Instructions for using MSB

The following instructions can be found on the back of each bottle of Mrs. Stewart’s Bluing:

Always dilute bluing in cold water BEFORE adding to wash load or rinse water.

  1. Mix a few drops or up to 1/4 teaspoon of bluing (depending on wash load size) in a quart or more of water.
  2. Add diluted bluing to wash water or final rinse (water should appear light sky blue).

Instructions-for-MSB-ThumbDetermining how much bluing to use depends upon the load setting of the washing machine and whether it is being used in the wash water or in the rinse water. Generally, when using Mrs. Stewart’s Bluing in the wash water, use approximately 1/4 teaspoonful and if used in the rinse water, less than 1/8 teaspoon. Always mix the bluing in a container of clear, cold water before pouring into the machine. Avoid pouring bluing from the bottle into the machine when clothes are present, as any fiber can absorb an excess of undiluted bluing, causing spotting. An easy way to use bluing is to measure the bluing into an old empty 2 quart or gallon pitcher or container and fill with cold water. Then it can be poured into the machine with clothes present, in either the wash or rinse cycle.

We do not recommend that bluing be used in conjunction with bleach and/or fabric softener. There is no worry of hazardous chemical reaction. However, we do know
that bleach encourages more permanent adherence of bluing to fabric and it is generally recommended by most fabric softener manufactures that fabric softener
not be used in conjunction with any other laundry product. It is important to know that bluing is not a stain remover, it is a fabric whitener. Bleach is very good for removing stains but can damage your fabric easily. Bluing is very gentle on fabric and will not harm the fibers.

We do not recommend dispensing bluing from your automatic fabric softener dispenser as most dispensers are not large enough to allow for enough dilution and
spotting can occur. We also do not recommend soaking clothing in bluing water. A simple dip or rinse is sufficient.

For re-bluing faded denim jeans, use more bluing than directed.
