Kind of a new post on a old topic. I have been using zep concrete remover (same as romix backset)to remove old spatter and build up has anyone used this in place  form release oil before pouring?

yep i use this product called cherry release spray on before everyjob and helps with your washout but it like 4.50gallon but safe to use (for in envormemt at my old company we use old used hydro oil and desiel same thing just cost more when msd finds out

crete

i use a chassis spray gun has a long nozzle use engine oil half a liter a day in summer have to use power washer  but comes off no problem i put a portable one on pump

Yeah PeeWee I get the same stuff! I get it from a local hardware supplier called "WhiteCap". Its red colored and smells like cherries! Biodegradable/eviro friendly stuff and it doesnt stain or discolor the assend of your pump either! GREAT stuff!

What is the brand name of the white cap? I am exploring something cheaper to use myself...
