And once again the weird 'WC gel' that Lidl sells saves my ass. Years of caked-on oils and grime on the shower walls gone with basically no work or executive function required.
I don't really understand why nobody else seems to sell this stuff, or even really what is making it so effective compared to normal bleach or even toilet cleaner...
For those in NL, this is the one: https://www.lidl.nl/p/dikke-bleek/p44285
The equivalent in Belgium is this one: https://www.lidl.be/p/nl-BE/wc-gel-met-javel/p10000124
(You may find the Belgian one in Dutch branches sometimes, instead of the Dutch one.)
Pay close attention to the label and the bottle designs because they have a bunch of products that *look* similar but aren't.
