I usually shampoo the carpets with my ancient (circa 2002) Bissel Quick Steamer with VERY HOT water, a huge splash of vinegar and some baking soda but last night I put a table spoon of baking soda, a table spoon of Borax, and a splash of vinegar. The stain is considerably lightened, it's still there, but I'm sick and I didn't much effort into it.
- 1 T Borax
- 1 T Baking soda
- 1/2 C White Vingar
- 3 C HOT water
Mix under the faucet in the tank and use in the cleaner. As an alternative, mix in a bucket and apply liberally.
Not sure if this would void the warranty on the thing but after it runs out, it doesn't matter does it?
