MasterBlend has developed the best product we’ve seen on olefin carpets (polypropylene). Very concentrated at 32:1 and extra aggressive on oils and greases. This product packs a punch in cleaning oily, greasy olefin traffic lanes (or any traffic lanes that do not respond to regular presprays.)
Ready-to-use pH is 10.3
Extra aggressive on oils and greases.
Mix 1 part Olefin Prespray with 32 parts hot water (4 oz per gallon of water). Mix well and apply to carpet. For use with an in-line sprayer use undiluted with the 32:1 metering tip or mix 1.5 quarts of Olefin Prespray with 3.5 quarts water. For best results agitate with a pile brush or rake.
