How to Use Skin Salve Laundry Powder – Based on Your Water Type
Did you know that your local water type can affect how well your laundry powder works?




Whether you live in a hard or soft water area, it makes a big difference – not just to your clothes, but to how much powder you actually need. At Skin Salve, our Laundry Powder is made with just a few gentle ingredients – perfect for sensitive skin. But getting the dosage right helps make sure you get the clean you want, without overusing product or causing irritation.
Why Water Type Matters
Hard water contains high levels of minerals like calcium and magnesium, which can reduce the effectiveness of laundry powder. You’ll often need to use more powder to get clothes properly clean.
Soft water has fewer minerals, so detergent dissolves and lathers more easily. You’ll typically need less powder – using too much can cause excess suds or leave residue on clothes.
How Much Skin Salve Laundry Powder Should You Use?
Not sure how much to add to your washing machine? Use this quick guide based on load size, water type, and how dirty your clothes are.
Load Size | Water Type | Powder Amount |
---|---|---|
Small | Soft | 1 tbsp (15g) |
Small | Hard | 1.5 tbsp (22g) |
Medium | Soft | 1.5 tbsp (22g) |
Medium | Hard | 2 tbsp (30g) |
Large | Soft | 2 tbsp (30g) |
Large | Hard | 2.5 tbsp (37g) |
1 heaped tablespoon = approx. 15g
How to Tell If You Have Hard or Soft Water
Not sure which type of water you have at home? Here are a few simple clues:
Lather test: If your soap struggles to foam up, you probably have hard water.
Kettle check: White limescale buildup inside your kettle or around taps suggests hard water.
Online lookup: Search your postcode on your local water supplier’s website for an exact reading.
Troubleshooting: What to Do If Things Go Wrong
If you’re noticing problems with your laundry, a simple tweak to your routine might help:
Issue | Possible Cause | Suggested Solution |
---|---|---|
White residue on clothes | Too much powder or cold water | Use slightly less powder or wash at a higher temperature |
Clothes don’t feel clean | Too little powder or cold water | Use slightly more powder or wash at a higher temperature |
Clothes feel stiff or rough | Hard water or powder not dissolving fully | Use more powder or warmer water; consider a fabric softener for sensitive items |
Suds overflow or residue in machine | Too much powder | Reduce amount used of powder |
Itchy or irritated skin | Residue from excess powder | Use less powder, or add a rinse wash. If the problem persists, discontinue use. |
Final Tip
Store Skin Salve Laundry Powder in a cool, dry place, and always measure carefully. A little goes a long way – especially in soft water!
