Over the years I've leaned on my own maintenance utility — CCASAM — to tidy up the machines that come through the workshop. It did the job, but it had grown old. So I did what I'd tell any customer to do with tired kit: rather than patch it up again, I rebuilt it properly. Chiltern Cleaner is that rebuild — a modern, safety-first cleaning and maintenance tool for Windows 10 and 11, and the direct successor to CCASAM.
The most important thing first: it's free with any of my PC services — Bronze (£50), Silver (£75) or Gold (from £125) — the software side of what I do (see the service packages for what each covers). No subscription, no locked "Pro" version, no adverts, and nothing bundled that you didn't ask for. I set it up as part of the job and show you how it works.
Why a repair shop makes its own cleaner: I clean up dozens of slow, cluttered PCs a month, so I know exactly which junk is safe to remove and which "optimisation" does more harm than good. Chiltern Cleaner is the tool I actually want to use on your machine — cautious by default, with every risky step backed up first.
What Chiltern Cleaner Does
It's built around one idea: give you a proper workshop-grade toolbox, but make the safe choice the easy one. Here's what's inside.
Cleaning & freeing up space
- Browser cleanup for Chrome, Edge, Firefox and Brave — caches and temp files by default; cookies and history only if you choose them.
- Windows cleanup — temporary files, the Recycle Bin, thumbnail cache, and other clutter that quietly eats your drive.
- Duplicate finder, large-file scanner and empty-folder finder to reclaim space you didn't know you'd lost.
- Disk analyser so you can see, at a glance, what's actually filling the drive.
Making the PC faster
- Startup manager — stop the programs that slow your boot to a crawl.
- Boot-time analysis and a system health score so you can see improvement, not just guess at it.
- Uninstaller, context-menu manager and browser-extension manager to strip out the bloat other tools leave behind.
- Registry cleaning and defrag, broken-shortcut fixer and RAM optimiser for the finishing touches.
Privacy & security
- Privacy-track cleaning — recent-files lists and usage traces, with a cookie whitelist so you stay signed in where you want to.
- Secure file shredder for anything you want gone for good, plus file recovery for anything deleted by mistake.
- Network tools for flushing the DNS cache and sorting out common connection niggles.
Keeping an eye on things
- One-click maintenance for when you just want it sorted, and scheduled cleaning so it keeps itself tidy — a feature most rivals charge for.
- Disk health (SMART) monitoring to warn you before a failing drive takes your data with it.
- A monitoring dashboard and system-info panel so you can keep tabs on the machine at a glance.
The Safety Features That Actually Matter
Most "PC cleaner horror stories" come from tools that delete too much, too eagerly, with no way back. Chiltern Cleaner is built the other way round:
- Preview before it deletes. Every clean can be run as a dry run first — you see precisely what would go before anything does.
- Registry backup + one-click restore. It saves a backup before any registry change, so undoing it is a single click.
- System Restore point. It can create a Windows restore point before bigger jobs, for a full belt-and-braces safety net.
- An audit log of what was cleaned and when — so there's always a record. That's genuinely rare in this category.
- Skips files in use and leaves protected system files well alone.
How It Compares to the Big Names
The popular cleaners — CCleaner, BleachBit, Glary Utilities, Wise Care 365 and Advanced SystemCare — are capable tools, and I'm not going to pretend otherwise. But they all make trade-offs Chiltern Cleaner is deliberately built to avoid: paywalled features, adverts and upsells, or (in BleachBit's case) a very bare-bones experience. Here's the honest picture on the things I think actually matter:
| What matters | Chiltern Cleaner | CCleaner | BleachBit | Glary | Wise Care | Adv. SystemCare |
|---|---|---|---|---|---|---|
| Cost to you | Free with any service | £25–45/yr for Pro | Free | ~£20/yr for Pro | ~£30/yr for Pro | ~£20/yr for Pro |
| Ads / upsells / bundled extras | None | Upgrade prompts | None | Some | Some | Bundles IObit tools |
| Scheduled cleaning | Included | Pro only | No | Pro only | Pro only | Pro only |
| Preview before deleting | Yes (dry run) | Analyse first | Preview | Partial | Partial | Partial |
| Registry backup + restore | Yes | Yes | Avoids registry | Yes | Yes | Yes |
| Audit log of what was cleaned | Yes | Basic log | No | No | No | No |
| Runs only when opened | Yes | Background service | Yes | Background parts | Background parts | Heavy background |
| Local, human support | Yes — it's my shop | Ticket/forum | Community | Ticket | Ticket | Ticket |
Competitor pricing and features are based on my own research and each vendor's published plans at the time of writing (July 2026); they change their tiers regularly, so treat the figures as a guide.
To be fair to them: CCleaner has the broadest cleaning coverage and the most polished shredding options. BleachBit is free and open-source and deservedly popular with the technical crowd — it just deliberately keeps things minimal (no system tools, no one-click). Glary Utilities has the widest toolbox of the lot. Wise Care 365 and Advanced SystemCare are slick, but they lean hardest on the "buy Pro" and bundled-extras model, and Advanced SystemCare in particular is heavy on background services.
Where Chiltern Cleaner earns its place is the combination: a full toolbox and the safety features and no cost, ads or subscription — plus one thing none of them can offer, which is a local person who built it and can sort you out face to face.
An honest limit: a couple of the big suites bundle things Chiltern Cleaner deliberately doesn't try to be — a full antivirus, or a driver updater, for instance. I'd rather do cleaning and maintenance really well than half-do a dozen jobs. For virus removal, that's a proper hands-on service — see my virus & malware removal page.
Who It's For
If your PC feels sluggish, the drive's filling up, or it takes an age to start, Chiltern Cleaner will help — safely. It's ideal for anyone who wants their machine kept in good order without paying a yearly fee, wading through adverts, or risking a tool that deletes the wrong thing. And because it's the same tool I use in the workshop, you're getting workshop standards on your own desk.
It pairs naturally with the other things that keep a PC quick — an SSD upgrade if you're still on a mechanical hard drive, and the habits in my computer maintenance guide. Software cleaning gets you a long way; sometimes a slow laptop needs a bit of both.
