Top notch company.

Item was exactly as described and installed very easy. Shipping took a little longer than expected but was due to UPS. Would highly recommend.

Fast Orange Grease X laundry soap cuts through the oil well!

Fast Orange Grease X laundry soap cuts through the oil well. I have spent weeks treating my son's clothes with Palmolive and other degreasers. They only took care of the surface oil and dirt. I did not have to pretreat with Fast Orange.
