If you have a tough mineral stain that won’t budge, try these solutions. Drain the bowl and rub with a paste of Wendyl’s Green Goddess Premium Borax and a little water. Leave as long as you can, then wipe off.
Spray Green Goddess Double Strength White Vinegar around the inside of the toilet and under the seat or anywhere stains and germs may be hiding. Leave for ten minutes then wipe clean.
If draining the bowl sounds like a mammoth effort simply put 1 cup of Wendyl’s Premium Borax straight in the bowl and leave overnight. Finish off with the toilet brush and flush in the morning. You may have to do this several times for hard to move stains.
