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...
