that as soon as I was finished I dropped the parts(with the exception of the electrical parts) into a bucket of fresh water and soaked them overnight. Next day all that was required was a light scrub with a nylon bristled brush and a little detergent then a rinse. But lets face it it's a spray gun and it will get paint on it, I'd be a little careful putting any chemicals onto the plastic housing as they can melt it, or over time make it brittle shortening it's life a lot, at least the paint will offer some protection!..

Anything you can put on the gun to stop paint sticking will also get in with the paint being sprayed & stop it sticking to whatever you are spraying it on - in thousands of little spots :eek:

As Savage said, give the bits a good soaking & scrub with an old toothbrush (or an el-cheapo) - if that doesn't shift the old paint, you may need to resort to some chemical bath - Artists pen cleaner is good, just don't leave the metal bits in it overnight as the stuff eats chrome off brass parts or paint stripper - most of the plastic bits are immune to paint stripper - usual warning applies.

When I bought mine the guy instucted me to use diluted coolant. This then had to be run through and disposed of until it went though clean. (recycle though bucket) He indicated that this ensures that all paint is removed and leaves the inside of the gun coated with the coolant.

I have the wagner W300, I use it at work to spray thinned warm chocolate onto finished products, I always pull it completely apart and scrub all the parts but the motor with detergent, leave it to dry and then re-assemble next day, lubrication is with machine oil, and after 4 years not a problem or a mark on it.
