The Mark Cave Soft Washing Podcast SoftWash UK
Your Guide to Softwashing
Hello, I’m Mark Cave, founder of SoftWash UK and Mr Clever Clean.
Welcome to Your Guide to Softwashing, the podcast for anyone who wants to understand professional softwashing and exterior cleaning in the UK.
Whether you are new to the industry, adding softwashing to an existing cleaning business or already working as an experienced contractor, each episode is designed to help you achieve better results, work more safely and build a more professional business.
Drawing on more than a decade of industry experience, I explore the science, chemistry, equipment, techniques, safety and business principles behind effective exterior cleaning.
Topics include sodium hypochlorite, biocides, surfactants, acids, specialist cleaners, dilution, dwell time, application rates, rinsing, test patches and safe chemical handling.
We also cover roof cleaning, render cleaning, cladding, patios, driveways, block paving, concrete, brickwork, natural stone, tarmac, resin-bound surfaces, timber, decking, composite materials, UPVC, gutters, conservatories and other exterior surfaces.
Episodes explore the treatment of algae, moss, lichen, mould, black spot, rust, lead staining, oil, efflorescence, pollution and other organic or inorganic contamination.
You will also hear practical guidance on:
* Surface identification and stain diagnosis
* Choosing the correct cleaning method
* Equipment, pumps, hoses, injectors and dosage systems
* Roof access, runoff control and plant protection
* COSHH, RAMS, PPE, storage and emergency planning
* Pricing, quoting, customer communication and business growth
* Commercial work, maintenance plans and recurring income
* Real-world case studies, member questions and troubleshooting
The podcast answers the questions contractors regularly ask:
What chemical should I use?
What strength should I start with?
Should the treatment be rinsed or left to work?
Why has the staining not disappeared?
How should I price the job?
What risks should I identify before starting?
When should I walk away?
The aim is to help you understand not only what to use, but why, when and how to use it responsibly.
SoftWash UK also provides specialist chemicals, equipment, free educational resources and the CPD Certified SoftWash UK Training Course.
The course includes chemistry, surfaces, application methods, health and safety, business practices and practical assessment, together with 12 months’ National Association of Softwash membership, ongoing support, accreditation materials and directory listings.
Follow and subscribe so you never miss an episode.
Thank you for supporting independent UK exterior cleaning education.
