MASTERCOOL 91049-32-6 Black/Yellow Flush Solvent, 6 Pack (32 oz)

This is a detergent NOT a flush solvent It kills a two ton ac in less than 10 minutes And the item is even NOT RETURNABLE!! angry

This worked great. Buy the solvent spray kit to go with it and you will be happy with the results, if you do it right. My AC system is completely clear of any old refrigerant, oil, and any debris from a failed compressor.

I just flushed the lines and front Evap Core from a 2010 Dodge Grand Caravan. Fluid cleans well and evaporates fast. Evap Core was plugged, this flush broke through the plug very quickly. I didn't get any residual oily film like other users have reported. It did the job it's designed to do and did it well.

I bought this to try cheaper alternatives to rx11 flush. If you don't like leaving solvent in systems then this one is an absolute NO. Tested at home on a burn out 2 ton cap tube dehum. Put about 30 hours on my vacuum pump. purging with nitro over and over, changing vac oil over and over. This stuff doesn't evaporate. What it does do is contaminate and stall my pump. I gave up at 400 microns. Uneasy about the residual solvent in the system, i sent rx11 through it. Purged, pumped down to 50 microns. I have another dehum to fix. Im going to try Johnsen's A/C Flush next.

great product, poor delivery, this stuff is basically alcohol and acetone with some other chemicals..., delivery gave it upside down and lost 1/4 that destroyed the box and neighbors in this complex didn't appreciate it, but not this company's fault, just the inept driver...
