Welcome to the life of owning a carwash! Very little sleep in the beginning and lots of worries!
I had issues with
soap thickening in the buckets in the winter...Been years ago....I Had the 5 gal buckets on the concrete floor....Ever since getting them off the floor, I have never had any issues. (Plus I keep the ER @ 60° minimum) I put the full containers of
soap on top of other 5 gal buckets....For a small wash like yours, I would never consider getting anything bigger than 5 gal buckets. You've learned a valuable lesson early on...I don't know if you can save that drum of FB
soap, maybe some others will chime in. I've never had any
soap separate and don't know if it can be stirred and it stay in solution....I only use Warsaw chemicals that are top of the line IMO....And everybody has there own opinion, LOL...
Soap quality means everything. Always lots of discussions on here about different soaps and quality...
A suggestion to get you by for now, just use HP
soap for your FB
soap....There are a lot of guys on here that do it that way....You'll just have two hydrominders with HP
soap, one for FB and one for HP....
BTW, a 5 gallon bucket of
soap lasts me a very long time....There is magic involved to get
soap to come out thick and rich but use very little. Stick around here and read some old posts and you'll figure it out!!!!
