A Foamy & Natural DIY Upholstery Cleaner 

🌱 DIY Green Cleaning Recipe
By Analisa from Under Your Sink

 

Upholstery cleaning can be a bit of a minefield - you’ve got to be careful about what type of fabric you’re spraying and how much moisture it can handle. I’ve found that soap actually solves a lot of problems when it comes to stains and smells, but it can leave the fabric too wet, which isn’t ideal.

So, I experimented a bit. One trick that worked well was blending up the Castile soap first - it turns really airy, almost like a foam, just like those store bought upholstery sprays. It made the mixture lighter and easier to use without soaking the fabric. I’ve tested this out a few times and found it really effective, so give it a go and see what you think.

An added benefit of using soap is its pH. Soapy water usually sits around pH 8-9, which makes it mildly alkaline. That’s enough to cut through oils and everyday dirt, but still gentle compared to stronger alkaline cleaners like washing soda (around pH 11). Being closer to neutral means it’s less harsh on delicate fibres and safer for surfaces that can’t handle strong alkalinity. It’s a simple balance: effective cleaning power without the risk of damaging your upholstery.

  • 💡 Tips 

    Before going all-in, always do a patch test in a hidden spot -especially on delicate or unknown fabrics. Even gentle, natural ingredients can surprise you depending on the material. Better safe than sorry!

Common Questions

Can I use this on all types of fabric?

Always patch test first. While the ingredients are gentle, every fabric reacts differently - especially delicate or vintage upholstery. Pick an inconspicuous spot, apply a little, let it dry, and check for any changes.

Can I use essential oils in this recipe?

You can, but go easy - especially if you’re spraying on areas that pets or sensitive noses frequent. Some essential oils can cause staining or skin irritation, so stick to small amounts and avoid direct contact.

Do I need a special cloth or brush?

Not really, just avoid anything too abrasive. A soft cloth should will do the trick.

What should I avoid when cleaning fabric upholstery?

Avoid soaking the fabric - too much moisture can lead to mould, water stains, or damage to the padding underneath. Also steer clear of harsh chemicals, vinegar on natural fibres, and scrubbing too hard, which can wear down the fabric. Gentle and minimal is the way to go.
