Spoon and beads

ComStar Pure Lye® Beads

Drain Cleaner – 99% Pure

ComStar achieved a perfect balance when Pure Lye beads were produced small enough to dissolve in water, yet still had the weight to sink through standing water to break up even the toughest organic clogs.

No water or colors or fillers like traditional store-bought drain cleaners. Just the stuff that works — in the ideal form.

  • Biodegradable and environmentally safe
  • Will not contaminate water
  • Can be used on chrome, metal and plastic
  • Can also be used to make soap

Beads are easy to pour. Won’t spill.

Make your own soap

ComStar Pure Lye® is the perfect base for handsome soaps you can use at home or gift to friends.

Soap making can be very simple or you can make it as complicated as you like. The beauty of making your own soap is that you can make it with the ingredients that you choose and the fragrances that you like, such as herbs, essential oils, colors and moisturizers.

Spoon and flakes

ComStar Pure Lye® Flakes

Soap Making – 99% Pure

The consistent purity of ComStar Pure Lye® also attracts soap makers. The best soap crafters won’t stand for fillers or dyes. They need it white and bright and contaminant-free.

ComStar introduced Pure Lye flakes which don’t cling to fingers or tools and dissolve quickly. Pure Lye flakes are a soap maker’s dream.

  • Won’t static-cling to tools and hands
  • Easy and safe storage
  • Odorless

The flakes are large but dissolve quickly
