I just pop it all into the tank. I usually let a part sit for a while. Time is of no consequence (or at least it wasn't a while ago
), so letting the part sit an extra 24 hours is no biggie. The average length of time for a cleaning cycle is 48 hours which is just arbitrary, but I have found that grease, goop, dirt, 99% of the paint and all of the rust is usually gone or removeable with the 4-1/2" grinder and a twisted wire brush.
Judging by your questions, it might be an idea to expand on the topic and put in a how to. This is not the first time and probably will not be the last time this question was asked.
Oh, also, it probably isn't needed. But I sometimes I will top up the tank with an extra cup or two of TSP. There is a point where it will make no difference, but that I doubt would be reached before one needed to drain and clean the tank.
In defference to Dan, I kind of disagree. I would never put Drano in the tank...... Drano is pretty caustic on it's own. Adding it to TSP or Washing Soda is to my mind kind of risky seeing as I regularily have my hands in the tank. Power off of course
Again my friend, thank you for the step. It arrived last night and it is a beautiful example of fine craftsmanship. From one to another - well done!
And the pics on your site are awesome - I am really looking forward to seeing the info on the 3 point hitch.! Just don't be looking at me to build a 6cyl Cub -- awesome !!!!!!
