Block cleaning

There are other spray lubricants that contain less alcohol or no alcohol that will mot evaporate. One the surfaces are completely dried and sprayed with lubricant I would suggest you wipe down the machines surfaces with oil or grease until you are ready to assemble. The longer time span from cleaning to assembly the more important the lubrication is.

I usually use Amsoil engine fogged or a couple other spray lubricants vs. WD40.
