Keep a handy measuring cup with every concentrated product.
The Attach-It Measuring Cup hangs around the neck of just about any bottle so it's always there when you need it. The 3 oz. measuring cup has the volume marked on the side. Hang an Attach-It Measuring Cup around each of your concentrated detailing products. By giving each product its own cup, you'll avoid the cross-contamination that occurs when reusing the same cup. Use Attach-It Measuring Cups with shampoos and concentrated cleaners. Attach-It Measuring Cups are sold in packs of three.
