Any chance that the cleaning products that are sensitive to light (i.e. red dye, wood stain) could be put in dark bottles to eliminate natural light penetrating the bottles and hopefully increasing the shelf life of the product? I don’t use wood stain remover that often, but hate having to replace it solely due to age. Red dye is used more often and isn’t as big of a concern, although I would love to see the option of these products in a single bottle that doesn’t require mixing. I’ve seen other similar products advertised, and this would save us time/$$ in the field if the product gave the same results.
