[Non-Tech] Descaling for 1/3 of the price

Totally non-techy post ahead:

Most supermarket/shop descaling powders (the little sachets) work out at about £15/kg, given that all they contain (for the vast majority of them!) is citric acid, it works out a lot cheaper to just buy Citric Acid in bulk (Amazon link: 1kg Citric Acid for £5) and use exactly the same quantity.

About Rob

I've been interested in computing since the day my Dad purchased his first business PC (an Amstrad PC 1640 for anyone interested) which introduced me to MS-DOS batch programming and BASIC.

My skillset has matured somewhat since then, which you'll probably see from the posts here. You can read a bit more about me on the about page of the site, or check out some of the other posts on my areas of interest.
