I've been fighting the constant increase in prices for paint brushes because I am too lazy to get up from the bench, walk to the kitchen and rinse out the brush before either using another color or ending my painting for the day.
The result has been "contaminated" brushes with either off color chunks of paint or worse still, small pieces of matter which have the habit of popping off the brush and onto the glass smooth surface I am working on.
This usually means throwing away a bunch of brushes and making a trip to the crafts store for some new ones.
Frankly, I never heard of a flip-top plastic bottle with an in-the-neck reservoir that allows me to dispense fluid into the little neck cup that won’t backwash into the main bottle’s contents.
That is the case for a few of the bottles used for Johnson and Johnson Act brand mouthwash. Yes, I bought a whole bottle of mouthwash solely for its bottle.
It is an otherwise clear plastic bottle resembling a myriad of mouthwash containers except for the barely visible whitish reservoir in the neck of a few. The purpose of the reservoir in a mouthwash bottle was to provide the precise amount of the product (10 ml) to correctly get the job done.
Guess what, 10 ml is exactly the amount of the water/Windex mix needed to clean a brush. I just squeeze the bottle to fill the little holder to the fill line, swirl the paint-filled brush in it and then dump the contaminated cleaning liquid.
