This is an update after my previous post about disposable washcloths.

In that blog post I wrote that I didn’t think the argument of “*disposable washcloths are cheaper than normal ones*” was valid. After doing some math (and I’m terrible at that) it turns out I was right!

Here are my findings:

1 pack of disposable washcloths cost € 0,69.

1 x 6 KG load of laundry (60C) costs € 0,92.

1 normal washcloth weighs in at 35 grams on avarage.This means there are 171 washcloths in 6 KG of laundry.

If we do a simple sum it comes to this:

- 1 disposable washcloth costs € 0,14
- 1 normal washcloth costs € 0,005

If we make it a bit more awesome, it comes to this:

- 171 normal washcloths in 6 KG of laundry cost € 0,92
- 171 disposable washcloths (compared to 5 normal) cost € 23,60

That is if we would use 5 normal washcloths for each person every day!

But we never use that many. We use 1 or 2 at most. So let’s do this sum again, only comparing those 5 disposable ones we have to use (or throw away) each day to the 2 we normally use:

- 171 normal washcloths in 6 KG of laundry cost € 0,92
- 171 disposable washcloths (comapred to 2 normal) cost € 58,99

So, in conclusion; If we pay less than € 3,99 a KG to the company doing the laundry, normal washcloths are cheaper (171×0,14:6=3,99).

Remember, this is comparing the disposable washcloths against the cost of laundry of normal washcloths. I did not take into account the cost of buying new washcloths. I didn’t think that was neccesary!

I will take this up with my manager as I really think this is not cost-effective at all!
