To put together a list of the best chemicals you will buy from many places.
I buy prespray from joe b. and EasyExtract (one is powder and one is liquid).
I buy my boosters and whatever I can from Godfathers supply in Sandy UT.
I buy deo from Bestway janitorial in SLC.
I buy the odd this or that from
Superior in Orem.
And I buy occasionally from
Jon Don when the friendly salesman calls me just to see how I am doing.
