The renters left several things in our garage and the old garden furniture was totally rusted and therefor unsafe to use after being outside in Houston's weather for more than 3 years.
So we bought a "bagster" and worked hard. For those who don't know what a bagster is, it is a big bag you buy in a DIY store, fill up with your big trash, then book and pay to get it picked up.
Looks as though you are having a good clear out. We have two free Council bulk waste collections a year and we book a collection date and then put our 'big trash' on the front kerb for collection. We have just used our second collection as we had two good clear outs during lockdown etc.
