Where do you get ( how much do they cost) you buckets that have lids and small openings for the detergent hose to go through? Also, how do you go about mixing detergents? Do you always use the same bucket for the same chem?
Call your local container company. I had some buckets so I took one to the supplier and he had some of the lids with the pull out clear spouts with the black cap for $2.25 each. The Buckets will run about $2.50 and up from there depending on how many you want. The supplier will have several catalogs that you can look through and see what you want.
i do it wrong im shure but i mix in the same bucket time after time ,but i do rinse it well after each use.the exception is i have 4 chem tanks on my truck that will hold 15 gallons each
